In any case, if you feel like working on some of those +projects, or anything else in PyPy, pop up on IRC or write to us on the +`mailing list`_. + +Numpy improvements +------------------ + +This is more of a project-container than a single project. Possible ideas: + +* experiment with auto-vectorization using SSE or implement vectorization + without automatically detecting it for array operations. + +* improve numpy, for example implement memory views. + +* interface with fortran/C libraries. + +Improving the jitviewer +------------------------ + +Analyzing performance of applications is always tricky. We have various +tools, for example a `jitviewer`_ that help us analyze performance. + +The jitviewer shows the code generated by the PyPy JIT in a hierarchical way, +as shown by the screenshot below: + + - at the bottom level, it shows the Python source code of the compiled loops + + - for each source code line, it shows the corresponding Python bytecode + + - for each opcode, it shows the corresponding jit operations, which are the + ones actually sent to the backend for compiling (such as ``i15 = i10 < + 2000`` in the example) + +.. image:: image/jitviewer.png + +We would like to add one level to this hierarchy, by showing the generated +machine code for each jit operation. The necessary information is already in +the log file produced by the JIT, so it is "only" a matter of teaching the +jitviewer to display it. Ideally, the machine code should be hidden by +default and viewable on request. + +The jitviewer is a web application based on flask and jinja2 (and jQuery on +the client): if you have great web developing skills and want to help PyPy, +this is an ideal task to get started, because it does not require any deep +knowledge of the internals. + +Translation Toolchain +--------------------- + +* Incremental or distributed translation. + +* Allow separate compilation of extension modules. + +Work on some of other languages +------------------------------- + +There are various languages implemented using the RPython translation toolchain. +One of the most interesting is the `JavaScript implementation`_, but there +are others like scheme or prolog.

The goal of that is to move as many +operations as possible out of the loop making them executed only once +and not every iteration. This we propose to achieve by loop peeling. It +leaves the loop body intact, but prefixes it with one iteration of the +loop. This operation by itself will not achieve anything. But if it is +combined with other optimizations it can increase the effectiveness of +those optimizations. For many optimization of interest some care has +to be taken when they are combined with loop peeling. This is +described below by first explaining the loop peeling optimization +followed by a set of other optimizations and how they interact with +loop peeling. + +\subsection{Loop peeling} +Loop peeling is achieved by inlining the trace at the end of +itself. The input arguments of the second iteration are replaced with +the jump arguments of the first iterations and then the arguments of all +the operations are updated to operate on the new input arguments. To +keep the single-assignment form new variables has to be introduced as +the results of all the operations. The first iteration of the loop +will end with a jump to the second iteration of the loop while the +second iteration will end with a jump to itself. This way the first +copy of the trace only be executed once while the second copy will be +used for every other iteration. The rationality here is that the +optimizations below typically will be able to optimize the second copy +more efficiently than the first. The trace from Figure~\ref{fig:unopt-trace} would +after this operation become the trace in Figure~\ref{fig:peeled-trace}. + +\begin{figure} +\begin{lstlisting}[mathescape,numbers = right,basicstyle=\setstretch{1.05}\ttfamily\scriptsize] +$l_0$($p_{0}$, $p_{1}$): +# inside f: y = y.add(step) +guard_class($p_{1}$, BoxedInteger) + # inside BoxedInteger.add + $i_{2}$ = get($p_{1}$, intval) + guard_class($p_{0}$, BoxedInteger) + # inside BoxedInteger.add__int + $i_{3}$ = get($p_{0}$, intval) + $i_{4}$ = int_add($i_{2}$, $i_{3}$) + $p_{5}$ = new(BoxedInteger) + # inside BoxedInteger.__init__ + set($p_{5}$, intval, $i_{4}$) +jump($l_1$, $p_{0}$, $p_{5}$) + +$l_1$($p_{0}$, $p_{5}$): +# inside f: y = y.add(step) +guard_class($p_{5}$, BoxedInteger) + # inside BoxedInteger.add + $i_{6}$ = get($p_{5}$, intval) + guard_class($p_{0}$, BoxedInteger) + # inside BoxedInteger.add__int + $i_{7}$ = get($p_{0}$, intval) + $i_{8}$ = int_add($i_{6}$, $i_{7}$) + $p_{9}$ = new(BoxedInteger) + # inside BoxedInteger.__init__ + set($p_{9}$, intval, $i_{8}$) +jump($l_1$, $p_{0}$, $p_{9}$) +\end{lstlisting} +\caption{An Unoptimized Trace of the Example Interpreter} +\label{fig:peeled-trace} +\end{figure} + +When applying the following optimizations to this two iteration trace +some care has to taken as to how the jump arguments of both +iterations and the input arguments of the second iteration are +treated. It has to be ensured that the second iteration stays a proper +trace in the sens that the operations within it only operations on +variables that are either among the input arguments of the second iterations +or are produced within the second iterations. To ensure this we need +to introduce a bit of formalism. + +The original trace (prior too peeling) consists of three parts. +A vector of input +variables, $I=\left(I_1, I_2, \cdots, I_{|I|}\right)$, a list of non +jump operations and a single +jump operation. The jump operation contains a vector of jump variables, +$J=\left(J_1, J_2, \cdots, J_{|J|}\right)$, that are passed as the input variables of the target loop. After +loop peeling there will be a second copy of this trace with input +variables equal to the jump arguments of the first copy, $J$, and jump +arguments $K$. Looking back at our example we have +\begin{equation} + %\left\{ + \begin{array}{lcl} + I &=& \left( p_0, p_1 \right) \\ + J &=& \left( p_0, p_5 \right) \\ + K &=& \left( p_0, p_9 \right) \\ + \end{array} + %\right. + . +\end{equation} +To construct the second iteration from the first we also need a +function, $m$, mapping the variables of the first iteration onto the +variables of the second. This function is constructed during the +inlining. It is initialized by mapping the input arguments, $I$, to +the jump arguments $J$, +\begin{equation} + m\left(I_i\right) = J_i \ \text{for}\ i = 1, 2, \cdots |I| . +\end{equation} +In the example that means (XXX which notation do we prefer?) +\begin{equation} + m(v) = + \left\{ + \begin{array}{lcl} + p_0 &\text{if}& v=p_0 \\ + p_5 &\text{if}& v=p_1 \\ + \end{array} + \right. + . +\end{equation} +\begin{equation} + %\left\{ + \begin{array}{lcl} + m\left(p_0\right) &=& p_0 \\ + m\left(p_1\right) &=& p_5 + \end{array} + %\right. + . +\end{equation} +Each operation in the trace is inlined in the order they are +executed. To inline an operation with argument vector +$A=\left(A_1, A_2, \cdots, A_{|A|}\right)$ producing the variable $v$ +a new variable, $\hat v$ is introduced. The inlined operation will +produce $\hat v$ from the input arguments +\begin{equation} + \left(m\left(A_1\right), m\left(A_2\right), + \cdots, m\left(A_{|A|}\right)\right) . +\end{equation} +Before the +next operation is inlined, $m$ is extend by making $m\left(v\right) = \hat +v$. After all the operations in the example have been inlined we have +\begin{equation} + %\left\{ + \begin{array}{lcl} + m\left(p_0\right) &=& p_0 \\ + m\left(p_1\right) &=& p_5 \\ + m\left(i_2\right) &=& i_6 \\ + m\left(i_3\right) &=& i_7 \\ + m\left(i_4\right) &=& i_8 \\ + m\left(p_5\right) &=& p_9 \\ + \end{array} + %\right. + . +\end{equation} + +\subsection{Redundant guard removal} +No special concerns needs to be taken when implementing redundant +guard removal together with loop peeling.

Its presence gives an unusual and powerful perspective on the specialization process. The second technique is representations, a theory of data-oriented specialization generalizing the traditional specialization domains (i.e. the compile-time/run-time dichotomy).}, + booktitle = {{PEPM}}, + publisher = {{ACM}}, + author = {Rigo, Armin}, + year = {2004}, + keywords = {{JIT}, Python} +}, + + at inproceedings{sullivan_dynamic_2003, + address = {San Diego, California}, + title = {Dynamic native optimization of interpreters}, + isbn = {1-58113-655-2}, + url = {http://portal.acm.org/citation.cfm?id=858570.858576}, + doi = {10.1145/858570.858576}, + abstract = {For domain specific languages, "scripting languages", dynamic languages, and for virtual machine-based languages, the most straightforward implementation strategy is to write an interpreter. A simple interpreter consists of a loop that fetches the next bytecode, dispatches to the routine handling that bytecode, then loops. There are many ways to improve upon this simple mechanism, but as long as the execution of the program is driven by a representation of the program other than as a stream of native instructions, there will be some "interpretive {overhead".There} is a long history of approaches to removing interpretive overhead from programming language implementations. In practice, what often happens is that, once an interpreted language becomes popular, pressure builds to improve performance until eventually a project is undertaken to implement a native Just In Time {(JIT)} compiler for the language. Implementing a {JIT} is usually a large effort, affects a significant part of the existing language implementation, and adds a significant amount of code and complexity to the overall code {base.In} this paper, we present an innovative approach that dynamically removes much of the interpreted overhead from language implementations, with minimal instrumentation of the original interpreter. While it does not give the performance improvements of hand-crafted native compilers, our system provides an appealing point on the language implementation spectrum.}, + booktitle = {Workshop on Interpreters, virtual machines and emulators}, + publisher = {{ACM}}, + author = {Sullivan, Gregory T. and Bruening, Derek L. and Baron, Iris and Garnett, Timothy and Amarasinghe, Saman}, + year = {2003} +} \ No newline at end of file diff --git a/talk/iwtc11/paper.tex b/talk/iwtc11/paper.tex --- a/talk/iwtc11/paper.tex +++ b/talk/iwtc11/paper.tex @@ -25,29 +25,95 @@ % 11pt To set in 11-point type instead of 9-point. % authoryear To obtain author/year citation style instead of numeric. +\usepackage{ifthen} +\usepackage{fancyvrb} +\usepackage{color} +\usepackage{ulem} +\usepackage{xspace} +\usepackage{epsfig} +\usepackage{amssymb} \usepackage{amsmath} +\usepackage{amsfonts} +\usepackage[utf8]{inputenc} +\usepackage{setspace} + +\usepackage{listings} + +\usepackage[T1]{fontenc} \usepackage{setspace} \usepackage{listings} +\usepackage{beramono} + + +\definecolor{gray}{rgb}{0.3,0.3,0.3} + +\lstset{ + basicstyle=\setstretch{1.05}\ttfamily\footnotesize, + language=Python, + keywordstyle=\bfseries, + stringstyle=\color{blue}, + commentstyle=\color{gray}\textit, + fancyvrb=true, + showstringspaces=false, + %keywords={def,while,if,elif,return,class,get,set,new,guard_class} + numberstyle = \tiny, + numbersep = -20pt, +} + + +\newboolean{showcomments} +\setboolean{showcomments}{true} +\ifthenelse{\boolean{showcomments}} + {\newcommand{\nb}[2]{ + \fbox{\bfseries\sffamily\scriptsize#1} + {\sf\small$\blacktriangleright$\textit{#2}$\blacktriangleleft$} + } + \newcommand{\version}{\emph{\scriptsize$-$Id: main.tex 19055 2008-06-05 11:20:31Z cfbolz $-$}} + } + {\newcommand{\nb}[2]{} + \newcommand{\version}{} + } + +\newcommand\cfbolz[1]{\nb{CFB}{#1}} +\newcommand\arigo[1]{\nb{AR}{#1}} +\newcommand\fijal[1]{\nb{FIJAL}{#1}} +\newcommand\david[1]{\nb{DAVID}{#1}} +\newcommand\anto[1]{\nb{ANTO}{#1}} +\newcommand\reva[1]{\nb{Reviewer 1}{#1}} +\newcommand\revb[1]{\nb{Reviewer 2}{#1}} +\newcommand\revc[1]{\nb{Reviewer 3}{#1}} +\newcommand{\commentout}[1]{} +\newcommand{\ignore}[1]{} % {{\tt \small ignore(#1)}} + +\newcommand\ie{i.e.,\xspace} +\newcommand\eg{e.g.,\xspace} +\newcommand{\etal}{\emph{et al.}\xspace} + +\normalem + +\let\oldcite=\cite + +\renewcommand\cite[1]{\ifthenelse{\equal{#1}{XXX}}{[citation~needed]}{\oldcite{#1}}} \begin{document} -\conferenceinfo{WXYZ '05}{date, City.} -\copyrightyear{2005} +\conferenceinfo{IWTC '11}{XXX} +\copyrightyear{2011} \copyrightdata{[to be supplied]} -\titlebanner{banner above paper title} % These are ignored unless -\preprintfooter{short description of paper} % 'preprint' option specified. +\titlebanner{draft} % These are ignored unless +%\preprintfooter{short description of paper} % 'preprint' option specified. -\title{Title Text} -\subtitle{Subtitle Text, if any} +\title{Loop Invariant Code Motion in PyPy's Tracing JIT} +%\subtitle{Subtitle Text, if any} -\authorinfo{Name1} +\authorinfo{Hakan Ardo XXX} {Affiliation1} - {Email1} -\authorinfo{Name2\and Name3} - {Affiliation2/3} - {Email2/3} + {hakan at debian.org} +\authorinfo{Carl Friedrich Bolz} + {Heinrich-Heine-Universität Düsseldorf} + {cfbolz at gmx.de} \maketitle @@ -55,13 +121,13 @@ This is the text of the abstract. \end{abstract} -\category{CR-number}{subcategory}{third-level} +\category{D.3.4}{Programming Languages}{Processors}[code generation, +incremental compilers, interpreters, run-time environments] \terms -term1, term2 +Languages, Performance, Experimentation -\keywords -keyword1, keyword2 +\keywords{Tracing JIT, Optimization, Loop-Invariant Code Motion} \section{Introduction} @@ -132,8 +198,8 @@ \label{fig:objmodel} \end{figure} -Using these classes to implement arithmetic shows the basic problem of a -dynamic language implementation.

That means that the jit compilers generated for all +interpreters implemented within PyPy now can take advantage of +it. Benchmarks have been executed for a few different interpreters and +we see improvements in several cases. The ideal loop for this optimization +would be short numerical calculations with no failing guards and no +external calls. + +\subsection{Python} +The python interpreter of the PyPy framework is a complete python +version 2.7 compatible interpreter. A set of numerical +calculations where implemented in both python and in C and their +runtimes compared. The benchmarks are +\begin{itemize} +\item {\bf sqrt}: approximates the square root of $y$ as $x_\infty$ + with $x_0=y/2$ and $x_k = \left( x_{k-1} + y/x_{k-1} \right) / + 2$. There are three different versions of this benchmark where $x_k$ + is represented with different type of objects: int's, float's and + Fix16's. The later, Fix16, is a custom class that implements + fixpoint arithmetic with 16 bits precision. In python there is only + a single implementation of the benchmark that gets specialized + depending on the class of it's input argument, $y$, while in C, + there is three different implementations. +\item {\bf conv3}: one dimensional convolution with a kernel of fixed + size $3$. +\item {\bf conv5}: one dimensional convolution with a kernel of fixed + size $5$. +\item {\bf conv3x3}: two dimensional convolution with kernel of fixed + size $3 \times 3$ using a custom class to represent two dimensional + arrays. +\item {\bf dilate3x3}: two dimensional dilation with kernel of fixed + size $3 \times 3$. This is similar to convolution but instead of + summing over the elements, the maximum is taken. That places a + external call to a max function within the loop that prevents some + of the optimizations. +\item {\bf sobel}: an low level video processing algorithm used to + locate edges in an image. It calculated the gradient magnitude + using sobel derivatives. The algorithm is in python implemented + on top of a custom image class that is specially designed for the + problem. It ensures that there will be no failing guards, and makes + a lot of the two dimension index calculations loop invariant. The + intention there is twofold. It shows that the performance impact of + having wrapper classes giving objects some application specific + properties is negligible.

This means that various garbage +collectors can be written for specialized purposes, or even various +experiments can be done for the general purpose. Examples + +* An incremental garbage collector that has specified maximal pause times, + crucial for games + +* A garbage collector that compact memory better for mobile devices + +* A concurrent garbage collector (a lot of work) + +Remove the GIL +-------------- + +This is a major task that requires lots of thinking. However, few subprojects +can be potentially specified, unless a better plan can be thought out: + +* A thread-aware garbage collector + +* Better RPython primitives for dealing with concurrency + +* JIT passes to remove locks on objects + +* (maybe) implement locking in Python interpreter + +* alternatively, look at Software Transactional Memory + +Introduce new benchmarks +------------------------ + +We're usually happy to introduce new benchmarks. Please consult us +before, but in general something that's real-world python code +and is not already represented is welcome. We need at least a standalone +script that can run without parameters. Example ideas (benchmarks need +to be got from them!): + +* `hg` + +* `sympy` + +Experiment (again) with LLVM backend for RPython compilation +------------------------------------------------------------ + +We already tried working with LLVM and at the time, LLVM was not mature enough +for our needs. It's possible that this has changed, reviving the LLVM backend +(or writing new from scratch) for static compilation would be a good project. + +.. _`issue tracker`: http://bugs.pypy.org +.. _`mailing list`: http://mail.python.org/mailman/listinfo/pypy-dev +.. _`jitviewer`: http://bitbucket.org/pypy/jitviewer +.. _`JavaScript implementation`: https://bitbucket.org/pypy/lang-js/overview diff --git a/pypy/jit/backend/llgraph/llimpl.py b/pypy/jit/backend/llgraph/llimpl.py --- a/pypy/jit/backend/llgraph/llimpl.py +++ b/pypy/jit/backend/llgraph/llimpl.py @@ -600,15 +600,15 @@ # return _op_default_implementation - def op_debug_merge_point(self, _, value, recdepth): + def op_debug_merge_point(self, _, *args): from pypy.jit.metainterp.warmspot import get_stats - loc = ConstPtr(value)._get_str() try: stats = get_stats() except AttributeError: pass else: - stats.add_merge_point_location(loc) + stats.add_merge_point_location(args[1:]) + pass def op_guard_true(self, _, value): if not value: @@ -820,6 +820,12 @@ raise NotImplementedError def op_call(self, calldescr, func, *args): + return self._do_call(calldescr, func, args, call_with_llptr=False) + + def op_call_release_gil(self, calldescr, func, *args): + return self._do_call(calldescr, func, args, call_with_llptr=True) + + def _do_call(self, calldescr, func, args, call_with_llptr): global _last_exception assert _last_exception is None, "exception left behind" assert _call_args_i == _call_args_r == _call_args_f == [] @@ -838,7 +844,8 @@ else: raise TypeError(x) try: - return _do_call_common(func, args_in_order, calldescr) + return _do_call_common(func, args_in_order, calldescr, + call_with_llptr) except LLException, lle: _last_exception = lle d = {'v': None, @@ -1480,17 +1487,20 @@ 'v': lltype.Void, } -def _do_call_common(f, args_in_order=None, calldescr=None): +def _do_call_common(f, args_in_order=None, calldescr=None, + call_with_llptr=False): ptr = llmemory.cast_int_to_adr(f).ptr PTR = lltype.typeOf(ptr) if PTR == rffi.VOIDP: # it's a pointer to a C function, so we don't have a precise # signature: create one from the descr + assert call_with_llptr is True ARGS = map(kind2TYPE.get, calldescr.arg_types) RESULT = kind2TYPE[calldescr.typeinfo] FUNC = lltype.FuncType(ARGS, RESULT) func_to_call = rffi.cast(lltype.Ptr(FUNC), ptr) else: + assert call_with_llptr is False FUNC = PTR.TO ARGS = FUNC.ARGS func_to_call = ptr._obj._callable diff --git a/pypy/jit/backend/llgraph/runner.py b/pypy/jit/backend/llgraph/runner.py --- a/pypy/jit/backend/llgraph/runner.py +++ b/pypy/jit/backend/llgraph/runner.py @@ -134,7 +134,7 @@ old, oldindex = faildescr._compiled_fail llimpl.compile_redirect_fail(old, oldindex, c) - def compile_loop(self, inputargs, operations, looptoken, log=True): + def compile_loop(self, inputargs, operations, looptoken, log=True, name=''): """In a real assembler backend, this should assemble the given list of operations.

Because a tracing JIT +produces only linear pieces of code without control flow joins, many +optimization passes on traces can have a very simple structure. They often +consist of one forward pass through the trace, discarding and replacing +operations in the trace by simpler ones as they walk along it. This makes +optimization of traces be very similar to symbolic execution. Many +difficult problems in traditional optimizers become tractable if the optimizer +does not need to deal with control flow merges. + +One disadvantage of this simplicity is that such simple forward-passing +optimizers ignore the only bit of control flow they have available, which is +the fact that most traces actually represent loops. Making use of this +information is necessary to perform such optimizations as loop-invariant code +motion or optimizations that improve across several iterations of the loop. +Having to deal with this property of traces makes optimizers immediately more +complex, as a more global view of a trace needs to be considered when +optimizing. + +In this paper we want to address this problem by proposing a simple scheme that +makes it possible to turn simple optimizations using one forward pass into +optimizations that can do loop invariant code motion and similar loop-aware +improvements.

-This is a simplification and rewrite of the ideas from the Hybrid GC. -It uses a nursery for the young objects, and mark-and-sweep for the old -objects. This is a moving GC, but objects may only move once (from -the nursery to the old stage). - -The main difference with the Hybrid GC is that the mark-and-sweep -objects (the "old stage") are directly handled by the GC's custom -allocator, instead of being handled by malloc() calls. The gain is that -it is then possible, during a major collection, to walk through all old -generation objects without needing to store a list of pointers to them. -So as a first approximation, when compared to the Hybrid GC, the -Minimark GC saves one word of memory per old object. - -There are a number of environment variables that can be tweaked to -influence the GC. (Their default value should be ok for most usages.) -You can read more about them at the start of -`pypy/rpython/memory/gc/minimark.py`_. - -In more details: - -- The small newly malloced objects are allocated in the nursery (case 1). - All objects living in the nursery are "young". - -- The big objects are always handled directly by the system malloc(). - But the big newly malloced objects are still "young" when they are - allocated (case 2), even though they don't live in the nursery. - -- When the nursery is full, we do a minor collection, i.e. we find - which "young" objects are still alive (from cases 1 and 2). The - "young" flag is then removed. The surviving case 1 objects are moved - to the old stage. The dying case 2 objects are immediately freed. - -- The old stage is an area of memory containing old (small) objects. It - is handled by `pypy/rpython/memory/gc/minimarkpage.py`_. It is organized - as "arenas" of 256KB or 512KB, subdivided into "pages" of 4KB or 8KB. - Each page can either be free, or contain small objects of all the same - size. Furthermore at any point in time each object location can be - either allocated or freed. The basic design comes from ``obmalloc.c`` - from CPython (which itself comes from the same source as the Linux - system malloc()). - -- New objects are added to the old stage at every minor collection. - Immediately after a minor collection, when we reach some threshold, we - trigger a major collection. This is the mark-and-sweep step. It walks - over *all* objects (mark), and then frees some fraction of them (sweep). - This means that the only time when we want to free objects is while - walking over all of them; we never ask to free an object given just its - address. This allows some simplifications and memory savings when - compared to ``obmalloc.c``. - -- As with all generational collectors, this GC needs a write barrier to - record which old objects have a reference to young objects. - -- Additionally, we found out that it is useful to handle the case of - big arrays specially: when we allocate a big array (with the system - malloc()), we reserve a small number of bytes before. When the array - grows old, we use the extra bytes as a set of bits. Each bit - represents 128 entries in the array. Whenever the write barrier is - called to record a reference from the Nth entry of the array to some - young object, we set the bit number ``(N/128)`` to 1. This can - considerably speed up minor collections, because we then only have to - scan 128 entries of the array instead of all of them. - -- As usual, we need special care about weak references, and objects with - finalizers. Weak references are allocated in the nursery, and if they - survive they move to the old stage, as usual for all objects; the - difference is that the reference they contain must either follow the - object, or be set to NULL if the object dies. And the objects with - finalizers, considered rare enough, are immediately allocated old to - simplify the design. In particular their ``__del__`` method can only - be called just after a major collection. - -- The objects move once only, so we can use a trick to implement id() - and hash(). If the object is not in the nursery, it won't move any - more, so its id() and hash() are the object's address, cast to an - integer. If the object is in the nursery, and we ask for its id() - or its hash(), then we pre-reserve a location in the old stage, and - return the address of that location. If the object survives the - next minor collection, we move it there, and so its id() and hash() - are preserved. If the object dies then the pre-reserved location - becomes free garbage, to be collected at the next major collection. - - .. include:: _ref.txt diff --git

The - "young" flag is then removed. The surviving case 1 objects are moved - to the old stage.

When the array - grows old, we use the extra bytes as a set of bits. Each bit - represents 128 entries in the array. Whenever the write barrier is - called to record a reference from the Nth entry of the array to some - young object, we set the bit number ``(N/128)`` to 1. This can - considerably speed up minor collections, because we then only have to - scan 128 entries of the array instead of all of them. - -- As usual, we need special care about weak references, and objects with - finalizers.

The - "young" flag is then removed. The surviving case 1 objects are moved - to the old stage. The dying case 2 objects are immediately freed. - -- The old stage is an area of memory containing old (small) objects. It - is handled by `pypy/rpython/memory/gc/minimarkpage.py`_. It is organized - as "arenas" of 256KB or 512KB, subdivided into "pages" of 4KB or 8KB. - Each page can either be free, or contain small objects of all the same - size. Furthermore at any point in time each object location can be - either allocated or freed. The basic design comes from ``obmalloc.c`` - from CPython (which itself comes from the same source as the Linux - system malloc()). - -- New objects are added to the old stage at every minor collection. - Immediately after a minor collection, when we reach some threshold, we - trigger a major collection. This is the mark-and-sweep step. It walks - over *all* objects (mark), and then frees some fraction of them (sweep). - This means that the only time when we want to free objects is while - walking over all of them; we never ask to free an object given just its - address. This allows some simplifications and memory savings when - compared to ``obmalloc.c``. - -- As with all generational collectors, this GC needs a write barrier to - record which old objects have a reference to young objects. - -- Additionally, we found out that it is useful to handle the case of - big arrays specially: when we allocate a big array (with the system - malloc()), we reserve a small number of bytes before. When the array - grows old, we use the extra bytes as a set of bits. Each bit - represents 128 entries in the array. Whenever the write barrier is - called to record a reference from the Nth entry of the array to some - young object, we set the bit number ``(N/128)`` to 1. This can - considerably speed up minor collections, because we then only have to - scan 128 entries of the array instead of all of them. - -- As usual, we need special care about weak references, and objects with - finalizers. Weak references are allocated in the nursery, and if they - survive they move to the old stage, as usual for all objects; the - difference is that the reference they contain must either follow the - object, or be set to NULL if the object dies. And the objects with - finalizers, considered rare enough, are immediately allocated old to - simplify the design. In particular their ``__del__`` method can only - be called just after a major collection. - -- The objects move once only, so we can use a trick to implement id() - and hash(). If the object is not in the nursery, it won't move any - more, so its id() and hash() are the object's address, cast to an - integer. If the object is in the nursery, and we ask for its id() - or its hash(), then we pre-reserve a location in the old stage, and - return the address of that location. If the object survives the - next minor collection, we move it there, and so its id() and hash() - are preserved.

In order to make prevent the compiler and linker from using anything introduced in a later OS, a sysroot should be specified, pointing to an appropriate SDK. However, PyPy as-is doesn't even run terribly well on the latest (and most popular) release of Mac OS X. Supporting older releases amounts to wishful thinking.

This is useful also for fields that are not immutable. Do you maybe feel like generalizing this?

Not all external values flush the heap cache. A lot of external calls just read things, don't write. Also, being used as an argument of an external call is just one reason for an object to escape.

We've + already blogged on the topic of `our plans for NumPy`_. +c) Having packages in the various OS's repositories would be a big help in + getting users up and running. + +A huge thanks to everyone who responded!

We present a high-level continuation-based Prolog interpreter based on the {PyPy} project. The {PyPy} project makes it possible to easily and efficiently implement dynamic languages. It provides tools that automatically generate a just-in-time compiler for a given interpreter of the target language, by using partial evaluation techniques. The resulting Prolog implementation is surprisingly efficient: it clearly outperforms existing interpreters of Prolog in high-level languages such as Java. Moreover, on some benchmarks, our system outperforms state-of-the-art {WAM-based} Prolog implementations.

Because a tracing JIT +produces only linear pieces of code without control flow joins, many +optimization passes on traces can have a very simple structure. They often +consist of one forward pass replacing operations by simpler ones or even +discarding them as they walk along it. This makes +optimization of traces very similar to symbolic execution. Also, many +difficult problems in traditional optimizers become tractable if the optimizer +does not need to deal with control flow merges. + +One disadvantage of this simplicity is that such simple forward-passing +optimizers ignore the only bit of control flow they have available, which is +the fact that most traces actually represent loops. Making use of this +information is necessary to perform optimizations that take the whole loop into +account, such as loop-invariant code +motion or optimizations that improve across several iterations of the loop. +Having to deal with this property of traces complicates the optimization passes, +as a more global view of a trace needs to be considered when optimizing. + +In this paper we want to address this problem by proposing a simple scheme that +makes it possible to turn optimizations using one forward pass into +optimizations that can do loop invariant code motion and similar loop-aware +improvements. Using this scheme one does not need to change the underlying +optimization much to get these advantages. + +The resulting optimizations one gets using this scheme are in no way novel, most +of them are well-known loop optimizations. However, the way to implement them is +a lot simpler than directly implementing loop-aware optimizations. + +% loop peeling does a lot more than loop-invariant code motion +% take this loop as an example: +% [i1, i2] +% i3 = i1 + 1 +% i4 = i2 + 1 +% escape(i4) +% jump(i2, i3) +% none of the operations is loop-invariant, but loop peeling will still remove the second addition + +\section{Background: PyPy} +\label{sec:PyPy} + +The work described in this paper was done in the context of the PyPy +project\footnote{\texttt{http://pypy.org}}. PyPy is a framework for implementing +dynamic languages efficiently \cite{armin_rigo_pypys_2006}. When implementing a +language with PyPy, one writes an interpreter for the language in RPython +\cite{davide_ancona_rpython:_2007}. RPython (``Restricted Python``) is a subset +of Python chosen in such a way that it can be efficiently translated to a +C-based VM by performing type inference. + +Many low-level aspects of the final VM are not contained within the interpreter +implementation but are inserted during translation to C. Examples for this are a +garbage collector and also a tracing JIT compiler \cite{bolz_tracing_2009}. + +PyPy's tracing JIT compiler traces on the level of RPython programs. Thus it +actually traces the execution of an interpreter written in RPython, not of the +program itself. This makes the details of the object model of the implemented +language transparent and optimizable by the tracing JIT. In the context of this +paper, this aspect of PyPy's tracing JIT can be ignored. Instead, it is +sufficient to view PyPy's tracing JIT as a JIT for RPython. + + +% section PyPy (end) + +\section{Motivation} +\label{sec:Motivation} + +To motivate the approach we propose here, let's look at a trivial (unrealistic) +trace which corresponds to an infinite loop: + +\begin{lstlisting}[mathescape,numbers = right,basicstyle=\setstretch{1.05}\ttfamily\scriptsize] +$L_0$($i_{0}$): +$i_1$ = $i_0$ + 1 +print($i_1$) +jump($L_0$, $i_0$) +\end{lstlisting} + +The first line is a label $L_0$ with argument $i_0$. Every label has a list of +arguments. The \lstinline{print} operation just prints its argument (it is not +an operation that PyPy's tracing JIT really supports, we just use it for this +example). The \lstinline{jump} operation jumps back to the beginning of the +trace, listing the new values of the arguments of the trace. In this case, the +new value of $i_0$ is $i_0$, making it a loop-invariant. + +Because $i_0$ is loop-invariant, the addition could be moved out of the loop. +However, we want to get this effect using our existing optimization passes +without changing them too much. To achieve this, we peel one iteration off the +loop before running the optimizations. This peeling gives the following trace: + +\begin{lstlisting}[mathescape,numbers = right,basicstyle=\setstretch{1.05}\ttfamily\scriptsize] +$L_0$($i_{0}$): +$i_1$ = $i_0$ + 1 +print($i_1$) +jump($L_1$, $i_0$) + +$L_1$($i_{0}$): +$i_2$ = $i_0$ + 1 +print($i_2$) +jump($L_1$, $i_0$) +\end{lstlisting} + +The iteration of the loop that was peeled off (lines 1-4) is called the +\emph{preamble}, the loop afterwards the \emph{peeled loop}. + +Now the optimizer optimizes both of these two iterations of the loop together, +disregarding the \lstinline{jump} and the label in lines 4-6. Doing this, common +subexpression elimination will discover that the two additions are the same, and +replace $i_2$ with $i_1$. This leads to the following trace: + +\begin{lstlisting}[mathescape,numbers = right,basicstyle=\setstretch{1.05}\ttfamily\scriptsize] +$L_0$($i_{0}$): +$i_1$ = $i_0$ + 1 +print($i_1$) +jump($L_1$, $i_0$) + +$L_1$($i_{0}$): +print($i_1$) +jump($L_1$, $i_0$) +\end{lstlisting} + +This trace is malformed, because $i_1$ is used after the label $L_1$ without +being passed there, so we need to add $i_1$ as an argument to the label and pass +it along the \lstinline{jump}s: + +\begin{lstlisting}[mathescape,numbers = right,basicstyle=\setstretch{1.05}\ttfamily\scriptsize] +$L_0$($i_{0}$): +$i_1$ = $i_0$ + 1 +print($i_1$) +jump($L_1$, $i_0$, $i_1$) + +$L_1$($i_{0}$, $i_1$): +print($i_1$) +jump($L_1$, $i_0$, $i_1$) +\end{lstlisting} + +The final result is that the loop-invariant code was moved out of the loop into +the peeled-off iteration. Thus the addition is only executed in the first +iteration, while the result is reused in all further iterations. + +This scheme is quite powerful and generalizes to other optimizations than just +common subexpression elimination. It allows simple linear optimization passes to +perform loop-aware optimizations, such as loop-invariant code motion without +changing them at all. All that is needed is to peel off one iteration, then +apply simple one-pass optimizations and make sure that the necessary extra +arguments are inserted into the label of the loop itself and the jumps +afterwards. Giving the optimizations two iterations together +gives the optimization enough context to remove operations from the peeled loop, +because it detects that the operation was performed in the preamble already. + + +% section Motivation (end) + +\section{Running Example} +\label{sub:example} + +For the purpose of this paper, we are going to use a tiny interpreter for a dynamic language with + a very simple object +model, that just supports an integer and a float type (this example has been taken from a previous paper \cite{bolz_allocation_2011}). The objects support only +one operation, \lstinline{add}, which adds two objects (promoting ints to floats in a +mixed addition). The implementation of \lstinline{add} uses classical Smalltalk-like +double-dispatching. +%These classes could be part of the implementation of a very +%simple interpreter written in RPython. +The classes can be seen in +Figure~\ref{fig:objmodel} (written in RPython). + +\begin{figure} +\begin{lstlisting}[mathescape,basicstyle=\setstretch{1.05}\ttfamily\scriptsize] +class Base(object): + pass + +class BoxedInteger(Base): + def __init__(self, intval): + self.intval = intval + + def add(self, other): + return other.add__int(self.intval) + + def add__int(self, intother): + return BoxedInteger(intother + self.intval) + + def add__float(self, floatother): + floatvalue = floatother + float(self.intval) + return BoxedFloat(floatvalue) + + +class BoxedFloat(Base): + def __init__(self, floatval): + self.floatval = floatval + + def add(self, other): + return other.add__float(self.floatval) + + def add__int(self, intother): + floatvalue = float(intother) + self.floatval + return BoxedFloat(floatvalue) + + def add__float(self, floatother): + return BoxedFloat(floatother + self.floatval) + + +def f(y): + step = BoxedInteger(-1) + while True: + y = y.add(step) +\end{lstlisting} +\caption{An ``Interpreter'' for a Tiny Dynamic Language Written in RPython} +\label{fig:objmodel} +\end{figure} + +Using these classes to implement arithmetic shows the basic problem of many +dynamic language implementations. All the numbers are instances of either +\lstinline{BoxedInteger} or \lstinline{BoxedFloat}, therefore they consume space on the +heap. Performing many arithmetic operations produces lots of garbage quickly, +putting pressure on the garbage collector. Using double dispatching to +implement the numeric tower needs two method calls per arithmetic operation, +which is costly due to the method dispatch. + +Let us now consider a simple ``interpreter'' function \lstinline{f} that uses the +object model (see the bottom of Figure~\ref{fig:objmodel}). +Simply running this function is slow, because there are lots of virtual method +calls inside the loop, two for each +call to \lstinline{add}. These method calls need to check the type of the involved +objects every iteration. In addition, a lot of objects are created +when executing that loop, many of these objects are short-lived. +The actual computation that is performed by \lstinline{f} is simply a sequence of +float or integer additions (note that \lstinline{f} does not actually terminate, +but it is still instructive to look at the produced traces). + + +\begin{figure} +\begin{lstlisting}[mathescape,numbers = right,basicstyle=\setstretch{1.05}\ttfamily\scriptsize] +$L_0$($p_{0}$, $p_{1}$): +# inside f: y = y.add(step) +guard_class($p_{1}$, BoxedInteger) + # inside BoxedInteger.add + $i_{2}$ = get($p_{1}$, intval) + guard_class($p_{0}$, BoxedInteger) + # inside BoxedInteger.add__int + $i_{3}$ = get($p_{0}$, intval) + $i_{4}$ = $i_{2} + i_{3}$ + $p_{5}$ = new(BoxedInteger) + # inside BoxedInteger.__init__ + set($p_{5}$, intval, $i_{4}$) +jump($L_0$, $p_{0}$, $p_{5}$) +\end{lstlisting} +\caption{An Unoptimized Trace of the Example Interpreter} +\label{fig:unopt-trace} +\end{figure} + +If the function is executed using the tracing JIT, with \lstinline{y} being a +\lstinline{BoxedInteger}, the produced trace looks like the one of +Figure~\ref{fig:unopt-trace} (lines starting with a hash ``\#'' are comments). +The trace corresponds to one iteration of the while-loop in \lstinline{f}. + +The operations in the trace are indented +corresponding to the stack level of the function that contains the traced +operation. The trace is in single-assignment form, meaning that each variable is +assigned a value exactly once. The arguments $p_0$ and $p_1$ of the loop correspond +to the live variables \lstinline{y} and \lstinline{step} in the while-loop of +the original function. + +The label of the loop is $L_0$ and is used by the jump instruction to +identify it's jump target. + +The operations in the trace correspond to the operations in the RPython program +in Figure~\ref{fig:objmodel}: + +\begin{itemize} + \item \lstinline{new} creates a new object. + \item \lstinline{get} reads an attribute of an object. + \item \lstinline{set} writes to an attribute of an object. + \item \lstinline{guard_class} is a precise type check. It typically precedes + an (inlined) method call and is followed by the trace of the called method. +\end{itemize} + +Method calls in the trace are preceded by a \lstinline{guard_class} +operation, to check that the class of the receiver is the same as the one that +was observed during tracing.\footnote{\lstinline{guard_class} +performs a precise +class check, not checking for subclasses.} These guards make the trace specific +to the situation where \lstinline{y} is really a \lstinline{BoxedInteger}. When +the trace is turned into machine code and afterwards executed with +\lstinline{BoxedFloat}, the +first \lstinline{guard_class} instruction will fail and execution will continue +using the interpreter. + +\section{Making Trace Optimizations Loop Aware} + +XXX make clear that the preamble is not necessarily the \emph{first} iteration +of a loop + +Before the trace is passed to a backend compiling it into machine code +it needs to be optimized to achieve better performance. +The focus of this paper +is loop invariant code motion. The goal of that is to move as many +operations as possible out of the loop making them executed at most once +and not every iteration. This we propose to achieve by loop peeling. It +leaves the loop body intact, but prefixes it with one iteration of the +loop. This operation by itself will not achieve anything. But if it is +combined with other optimizations it can increase the effectiveness of +those optimizations. For many optimization of interest some care has +to be taken when they are combined with loop peeling. This is +described below by first explaining the loop peeling optimization +followed by a set of other optimizations and how they interact with +loop peeling. + +\subsection{Loop Peeling} + +\begin{figure} +\begin{center} +\includegraphics[scale=1]{figures/overview} +\end{center} +\caption{Overview of Loop Peeling} +\label{fig:overview} +\end{figure} + +XXX find reference of prior work on this + +Loop peeling is achieved by appending an copy of the traced iteration at +the end of itself. See Figure~\ref{fig:overview} for an illustration. +The first part (called \emph{preamble}) finishes with the jump the the second part +(called the \emph{peeled loop}). The second part end with the jump to itself. This way +the preamble will be executed only once while the peeled loop will +be used for every further iteration. New variable names have to be +introduced in the entire copied trace in order to maintian the SSA-property. +Note that the peeled loop is not necessary the \emph{first} iteration of the +loop execution, it is general enough to correspond to any iteration of the loop. +However, the peeled loop can then be optimized using the assumption that a +previous iteration has happened. + +When applying optimizations to this two-iteration trace +some care has to taken as to how the arguments of the two +\lstinline{jump} operations and the input arguments of the peeled loop are +treated. It has to be ensured that the peeled loop stays a proper +trace in the sense that the operations within it only operates on +variables that are either among its input arguments +or produced within the peeled loop. To ensure this we need +to introduce a bit of formalism. + +The original trace (prior to peeling) consists of three parts. +A vector of input +variables, $I=\left(I_1, I_2, \cdots, I_{|I|}\right)$, a list of non- +jump operations and a single +jump operation. The jump operation contains a vector of jump variables, +$J=\left(J_1, J_2, \cdots, J_{|J|}\right)$, that are passed as the input variables of the target loop. After +loop peeling there will be a second copy of this trace with input +variables equal to the jump arguments of the preamble, $J$, and jump +arguments $K$. Looking at the peeled version of our example in Figure~\ref{fig:peeled-trace} we have +\begin{equation} + %\left\{ + \begin{array}{lcl} + I &=& \left( p_0, p_1 \right) \\ + J &=& \left( p_0, p_5 \right) \\ + K &=& \left( p_0, p_9 \right) \\ + \end{array} + %\right. + . +\end{equation} +To construct the second copy of the trace (the peeled loop) from the +first (the preeamble) we need a +function $m$, mapping the variables of the preamble onto the +variables of the peeled loop. This function is constructed during the +copying. It is initialized by mapping the input arguments, $I$, to +the jump arguments $J$, +\begin{equation} + m\left(I_i\right) = J_i \ \text{for}\ i = 1, 2, \cdots |I| . +\end{equation} +In the example that means: + +\begin{equation} + %\left\{ + \begin{array}{lcl} + m\left(p_0\right) &=& p_0 \\ + m\left(p_1\right) &=& p_5 + \end{array} + %\right. + . +\end{equation} + + + +Each operation in the trace is copied in order. +To copy an operation $v=\text{op}\left(A_1, A_2, \cdots, A_{|A|}\right)$ +a new variable, $\hat v$ is introduced.

The guards from +the preamble might make the guards of the peeled loop +redundant and thus removed. Therefore one effect of combining redundant +guard removal with loop peeling is that loop-invariant guards are moved out of the +loop. The peeled loop of the example reduces to + +\begin{lstlisting}[mathescape,numbers = right,basicstyle=\setstretch{1.05}\ttfamily\scriptsize] +$L_1$($p_{0}$, $p_{5}$): +# inside f: y = y.add(step) + # inside BoxedInteger.add + $i_{6}$ = get($p_{5}$, intval) + # inside BoxedInteger.add__int + $i_{7}$ = get($p_{0}$, intval) + $i_{8}$ = $i_{6}+i_{7}$ + $p_{9}$ = new(BoxedInteger) + # inside BoxedInteger.__init__ + set($p_{9}$, intval, $i_{8}$) +jump($L_1$, $p_{0}$, $p_{9}$) +\end{lstlisting} + +The guard on $p_5$ on line 17 of Figure~\ref{fig:peeled-trace} can be +removed since $p_5$ is allocated on line 10 with a known class. The +guard on $p_0$ on line 20 can be removed since it is identical to the +guard on line 6. + +Note that the guard on $p_5$ is removed even though $p_5$ is not loop +invariant, which shows that loop invariant code motion is not the only +effect of loop peeling. Loop peeling can also remove guards that are implied by +the guards of the previous iteration. + + + +\subsection{Common Subexpression Elimination and Heap Optimizations} + +If a pure operation appears more than once in the trace with the same input +arguments, it only needs be executed the first time and then the result +can be reused for all other appearances. PyPy's optimizers can also remove +repeated heap reads if the intermediate operations cannot have changed their +value\footnote{We perform a simple type-based alias analysis to know which +writes can affect which reads. In addition writes on newly allocated objects +can never change the value of old existing ones.}. + +When that is combined with loop peeling, the single execution of the operation +is placed in the preamble. That is, loop invariant pure operations and heap +reads are moved out of the loop. + +Consider the \lstinline{get} operation on line 22 of +Figure~\ref{fig:peeled-trace}. The result of this operation can be +deduced to be $i_3$ from the \lstinline{get} operation on line +8. The optimization will thus remove line 22 from the trace and +replace $i_7$ with $i_3$. Afterwards the trace is no longer in the correct +form, because the argument $i_3$ is not passed along the loop arguments. It +thus needs to be added there. + +The trace from Figure~\ref{fig:peeled-trace} will therefore be optimized to: + +\begin{lstlisting}[mathescape,numbers = right,basicstyle=\setstretch{1.05}\ttfamily\scriptsize] +$L_0$($p_{0}$, $p_{1}$): +# inside f: y = y.add(step) +guard_class($p_{1}$, BoxedInteger) + # inside BoxedInteger.add + $i_{2}$ = get($p_{1}$, intval) + guard_class($p_{0}$, BoxedInteger) + # inside BoxedInteger.add__int + $i_{3}$ = get($p_{0}$, intval) + $i_{4}$ = $i_{2}+i_{3}$ + $p_{5}$ = new(BoxedInteger) + # inside BoxedInteger.__init__ + set($p_{5}$, intval, $i_{4}$) +jump($L_1$, $p_{0}$, $p_{5}$, $i_3$) + +$L_1$($p_{0}$, $p_{5}$, $i_3$): +# inside f: y = y.add(step) +guard_class($p_{5}$, BoxedInteger) + # inside BoxedInteger.add + $i_{6}$ = get($p_{5}$, intval) + guard_class($p_{0}$, BoxedInteger) + # inside BoxedInteger.add__int + $i_{8}$ = $i_{4}+i_{3}$ + $p_{9}$ = new(BoxedInteger) + # inside BoxedInteger.__init__ + set($p_{9}$, intval, $i_{8}$) +jump($L_1$, $p_{0}$, $p_{9}$, $i_3$) +\end{lstlisting} + +In general, after loop peeling and redundant operation removal the peeled loop +will no longer be in SSA form as it operates on variables that are the result +of pure operations in the preamble. The solution is to extend the input +arguments, $J$, with those variables. This will also extend the +jump arguments of the preamble, which is also $J$. +Implicitly that also extends the jump arguments of the peeled loop, $K$, +since they are the image of $J$ under $m$. For the example $I$ has to +be replaced by $\hat I$ which is formed by appending $i_3$ to $I$. +At the same time $K$ has to be replaced by +$\hat K$ which is formed by appending $m\left(i_3\right)=i_7$ to $K$. +The variable $i_7$ will then be replaced by $i_3$ by the heap caching +optimization as it has removed the variable $i_7$. + +In general what is needed is to keep track of +which variables from the preamble it reuses in the peeled loop. +It has to construct a vector, $H$, of such variables which +can be used to update the input and jump arguments using +\begin{equation} + \hat J = \left(J_1, J_2, \cdots, J_{|J|}, H_1, H_2, \cdots, H_{|H}\right) + \label{eq:heap-inputargs} +\end{equation} +and +\begin{equation} + \hat K = \left(K_1, K_2, \cdots, K_{|J|}, m(H_1), m(H_2), \cdots, m(H_{|H})\right) + . + \label{eq:heap-jumpargs} +\end{equation} +In the optimized trace $I$ is replaced by $\hat I$ and $K$ by $\hat +K$. + +\subsection{Allocation Removals} +PyPy's allocation removal optimization \cite{bolz_allocation_2011} makes it +possible to identify objects that are allocated within the loop but never +escape it. Those objects have to be allocated in the loop, but no outside +object ever gets a reference short lived objects with no references outside the +loop. This +is performed by processing the operations in order and +optimistically removing every \lstinline{new} operation. Later on if +it is discovered that a reference to the object escapes the loop, the +\lstinline{new} operation is inserted at this point. All operations +(\lstinline{get}, \lstinline{set} and \lstinline{guard}) on the removed objects +are also removed and the optimizer needs to keep track of the value of all used +attributes of the object. + +Consider again the original unoptimized trace of +Figure~\ref{fig:peeled-trace}. Line 10 contains the first +allocation. It is removed and $p_5$ is marked as allocation-removed. This means +that it refers to an object that has not yet been +(and might never be) allocated. Line 12 sets the \lstinline{intval} +attribute of $p_5$. This operation is also removed and the optimizer +registers that the attribute \lstinline{intval} of $p_5$ is $i_4$. + +When the optimizer reaches line 13 it needs to construct the +arguments of the \lstinline{jump} operation, which contains the +reference to the allocation-removed object in $p_5$. This can be achieved by +exploding $p_5$ into the fields of the allocation-removed object. +In this case there is only one such field and its value is +$i_4$, which means that $p_5$ is replaced with $i_4$ in the jump +arguments. + +In the general case, each allocation-removed object in the jump arguments is exploded into a +vector of variables containing the values of all registered +fields\footnote{This is sometimes called \emph{scalar replacement}. XXX check +whether that's true}. If some of the fields are themselves references to +allocation-removed objects they are recursively exploded +to make the vector contain only concrete variables. Some care has +to be taken to always place the fields in the same order when +performing this explosion. Notation becomes somewhat simpler if also every +concrete variable of the jump arguments is exploded into a vector containing +itself. For +every variable, $J_k$, of the original jump arguments, $J$, let +\begin{equation} + \tilde J^{\left(k\right)} = \left\{ + \begin{array}{ll} + \left(J_k\right) & \text{if $J_k$ is concrete} \\ + H^{\left(k\right)} & \text{if $J_k$ is allocation-removed} + \end{array} + \right. + , +\end{equation} +where $H^{\left(k\right)}$ is a vector containing all concrete +attributes of $J_k$. The arguments of the optimized \lstinline{jump} +operation are constructed as the concatenation all the $\tilde J^{\left(k\right)}$ vectors, +\begin{equation} + \hat J = \left( + \begin{array}{cccc} + \tilde J^{\left(1\right)} & \tilde J^{\left(2\right)} & \cdots & + \tilde J^{\left(|J|\right)} \\ + \end{array} + \right) + . +\end{equation} +The arguments of the \lstinline{jump} operation of the peeled loop, +$K$, is constructed by inlining $\hat J$, +\begin{equation} + \hat K = \left(m\left(\hat J_1\right), m\left(\hat J_1\right), + \cdots, m\left(\hat J_{|\hat J|}\right)\right) + . +\end{equation} +In the optimized trace $I$ is replaced by $\hat I$ and $K$ by $\hat +K$. The trace from Figure~\ref{fig:unopt-trace} will be optimized into + +\begin{lstlisting}[mathescape,numbers = right,basicstyle=\setstretch{1.05}\ttfamily\scriptsize] +$L_0$($p_{0}$, $p_{1}$): +# inside f: y = y.add(step) +guard_class($p_{1}$, BoxedInteger) + # inside BoxedInteger.add + $i_{2}$ = get($p_{1}$, intval) + guard_class($p_{0}$, BoxedInteger) + # inside BoxedInteger.add__int + $i_{3}$ = get($p_{0}$, intval) + $i_{4}$ = $i_{2}+i_{3}$ + # inside BoxedInteger.__init__ +jump($L_1$, $p_{0}$, $i_{4}$) + +$L_1$($p_{0}$, $i_{4}$): +# inside f: y = y.add(step) + # inside BoxedInteger.add + guard_class($p_{0}$, BoxedInteger) + # inside BoxedInteger.add__int + $i_{7}$ = get($p_{0}$, intval) + $i_{8}$ = $i_{4}+i_{7}$ + # inside BoxedInteger.__init__ +jump($L_1$, $p_{0}$, $i_8$) +\end{lstlisting} + +If all the optimizations presented above are applied, the resulting +optimized peeled loop will consist of a single integer addition +only. That is it will become type-specialized to the types of the +variables \lstinline{step} and \lstinline{y}, and the overhead of +using boxed values is removed. + +\section{Benchmarks} + +The loop peeling optimization was implemented in the PyPy +framework in about 450 lines of RPython code. That means that the JIT-compilers generated for all +interpreters implemented within PyPy now can take advantage of +it. Benchmarks have been executed for a few different interpreters and +we see improvements in several cases. The ideal loop for this optimization +would be short numerical calculations with no failing guards and no +external calls. Larger loops involving many operations on complex objects +typically benefit less from it. Loop peeling never makes runtime performance worse, in +the worst case the peeled loop is exactly the same as the preamble. Therefore we +chose to present benchmarks of small numeric kernels where loop peeling can show +its use. + +\begin{figure} +\begin{center} +{\smaller +\begin{tabular}{|l|r|r|r|r|r|r|} +\hline + & CPython & Psyco & PyPy & PyPy & GCC \\ + & & & no LP & & -O3 \\ +\hline +conv3(1e5) & 77.89 & 9.52 & 1.77 & 0.68 & 0.59 \\ +\hline +conv3(1e6) & 77.15 & 9.58 & 1.69 & 0.77 & 0.74 \\ +\hline +conv3x3(1000) & 233.54 & 125.40 & 0.57 & 0.27 & 0.25 \\ +\hline +conv3x3(3) & 234.45 & 126.28 & 0.60 & 0.31 & 0.28 \\ +\hline +conv5(1e5) & 122.54 & 16.67 & 1.86 & 1.05 & 0.65\\ +\hline +conv5(1e6) & 125.77 & 16.80 & 1.92 & 1.09 & 0.80 \\ +\hline +dilate3x3(1000) & 232.51 & 125.85 & 3.89 & 3.69 & 0.25 \\ +\hline +sobel(1000) & 181.49 & 95.05 & 0.71 & 0.42 & 0.20 \\ +\hline +sqrt(Fix16) & 744.35 & 421.65 & 3.93 & 2.14 & 0.96 \\ +\hline +sqrt(float) & 24.21 & 5.52 & 1.36 & 1.00 & 0.98\\ +\hline +sqrt(int) & 20.84 & 1.78 & 2.26 & 1.82 & 0.80 \\ +\hline +\hline +Variations & - & - & $\pm 0.03$ & $\pm 0.01$ & $\pm 0.01$ \\ +\hline +\end{tabular} +} +\end{center} +\label{fig:benchmarks} +\caption{Benchmark Results in Seconds.

A set of numerical +calculations were implemented in both Python and in C and their +runtimes are compared in Figure~\ref{fig:benchmarks}. The benchmarks are +\begin{itemize} +\item {\bf sqrt}: approximates the square root of $y$ as $x_\infty$ + with $x_0=y/2$ and $x_k = \left( x_{k-1} + y/x_{k-1} \right) / + 2$. There are three different versions of this benchmark where $x_k$ + is represented with different type of objects: int's, float's and + Fix16's. The latter, Fix16, is a custom class that implements + fixpoint arithmetic with 16 bits precision. In Python there is only + a single implementation of the benchmark that gets specialized + depending on the class of it's input argument, $y$, while in C, + there are three different implementations. +\item {\bf conv3}: one-dimensional convolution with fixed kernel-size $3$. +\item {\bf conv5}: one-dimensional convolution with fixed kernel-size $5$. +\item {\bf conv3x3}: two-dimensional convolution with kernel of fixed + size $3 \times 3$ using a custom class to represent two-dimensional + arrays. +\item {\bf dilate3x3}: two-dimensional dilation with kernel of fixed + size $3 \times 3$. This is similar to convolution but instead of + summing over the elements, the maximum is taken. That places a + external call to a max function within the loop that prevents some + of the optimizations. +\item {\bf sobel}: a low-level video processing algorithm used to + locate edges in an image. It calculates the gradient magnitude + using sobel derivatives. +\end{itemize} + +The sobel and conv3x3 benchmarks are implemented +on top of a custom two-dimensional array class. +It is +a simple straight forward implementation providing 2 dimensionall +indexing with out of bounds checks. For the C implementations it is +implemented as a C++ class. The other benchmarks are implemented in +plain C. + +Benchmarks were run on Intel i7 M620 @2.67GHz with 4M cache and 8G of RAM in +32bit mode. +The machine was otherwise unoccupied. We use the following software +for benchmarks: + +\begin{itemize} +\item PyPy 1.5 +\item CPython 2.7.2 +\item Psyco 1.6 with CPython 2.6.6 +\item GCC 4.4.5 shipped with Ubuntu 11.4 +\end{itemize} + +We run GCC both with -O2 optimization and -O3 -march=native, disabling the +automatic loop vectorization. In all cases, SSE2 instructions were used for +floating point operations, except Psyco which uses x87 FPU instructions. +We also run PyPy with loop peeling optimization and without (but otherwise +identical). + +For PyPy 10 iterations were run, prefaced with 3 iterations for warming up. +Due to benchmarks taking large amounts of time on CPython, only one run +was performed, prefaced with one warmup run for Psyco. +For GCC 5 iterations +were run. In all cases, the standard deviation is very low, making benchmarks +very well reproducible. + +We can observe that PyPy (even without loop peeling) is orders of magnitude +faster than either CPython or Psyco. This is due to the JIT compilation +advantages and optimizations we discussed in XXX [ref to other paper]. Loop +peeling gives an additional XXX on average, which makes benchmark times +comparable with native-compiled C code. Missing performance we attribute to +the relative immaturity of PyPy's JIT assembler backend as well as missing +optimizations, like instruction scheduling. + +Other interesting interpreters that are helped greatly by this +optimization are for +example our Prolog interpreter written in RPython, as well as numerical +kernel used for array manipulation. The exact extent is out of scope for +this paper. + +\section{Related Work} +\label{sec:related} + +All the optimizations presented here are completely standard +\cite{muchnick_advanced_1997}. XXX + +Mike Pall, the author of LuaJIT\footnote{\texttt{http://luajit.org/}} seems to +have developped the described technique independently. There are no papers about +LuaJIT but the author of it writes on a mailing list: "The LOOP pass does +synthetic unrolling of the recorded IR, combining copy-substitution with +redundancy elimination to achieve code hoisting. The unrolled and +copy-substituted instructions are simply fed back into the compiler pipeline, +which allows reuse of all optimizations for redundancy elimination. Loop +recurrences are detected on-the-fly and a minimized set of PHIs is generated." +\cite{pall_luajit_2009} + +SPUR \cite{bebenita_spur:_2010} implements loop-invariant code motion +directly, by explicitly marking as loop-invariant all variables that stay the +same along all looping paths and then moving all pure computation that depends +only on these variables out of the loop. SPUR can also hoist loads out of the +loop if nothing in the loop can ever write to the memory location. It can also +move allocations out of the loop, but does not replace the object by its fields. +This saves only the allocation, not the access to the object fields. + + +XXX +% section Related Work (end) + +\section{Conclusions} + +In this paper we have studied loop invariant code motion during trace +compilation. We claim that loop peeling is a very convenient solution +here since it fits well with other trace optimizations and does not require +large changes to them. This approach improves the effect of standard +optimizations such as redundant guard removal, common subexpression elimination +and allocation removal. The most prominent effect is that they all become loop +invariant code motion optimizations. + +By using several benchmarks we show that the proposed algorithm can +significantly improve the run time of small loops containing numerical +calculations. + +The current approach still has some limitations which we plan to address in the +future. In particular loop peeling works poorly in combination with trace +trees or trace stitching. The side exits attached guards that fail often +currently have to jump to the preamble which makes loops with several equally +common paths less efficient than they could be. + +%\appendix +%\section{Appendix Title} + +%This is the text of the appendix, if you need one. + +\acks + +Acknowledgments, if needed. + +% We recommend abbrvnat bibliography style. + +\bibliographystyle{abbrv} +\bibliography{paper} + +\end{document} diff --git a/talk/iwtc11/sigplanconf.cls b/talk/iwtc11/sigplanconf.cls new file mode 100644 --- /dev/null +++ b/talk/iwtc11/sigplanconf.cls @@ -0,0 +1,1251 @@ +%----------------------------------------------------------------------------- +% +% LaTeX Class/Style File +% +% Name: sigplanconf.cls +% Purpose: A LaTeX 2e class file for SIGPLAN conference proceedings. +% This class file supercedes acm_proc_article-sp, +% sig-alternate, and sigplan-proc. +% +% Author: Paul C.

Jython works by very carefully adding locks to +all the mutable built-in types, and by relying on the underlying Java +platform to be efficient about them (so that the result is faster than, +say, very carefully adding similar locks in CPython). By "very +carefully", I mean really really carefully; for example, +'dict1.update(dict2)' needs to lock both dict1 and dict2, but if you do +it naively, then a parallel 'dict2.update(dict1)' might cause a +deadlock. + +We are considering a quite different approach, based on `Software +Transactional Memory`_. This is a recent development in computer +science, and it gives a nicer solution than locking. Here is a short +introduction to it. + +Say you want to atomically pop an item from 'list1' and append it to +'list2':: + + def f(list1, list2): + x = list1.pop() + list2.append(x) + +This is not safe in multithreaded cases (even with the GIL). Say that +you call ``f(l1, l2)`` in thread 1 and ``f(l2, l1)`` in thread 2. What +you want is that it has no effect at all (x is moved from one list to +the other, then back). But what can occur is that instead the top of +the two lists are swapped, depending on timing issues. + +One way to fix it is with a global lock:: + + def f(list1, list2): + global_lock.acquire() + x = list1.pop() + list2.append(x) + global_lock.release() + +A finer way to fix it is with locks that come with the lists:: + + def f(list1, list2): + acquire_all_locks(list1.lock, list2.lock) + x = list1.pop() + list2.append(x) + release_all_locks(list1.lock, list2.lock) + +The second solution is a model for Jython's, while the first is a model +for CPython's. Indeed, in CPython's interpreter, we acquire the GIL, +then we do one bytecode (or actually a number of them, like 100), then +we release the GIL; and then we proceed to the next bunch of 100. + +Software Transactional Memory (STM) gives a third solution:: + + def f(list1, list2): + while True: + t = transaction() + x = list1.pop(t) + list2.append(t, x) + if t.commit(): + break + +In this solution, we make a ``transaction`` object and use it in all +reads and writes we do to the lists. There are actually several +different models, but let's focus on one of them. During a transaction, +we don't actually change the global memory at all. Instead, we use the +thread-local ``transaction`` object. We store in it which objects we +read from, which objects we write to, and what values we write. It is +only when the transaction reaches its end that we attempt to "commit" +it. Committing might fail if other commits have occurred inbetween, +creating inconsistencies; in that case, the transaction aborts and +must restart from the beginning. + +In the same way as the previous two solutions are models for CPython and +Jython, the STM solution looks like it could be a model for PyPy in the +future. In such a PyPy, the interpreter would start a transaction, do +one or several bytecodes, and then end the transaction; and repeat. +This is very similar to what is going on in CPython with the GIL. In +particular, it means that it gives programmers all the same guarantees +as the GIL does. The *only* difference is that it can actually run +multiple threads in parallel, as long as their code are not interfering +with each other. + +Why not apply that idea to CPython? Because we would need to change +everything everywhere. In the example above, you may have noted that I +no longer call 'list1.pop()', but 'list1.pop(t)'; this is a way to tell +that the implementation of all the methods needs to be changed, in order +to do their work "transactionally". This means that instead of really +changing the global memory in which the list is stored, it must instead +record the change in the ``transation`` object. If our interpreter is +written in C, like CPython, then we need to write it explicitly +everywhere. If it is written instead in a higher-level language, like +PyPy, then we can add this behavior as translation rules, and apply it +automatically wherever it is necessary. + +A final note: as STM research is very recent (it started around 2003), +there are a number of variants around, and it's not clear yet which one +is better in which cases. As far as I can tell, the approach described +in "A Comprehensive Strategy for Contention Management in Software +Transactional Memory" seems to be one possible state-of-the-art; it also +seems to be "good enough for all cases". + +So, when will it be done? No clue so far.
