Performance analysis tools for JITted VMs

+
+
+

Who am I?

+
    +
  • worked on PyPy for 5+ years
    • +
  • often presented with a task "my program runs slow"
    • +
  • never completely satisfied with present solutions
    • +
  • I'm not antisocial, just shy
    • +
+
+
+

The talk

+
    +
  • apologies for a lack of advanced warning - this is a rant
    • +
    +
  • I'll talk about tools
    • +
  • primarily profiling tools
    • +
    +
    +
  • lots of questions
    • +
  • not that many answers
    • +
    +
+
+
+

Why ranting?

+
    +
  • the topic at hand is hard
    • +
  • the mindset about tools is very much rooted in the static land
    • +
+
+
+

Profiling theory

+
    +
  • you spend 90% of your time in 10% of the functions
    • +
  • hence you can start profiling after you're done developing
    • +
  • by optimizing few functions
    • +
    +
  • problem - 10% of 600k lines is still 60k lines
    • +
  • that might be even 1000s of functions
    • +
    +
+
+
+

Let's talk about profiling

+
    +
  • I'll try profiling!
    • +
+
+
+

JITted landscape

+
    +
  • you have to account for warmup times
    • +
  • time spent in functions is very context dependent
    • +
+
+
+

Let's try!

+
+
+

High level languages

+
    +
  • in C relation C <-> assembler is "trivial"
    • +
  • in PyPy, V8 (JS) or luajit (lua), the mapping is far from trivial
    • +
    +
  • multiple versions of the same code
    • +
  • bridges even if there is no branch in user code
    • +
    +
  • sometimes I have absolutely no clue
    • +
+
+
+

The problem

+
    +
  • what I've shown is pretty much the state of the art
    • +
+
+
+

Another problem

+
    +
  • often when presented with profiling, it's already too late
    • +
+
+
+

Better tools

+
    +
  • good vm-level instrumentation
    • +
  • better visualizations, more code oriented
    • +
  • hints at the editor level about your code
    • +
  • hints about coverage, tests
    • +
+
+
+

</rant>

+
    +
  • good part - there are people working on it
    • +
  • questions, suggestions?

Performance analysis tools for JITted VMs

+
+
+

Who am I?

+
    +
  • worked on PyPy for 5+ years
    • +
  • often presented with a task "my program runs slow"
    • +
  • never completely satisfied with present solutions
    • +
  • I'm not antisocial, just shy
    • +
+
+
+

The talk

+
    +
  • apologies for a lack of advanced warning - this is a rant
    • +
    +
  • I'll talk about tools
    • +
  • primarily profiling tools
    • +
    +
    +
  • lots of questions
    • +
  • not that many answers
    • +
    +
+
+
+

Why ranting?

+
    +
  • the topic at hand is hard
    • +
  • the mindset about tools is very much rooted in the static land
    • +
+
+
+

Profiling theory

+
    +
  • you spend 90% of your time in 10% of the functions
    • +
  • hence you can start profiling after you're done developing
    • +
  • by optimizing few functions
    • +
    +
  • problem - 10% of 600k lines is still 60k lines
    • +
  • that might be even 1000s of functions
    • +
    +
+
+
+

Let's talk about profiling

+
    +
  • I'll try profiling!
    • +
+
+
+

JITted landscape

+
    +
  • you have to account for warmup times
    • +
  • time spent in functions is very context dependent
    • +
+
+
+

Let's try!

+
+
+

High level languages

+
    +
  • in C relation C <-> assembler is "trivial"
    • +
  • in PyPy, V8 (JS) or luajit (lua), the mapping is far from trivial
    • +
    +
  • multiple versions of the same code
    • +
  • bridges even if there is no branch in user code
    • +
    +
  • sometimes I have absolutely no clue
    • +
+
+
+

The problem

+
    +
  • what I've shown is pretty much the state of the art
    • +
+
+
+

Another problem

+
    +
  • often when presented with profiling, it's already too late
    • +
+
+
+

Better tools

+
    +
  • good vm-level instrumentation
    • +
  • better visualizations, more code oriented
    • +
  • hints at the editor level about your code
    • +
  • hints about coverage, tests
    • +
+
+
+

</rant>

+
    +
  • good part - there are people working on it
    • +
  • questions, suggestions?

Performance analysis tools for JITted VMs

+
+
+

Who am I?

+
    +
  • worked on PyPy for 5+ years
    • +
  • often presented with a task "my program runs slow"
    • +
  • never completely satisfied with present solutions
    • +
  • I'm not antisocial, just shy
    • +
+
+
+

The talk

+
    +
  • apologies for a lack of advanced warning - this is a rant
    • +
    +
  • I'll talk about tools
    • +
  • primarily profiling tools
    • +
    +
    +
  • lots of questions
    • +
  • not that many answers
    • +
    +
+
+
+

Why ranting?

+
    +
  • the topic at hand is hard
    • +
  • the mindset about tools is very much rooted in the static land
    • +
+
+
+

Profiling theory

+
    +
  • you spend 90% of your time in 10% of the functions
    • +
  • hence you can start profiling after you're done developing
    • +
  • by optimizing few functions
    • +
    +
  • problem - 10% of 600k lines is still 60k lines
    • +
  • that might be even 1000s of functions
    • +
    +
+
+
+

Let's talk about profiling

+
    +
  • I'll try profiling!
    • +
+
+
+

JITted landscape

+
    +
  • you have to account for warmup times
    • +
  • time spent in functions is very context dependent
    • +
+
+
+

Let's try!

+
+
+

High level languages

+
    +
  • in C relation C <-> assembler is "trivial"
    • +
  • in PyPy, V8 (JS) or luajit (lua), the mapping is far from trivial
    • +
    +
  • multiple versions of the same code
    • +
  • bridges even if there is no branch in user code
    • +
    +
  • sometimes I have absolutely no clue
    • +
+
+
+

The problem

+
    +
  • what I've shown is pretty much the state of the art
    • +
+
+
+

Another problem

+
    +
  • often when presented with profiling, it's already too late
    • +
+
+
+

Better tools

+
    +
  • good vm-level instrumentation
    • +
  • better visualizations, more code oriented
    • +
  • hints at the editor level about your code
    • +
  • hints about coverage, tests
    • +
+
+
+

</rant>

+
    +
  • good part - there are people working on it
    • +
  • questions, suggestions?

PyPy is now a fully compatible +alternative implementation of the Python language, xxx mention speed. The +Implementation takes advantage of the language features provided by RPython +such as the provided tracing just-in-time compiler described below. + +RPython, the language and the toolset originally developed to implement the +Python interpreter have developed into a general environment for experimenting +and developing fast and maintainable dynamic language implementations. xxx Mention +the different language impls. + +RPython is built of two components, the language and the translation toolchain +used to transform RPython programs to executable units. The RPython language +is a statically typed object oriented high level language. The language provides +several features such as automatic memory management (aka. Garbage Collection) +and just-in-time compilation. When writing an interpreter using RPython the +programmer only has to write the interpreter for the language she is +implementing. The second RPython component, the translation toolchain, is used +to transform the program to a low level representations suited to be compiled +and run on one of the different supported target platforms/architectures such +as C, .NET and Java. During the transformation process +different low level aspects suited for the target environment are automatically +added to program such as (if needed) a garbage collector and with some hints +provided by the author a just-in-time compiler. + + + +\subsection{PyPy's Meta-Tracing JIT Compilers} +\label{sub:tracing} + + * Tracing JITs + * JIT Compiler + * describe the tracing jit stuff in pypy + * reference tracing the meta level paper for a high level description of what the JIT does + * JIT Architecture + * Explain the aspects of tracing and optimization + +%___________________________________________________________________________ + + +\section{Resume Data} +\label{sec:Resume Data} + +* High level handling of resumedata + * trade-off fast tracing v/s memory usage + * creation in the frontend + * optimization + * compression + * interaction with optimization + * tracing and attaching bridges and throwing away resume data + * compiling bridges + +% section Resume Data (end) + +\section{Guards in the Backend} +\label{sec:Guards in the Backend} + +* Low level handling of guards + * Fast guard checks v/s memory usage + * memory efficient encoding of low level resume data + * fast checks for guard conditions + * slow bail out + +% section Guards in the Backend (end) + +%___________________________________________________________________________ + + +\section{Evaluation} +\label{sec:evaluation} + +* Evaluation + * Measure guard memory consumption and machine code size + * Extrapolate memory consumption for guard other guard encodings + * compare to naive variant + * Measure how many guards survive optimization + * Measure the of guards and how many of these ever fail + +\section{Related Work} + + +\section{Conclusion} + + +\section*{Acknowledgements} + +\bibliographystyle{abbrv} +\bibliography{paper} + +\end{document} diff --git a/talk/vmil2012/sigplanconf.cls b/talk/vmil2012/sigplanconf.cls new file mode 100644 --- /dev/null +++ b/talk/vmil2012/sigplanconf.cls @@ -0,0 +1,1250 @@ +%----------------------------------------------------------------------------- +% +% 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.

Note that the list is +not exhaustive - in fact it does not contain all the areas that are covered +by funding, notably numpy, STM and py3k. -- iterators in RPython +Iterating in RPython +==================== -- continuelet-jit-2 +Right now code that has a loop in RPython can be surprised by receiving +an iterable it does not expect. This ends up with doing an unnecessary copy +(or two or three in corner cases), essentially forcing an iterator. +An example of such code would be:: -- dynamic-specialized-tuples + import itertools + ''.join(itertools.repeat('ss', 10000000)) -- tracing speed +Would take 4s on PyPy and .4s on CPython. That's absolutely unacceptable :-) -- bridges and hakan's work +More optimized frames and generators +==================================== -- GC pinning +Right now generator expressions and generators have to have full frames, +instead of optimized ones like in the case of python functions. This leads +to inefficiences. There is a plan to improve the situation on the +``continuelet-jit-2`` branch. ``-2`` in branch names means it's hard and +has been already tried unsuccessfully :-) -- kill multimethods +A bit by chance it would make stackless work with the JIT. Historically though, +the idea was to make stackless work with the JIT and later figured out this +could also be used for generators. Who would have thought :) +This work should allow to improve the situation of uninlined functions +as well. + +Dynamic specialized tuples and instances +======================================== + +PyPy already uses maps. Read our `blog`_ `posts`_ about details. However, +it's possible to go even further, by storing unboxed integers/floats +directly into the instance storage instead of having pointers to python +objects. This should improve memory efficiency and speed for the cases +where your instances have integer or float fields. + +Tracing speed +============= + +PyPy is probably one of the slowest compilers when it comes to warmup times. +There is no open branch, but we're definitely thinking about the problem :-) + +Bridge optimizations +==================== + +Another "area of interest" is bridge generation. Right now generating a bridge +from compiled loop "forgets" some kind of optimization information from the +loop. + +GC pinning and I/O performance +============================== +

Garbage Collection) +and just-in-time compilation. When writing an interpreter using RPython the +programmer only has to write the interpreter for the language she is +implementing. The second RPython component, the translation toolchain, is used +to transform the program to a low level representations suited to be compiled +and run on one of the different supported target platforms/architectures such +as C, .NET and Java. During the transformation process +different low level aspects suited for the target environment are automatically +added to program such as (if needed) a garbage collector and with some hints +provided by the author a just-in-time compiler. + + + \subsection{PyPy's Meta-Tracing JIT Compilers} \label{sub:tracing} @@ -134,7 +162,7 @@ * High level handling of resumedata * trade-off fast tracing v/s memory usage - * creation in the frontend + * creation in the frontend * optimization * compression * interaction with optimization From noreply at buildbot.pypy.org Wed Jul 4 22:10:24 2012 From: noreply at buildbot.pypy.org (mattip) Date: Wed, 4 Jul 2012 22:10:24 +0200 (CEST) Subject: [pypy-commit] pypy numpypy-argminmax: fix, add more passing tests Message-ID: <20120704201024.C97291C0185@cobra.cs.uni-duesseldorf.de> Author: mattip Branch: numpypy-argminmax Changeset: r55921:881739f5e4db Date: 2012-07-04 23:09 +0300 http://bitbucket.org/pypy/pypy/changeset/881739f5e4db/ Log: fix, add more passing tests diff --git a/pypy/module/micronumpy/interp_iter.py b/pypy/module/micronumpy/interp_iter.py --- a/pypy/module/micronumpy/interp_iter.py +++ b/pypy/module/micronumpy/interp_iter.py @@ -379,4 +379,4 @@ self.done = True def get_dim_index(self): - return self.indices[0] + return self.indices[self.dimorder[0]] diff --git a/pypy/module/micronumpy/interp_numarray.py b/pypy/module/micronumpy/interp_numarray.py --- a/pypy/module/micronumpy/interp_numarray.py +++ b/pypy/module/micronumpy/interp_numarray.py @@ -224,6 +224,9 @@ return out return Scalar(res_dtype, res_dtype.box(result)) def do_axisminmax(self, space, axis, out): + # Use a AxisFirstIterator to walk along self, with dimensions + # reordered to move along 'axis' fastest.

Performance analysis tools for JITted VMs

+
+
+

Who am I?

+
    +
  • worked on PyPy for 5+ years
    • +
  • often presented with a task "my program runs slow"
    • +
  • never completely satisfied with present solutions
    • +
  • I'm not antisocial, just shy
    • +
+
+
+

The talk

+
    +
  • apologies for a lack of advanced warning - this is a rant
    • +
    +
  • I'll talk about tools
    • +
  • primarily profiling tools
    • +
    +
    +
  • lots of questions
    • +
  • not that many answers
    • +
    +
+
+
+

Why ranting?

+
    +
  • the topic at hand is hard
    • +
  • the mindset about tools is very much rooted in the static land
    • +
+
+
+

Profiling theory

+
    +
  • you spend 90% of your time in 10% of the functions
    • +
  • hence you can start profiling after you're done developing
    • +
  • by optimizing few functions
    • +
    +
  • problem - 10% of 600k lines is still 60k lines
    • +
  • that might be even 1000s of functions
    • +
    +
+
+
+

Let's talk about profiling

+
    +
  • I'll try profiling!
    • +
+
+
+

JITted landscape

+
    +
  • you have to account for warmup times
    • +
  • time spent in functions is very context dependent
    • +
+
+
+

Let's try!

+
+
+

High level languages

+
    +
  • in C relation C <-> assembler is "trivial"
    • +
  • in PyPy, V8 (JS) or luajit (lua), the mapping is far from trivial
    • +
    +
  • multiple versions of the same code
    • +
  • bridges even if there is no branch in user code
    • +
    +
  • sometimes I have absolutely no clue
    • +
+
+
+

The problem

+
    +
  • what I've shown is pretty much the state of the art
    • +
+
+
+

Another problem

+
    +
  • often when presented with profiling, it's already too late
    • +
+
+
+

Better tools

+
    +
  • good vm-level instrumentation
    • +
  • better visualizations, more code oriented
    • +
  • hints at the editor level about your code
    • +
  • hints about coverage, tests
    • +
+
+
+

</rant>

+
    +
  • good part - there are people working on it
    • +
  • questions, suggestions?

The RPython language +is a statically typed object oriented high level language. The language provides +several features such as automatic memory management (aka. Garbage Collection) +and just-in-time compilation. When writing an interpreter using RPython the +programmer only has to write the interpreter for the language she is +implementing. The second RPython component, the translation toolchain, is used +to transform the program to a low level representations suited to be compiled +and run on one of the different supported target platforms/architectures such +as C, .NET and Java.

In particular, whenever we try to encode a 8-bit string into an +unicode, PyPy asks the ``_codecs`` built-in module to find the suitable +codec. Then, ``_codecs`` tries to import the ``encodings`` package, to list +all the available encodings. ``encodings`` is a package of the standard +library written in pure Python, so it is located inside +``lib-python/3.2``. But at this point in time we yet have to add +``lib-python/3.2`` to ``sys.path``, so the import fails. Bootstrap problem! + +The hard part was to find the problem: since it is an error which happens so +early, the interpreter is not even able to display a traceback, because it +cannot yet import ``traceback.py``. The only way to debug it was through some +carefully placed ``print`` statement and the help of ``gdb``. Once found the +problem, the solution was as easy as moving part of the logic to RPython, +where we don't have bootstrap problems. + +Once the problem was fixed, I was able to finally run all the CPython test +against the compiled PyPy.

It is a summary of the +keynote presentation at EuroPython. As I learned by talking with people +afterwards, I am not a good enough speaker to manage to convey a deeper +message in a 20-minutes talk. I will try instead to convey it in a +150-lines post :-) + +This is fundamentally about three points, which can be summarized as +follow: + +1. We often hear about people wanting a version of Python running without + the Global Interpreter Lock (GIL): a "GIL-less Python". But what we + programmers really need is not just a GIL-less Python --- it is a + higher-level way to write multithreaded programs. This can be + achieved with Automatic Mutual Exclusion (AME): an "AME Python". + +2. A good enough Software Transactional Memory (STM) system can do that. + This is what we are building into PyPy: an "AME PyPy". + +3. The picture is darker for CPython. The only viable solutions there + are GCC's STM support, or Hardware Transactional Memory (HTM). + However, both solutions are enough for a "GIL-less CPython", but not + for "AME CPython", due to capacity limitations. + +Before we come to conclusions, let me explain these points in more +details. + + +GIL-less versus AME +------------------- + +The first point is in favor of the so-called Automatic Mutual Exclusion +approach. The issue with using threads (in any language with or without +a GIL) is that threads are fundamentally non-deterministic. In other +words, the programs' behavior is not reproductible at all, and worse, we +cannot even reason about it --- it becomes quickly messy. We would have +to consider all possible combinations of code paths and timings, and we +cannot hope to write tests that cover all combinations. This fact is +often documented as one of the main blockers towards writing successful +multithreaded applications. + +We need to solve this issue with a higher-level solution. Such +solutions exist theoretically, and Automatic Mutual Exclusion is one of +them. The idea is that we divide the execution of each thread into some +number of large, well-delimited blocks. Then we use internally a +technique that lets the interpreter run the threads in parallel, while +giving the programmer the illusion that the blocks have been run in some +global serialized order. + + +PyPy and STM +------------ + +Talking more precisely about PyPy: the current prototype ``pypy-stm`` is +doing precisely this. The length of the "blocks" above is selected in +one of two ways: either we have blocks corresponding to some small +number of bytecodes (in which case we have merely a GIL-less Python); or +we have blocks that are specified explicitly by the programmer using +``with thread.atomic:``. The latter gives typically long-running +blocks. It allows us to build the higher-level solution sought after: +we will run most of our Python code in multiple threads but always +within a ``thread.atomic``. + +This gives the nice illusion of a global serialized order, and thus +gives us a well-behaving model of our program's behavior. Of course, it +is not the perfect solution to all troubles: notably, we have to detect +and locate places that cause too many "conflicts" in the Transactional +Memory sense. A conflict causes the execution of one block of code to +be aborted and restarted. Although the process is transparent, if it +occurs more than occasionally, then it has a negative impact on +performance. We will need better tools to deal with them. The point +here is that at all stages our program is *correct*, while it may not be +as efficient as it could be. This is the opposite of regular +multithreading, where programs are efficient but not as correct as they +could be... + + +CPython and HTM +--------------- + +Couldn't we do the same for CPython? The problem here is that we would +need to change literally all places of the CPython C sources in order to +implement STM. Assuming that this is far too big for anyone to handle, +we are left with two other options: + +- We could use GCC 4.7, which supports some form of STM. + +- We wait until Intel's next generation of CPUs comes out ("Haswell") + and use HTM. + +The issue with each of these two solutions is the same: they are meant +to support small-scale transactions, but not long-running ones. For +example, I have no clue how to give GCC rules about performing I/O in a +transaction; and moreover looking at the STM library that is available +so far to be linked with the compiled program, it assumes short +transactions only. + +Intel's HTM solution is both more flexible and more strictly limited. +In one word, the transaction boundaries are given by a pair of special +CPU instructions that make the CPU enter or leave "transactional" mode. +If the transaction aborts, the CPU rolls back to the "enter" instruction +(like a ``fork()``) and causes this instruction to return an error code +instead of re-entering transactional mode. The software then detects +the error code; typically, if only a few transactions end up being too +long, it is fine to fall back to a GIL-like solution just to do these +transactions. + +This is all implemented by keeping all changes to memory inside the CPU +cache, invisible to other cores; rolling back is then just a matter of +discarding a part of this cache without committing it to memory. From +this point of view, there is a lot to bet that this cache is actually +the regular per-core Level 1 cache --- any transaction that cannot fully +store its read and written data in the 32-64KB of the L1 cache will +abort. + +So what does it mean? A Python interpreter overflows the L1 cache of +the CPU almost instantly: just creating new frames takes a lot of memory +(the order of magnitude is below 100 function calls). This means that +as long as the HTM support is limited to L1 caches, it is not going to +be enough to run an "AME Python" with any sort of medium-to-long +transaction. It can run a "GIL-less Python", though: just running a few +bytecodes at a time should fit in the L1 cache, for most bytecodes. + + +Conclusion? +----------- + +Even if we assume that the arguments at the top of this post are valid, +there is more than one possible conclusion we can draw. My personal +pick in the order of likeliness would be: people might continue to work +in Python avoiding multiple threads, even with a GIL-less interpreter; +or they might embrace multithreaded code and some half-reasonable tools +and practices might emerge; or people will move away from Python in +favor of a better suited language; or finally people will completely +abandon CPython in favor of PyPy (but somehow I doubt it :-) + +I will leave the conclusions open, as it basically depends on a language +design issue and so not my strong point. But if I can point out one +thing, it is that the ``python-dev`` list should discuss this issue +sooner rather than later.

However, in PyPy we cannot simply move them to builtins, because they are needed in the early bootstrap of the space, before builtins is initialized. So, we keep them in a separate module (renamed to '__exceptions__' because it's an internal implementation detail only) but we pretend that its __module__ is 'builtins'. This approach has the extra bonus that it minimizes the divergence from default. diff --git a/pypy/interpreter/baseobjspace.py b/pypy/interpreter/baseobjspace.py --- a/pypy/interpreter/baseobjspace.py +++ b/pypy/interpreter/baseobjspace.py @@ -503,7 +503,7 @@ "NOT_RPYTHON: only for initializing the space." from pypy.module.exceptions import Module -

This includes new + functionality to test the validity of file descriptors; and + correct handling of the calling convensions for ctypes. (Still not + much progress on Win64.) A lot of work on this has been done by Matti Picus + and Amaury Forgeot d'Arc. + +* Improvements in ``cpyext``, our emulator for CPython C extension modules. + For example PyOpenSSL should now work. We thank various people for help. + +* Sets now have strategies just like dictionaries. This means for example + that a set containing only ints will be more compact (and faster). + +* A lot of progress on various aspects of ``numpypy``. See the `numpy-status`_ + page for the automatic report. + +* It is now possible to create and manipulate C-like structures using the + PyPy-only ``_ffi`` module. The advantage over using e.g. ``ctypes`` is that + ``_ffi`` is very JIT-friendly, and getting/setting of fields is translated + to few assembler instructions by the JIT. However, this is mostly intended + as a low-level backend to be used by more user-friendly FFI packages, and + the API might change in the future. Use it at your own risk. + +* The non-x86 backends for the JIT are progressing but are still not + merged (ARMv7 and PPC64). + +* JIT hooks for inspecting the created assembler code have been improved. + See `JIT hooks documentation`_ for details. + +* ``select.kqueue`` has been added (BSD). + +* Handling of keyword arguments has been drastically improved in the best-case + scenario: proxy functions which simply forwards ``*args`` and ``**kwargs`` + to another function now performs much better with the JIT. + +* List comprehension has been improved. + +.. _`numpy-status`: http://buildbot.pypy.org/numpy-status/latest.html +.. _`JIT hooks documentation`: http://doc.pypy.org/en/latest/jit-hooks.html + +JitViewer +========= + +There will be a corresponding 1.9 release of JitViewer which is guaranteed +to work with PyPy 1.9.

During the forward pass IR-level variables are +assigned to registers and stack locations by the register allocator according to +the requirements of the to be emitted instructions. Eviction/spilling is +performed based on the live range information collected in the first pass.

When a guard is compiled, additionally to the +condition check two things are generated/compiled. First a special +data structure is created that encodes the information provided by the register +allocator about where the values corresponding to each IR-variable required by +the guard will be stored when execution reaches the code emitted for the +corresponding guard. \bivab{go into more detail here?!} This encoding needs to +be as compact as possible to maintain an acceptable memory profile. + +\bivab{example goes here} + +Second a trampoline method stub is generated.

Moreover, it is forbidden + to mix unicode and strings when formatting. **tuples** diff --git a/pypy/objspace/std/strutil.py b/pypy/objspace/std/strutil.py --- a/pypy/objspace/std/strutil.py +++ b/pypy/objspace/std/strutil.py @@ -193,4 +193,4 @@ try: return rstring_to_float(mystring) except ValueError: - raise ParseStringError(u"invalid literal for float()") + raise ParseStringError(u"invalid literal for float(): '%s'" % s) diff --git a/pypy/objspace/std/test/test_floatobject.py b/pypy/objspace/std/test/test_floatobject.py --- a/pypy/objspace/std/test/test_floatobject.py +++ b/pypy/objspace/std/test/test_floatobject.py @@ -441,6 +441,14 @@ b = A(5).real assert type(b) is float + def test_invalid_literal_message(self): + try: + float('abcdef') + except ValueError as e: + assert 'abcdef' in e.message + else: + assert False, 'did not raise' + def test_float_from_unicode(self): s = '\U0001D7CF\U0001D7CE.4' # 𝟏𝟎.4 assert float(s) == 10.4 diff --git a/pypy/rlib/objectmodel.py b/pypy/rlib/objectmodel.py --- a/pypy/rlib/objectmodel.py +++ b/pypy/rlib/objectmodel.py @@ -112,7 +112,9 @@ """ Decorate a function with forcing of RPython-level types on arguments.

Moreover, it is forbidden + to mix unicode and strings when formatting. **tuples** diff --git a/pypy/doc/whatsnew-head.rst b/pypy/doc/whatsnew-head.rst --- a/pypy/doc/whatsnew-head.rst +++ b/pypy/doc/whatsnew-head.rst @@ -14,5 +14,12 @@ .. branch: nupypy-axis-arg-check Check that axis arg is valid in _numpypy +.. branch: iterator-in-rpython +.. branch: numpypy_count_nonzero +.. branch: even-more-jit-hooks +Implement better JIT hooks + ..

following one concrete execution, +not the full control flow of a program is observed. +The possible points of deviation from the trace are guard operations +that check whether the same assumptions as during tracing still hold. +In later executions of the trace the guards can fail. +If that happens, execution needs to continue in the interpreter. +This means it is necessary to attach enough information to a guard +to construct the interpreter state when that guard fails. +This information is called the \emph{resume data}. + +To do this reconstruction, it is necessary to take the values +of the SSA variables of the trace +and build interpreter stack frames. +Tracing aggressively inlines functions. +Therefore the reconstructed state of the interpreter +can consist of several interpreter frames. + +If a guard fails often enough, a trace is started from it +to create a trace tree. +When that happens another use case of resume data +is to construct the tracer state. + +There are several forces guiding the design of resume data handling. +Guards are a very common operations in the traces. +However, a large percentage of all operations +are optimized away before code generation. +Since there are a lot of guards +the resume data needs to be stored in a very compact way. +On the other hand, tracing should be as fast as possible, +so the construction of resume data must not take too much time. + +\subsection{Capturing of Resume Data During Tracing} +\label{sub:capturing} + +Every time a guard is recorded during tracing +the tracer attaches preliminary resume data to it. +The data is preliminary in that it is not particularly compact yet. +The preliminary resume data takes the form of a stack of symbolic frames. +The stack contains only those interpreter frames seen by the tracer. +The frames are symbolic in that the local variables in the frames +do not contain values. +Instead, every local variables contains the SSA variable of the trace +where the value would later come from, or a constant. + +\subsection{Compression of Resume Data} +\label{sub:compression} + +The core idea of storing resume data as compactly as possible +is to share parts of the data structure between subsequent guards. +This is often useful because the density of guards in traces is so high, +that quite often not much changes between them. +Since resume data is a linked list of symbolic frames +often only the information in the top frame changes from one guard to the next. +The other frames can often be just reused. +The reason for this is that during tracing only the variables +of the currently executing frames can change. +Therefore if two guards are generated from code in the same function +the resume data of the rest of the stack can be reused. + +\subsection{Interaction With Optimization} +\label{sub:optimization} + +Guards interact with optimizations in various ways. +Most importantly optimizations try to remove as many operations +and therefore guards as possible. +This is done with many classical compiler optimizations. +In particular guards can be remove by subexpression elimination. +If the same guard is encountered a second time in the trace, +the second one can be removed. +This also works if a later guard is weaker implied by a earlier guard. + +One of the techniques in the optimizer specific to tracing for removing guards +is guard strengthening~\cite{bebenita_spur:_2010}. +The idea of guard strengthening is that if a later guard is stronger +than an earlier guard it makes sense to move the stronger guard +to the point of the earlier, weaker guard and to remove the weaker guard. +Moving a guard to an earlier point is always valid, +it just means that the guard fails earlier during the trace execution +(the other direction is clearly not valid). + +The other important point of interaction between resume data and the optimizer +is RPython's allocation removal optimization~\cite{bolz_allocation_2011}. +This optimization discovers allocations in the trace that create objects +that do not survive long. +An example is the instance of \lstinline{Even} in the example\cfbolz{reference figure}. +Allocation removal makes resume data more complex. +Since allocations are removed from the trace it becomes necessary +to reconstruct the objects that were not allocated so far when a guard fails. +Therefore the resume data needs to store enough information +to make this reconstruction possible. + +Adding this additional information is done as follows. +So far, every variable in the symbolic frames +contains a constant or an SSA variable. +After allocation removal the variables in the symbolic frames can also contain +``virtual'' objects. +These are objects that were not allocated so far, +because the optimizer removed their allocation. +The virtual objects in the symbolic frames describe exactly +how the heap objects that have to be allocated on guard failure look like. +To this end, the content of the every field of the virtual object is described +in the same way that the local variables of symbolic frames are described. +The fields of the virtual objects can therefore be SSA variables, constants +or other virtual objects. + +During the storing of resume data virtual objects are also shared +between subsequent guards as much as possible. +The same observation as about frames applies: +Quite often a virtual object does not change from one guard to the next. +Then the data structure is shared. + +% subsection Interaction With Optimization (end) + * High level

This branch improves the performance on most long operations and use 64bit storage and __int128 for wide digits on systems where it is available. Message-ID: <20120725004250.A50C31C0044@cobra.cs.uni-duesseldorf.de> Author: Stian Andreassen Branch: Changeset: r56444:8a78c6bf2abb Date: 2012-07-25 02:37 +0200 http://bitbucket.org/pypy/pypy/changeset/8a78c6bf2abb/ Log: Merge improve-rbigint. This branch improves the performance on most long operations and use 64bit storage and __int128 for wide digits on systems where it is available. Special cases for power of two mod, division, multiplication. Improvements to pow (see pypy/translator/goal/targetbigintbenchmark.py for some runs on my system), mark operations as elidable and various other tweaks. Overall, it makes things run faster than CPython if the script doesn't heavily rely on division. diff --git a/pypy/module/sys/system.py b/pypy/module/sys/system.py --- a/pypy/module/sys/system.py +++ b/pypy/module/sys/system.py @@ -48,8 +48,8 @@ def get_long_info(space): #assert rbigint.SHIFT == 31 - bits_per_digit = 31 #rbigint.SHIFT - sizeof_digit = rffi.sizeof(rffi.ULONG) + bits_per_digit = rbigint.SHIFT + sizeof_digit = rffi.sizeof(rbigint.STORE_TYPE) info_w = [ space.wrap(bits_per_digit), space.wrap(sizeof_digit), diff --git a/pypy/rlib/rarithmetic.py b/pypy/rlib/rarithmetic.py --- a/pypy/rlib/rarithmetic.py +++ b/pypy/rlib/rarithmetic.py @@ -115,21 +115,16 @@ n -= 2*LONG_TEST return int(n) -if LONG_BIT >= 64: - def longlongmask(n): - assert isinstance(n, (int, long)) - return int(n) -else: - def longlongmask(n): - """ - NOT_RPYTHON - """ - assert isinstance(n, (int, long)) - n = long(n) - n &= LONGLONG_MASK - if n >= LONGLONG_TEST: - n -= 2*LONGLONG_TEST - return r_longlong(n) +def longlongmask(n): + """ + NOT_RPYTHON + """ + assert isinstance(n, (int, long)) + n = long(n) + n &= LONGLONG_MASK + if n >= LONGLONG_TEST: + n -= 2*LONGLONG_TEST + return r_longlong(n) def longlonglongmask(n): # Assume longlonglong doesn't overflow.

The interface between the compiler and runtime system is a principal factor in the flexibility of both components and is critical to enabling rapid pursuit of new optimizations and features. Although many virtual machines have demonstrated modularity for many components, significant dependencies often remain between the compiler and the runtime system components such as the object model and memory management system. This paper addresses this challenge with a carefully designed strict compiler-runtime interface and the {XIR} language. Instead of the compiler backend lowering object operations to machine operations using hard-wired runtime-specific logic, {XIR} allows the runtime system to implement this logic, simultaneously simplifying and separating the backend from runtime-system details. In this paper we describe the design and implementation of this compiler-runtime interface and the {XIR} language in the {C1X} dynamic compiler, a port of the {HotSpotTM} Client compiler.

It was implemented for Sun Microsystems' Java {HotSpot™} client compiler and operates on an intermediate representation in {SSA} form. We introduce equi-escape sets for the efficient propagation of escape information between related objects. The analysis is used for scalar replacement of fields and synchronization removal, as well as for stack allocation of objects and fixed-sized arrays. The results of the interprocedural analysis support the compiler in inlining decisions and allow actual parameters to be allocated on the caller {stack.Under} certain circumstances, the Java {HotSpot™} {VM} is forced to stop executing a method's machine code and transfer control to the interpreter. This is called deoptimization.

This reduces the execution speed of Java programs. Array bounds check elimination identifies situations in which such checks are redundant and can be removed. We present an array bounds check elimination algorithm for the Java {HotSpot(TM)} {VM} based on static analysis in the just-in-time compiler. The algorithm works on an intermediate representation in static single assignment form and maintains conditions for index expressions. It fully removes bounds checks if it can be proven that they never fail. Whenever possible, it moves bounds checks out of loops. The static number of checks remains the same, but a check inside a loop is likely to be executed more often. If such a check fails, the executing program falls back to interpreted mode, avoiding the problem that an exception is thrown at the wrong place. The evaluation shows a speedup near to the theoretical maximum for the scientific {SciMark} benchmark suite and also significant improvements for some Java Grande benchmarks. The algorithm slightly increases the execution speed for the {SPECjvm98} benchmark suite.

It shields the debugger from optimizations performed by the compiler by dynamically deoptimizing code on demand. Deoptimization only affects the procedure activations that are actively being debugged; all other code runs at full speed. Deoptimization requires the compiler to supply debugging information at discrete interrupt points; the compiler can still perform extensive optimizations between interrupt points without affecting debuggability. At the same time, the inability to interrupt between interrupt points is invisible to the user. Our debugging system also handles programming changes during debugging. Again, the system provides expected behavior: it is possible to change a running program and immediately observe the effects of the change.

One crucial point is to unroll the bytecode dispatch loop, based on two kinds of hints provided by the implementer of the bytecode interpreter. We evaluate our technique by applying it to two {PyPy} interpreters: one is a small example, and the other one is the full Python interpreter.}, + booktitle = {{ICOOOLPS}}, + publisher = {{ACM}}, + author = {Bolz, Carl Friedrich and Cuni, Antonio and Fijałkowski, Maciej and Rigo, Armin}, + year = {2009}, + pages = {18--25} +}, + + at inproceedings{paleczny_java_2001, + address = {Monterey, California}, + title = {The Java {HotSpot} server compiler}, + url = {http://portal.acm.org/citation.cfm?id=1267848}, + abstract = {The Java {HotSpotTM} Server Compiler achieves improved asymptotic performance through a combination of object-oriented and classical-compiler optimizations.

Pure object-oriented languages are harder to implement efficiently since they need optimization to achieve good performance. Unfortunately, optimization conflicts with interactive responsiveness because it tends to produce long compilation pauses, leading to unresponsive programming environments. Therefore, to achieve good responsiveness, existing exploratory programming environments such as the Smalltalk-80 environment rely on interpretation or non-optimizing dynamic compilation. But such systems pay a price for their interactiveness, since they may execute programs several times slower than an optimizing {system.SELF-93} reconciles high performance with responsiveness by combining a fast, non-optimizing compiler with a slower, optimizing compiler. The resulting system achieves both excellent performance (two or three times faster than existing Smalltalk systems) and good responsiveness. Except for situations requiring large applications to be (re)compiled from scratch, the system allows for pleasant interactive use with few perceptible compilation pauses. To our knowledge, {SELF-93} is the first implementation of a pure object-oriented language achieving both good performance and good {responsiveness.When} measuring interactive pauses, it is imperative to treat multiple short pauses as one longer pause if the pauses occur in short succession, since they are perceived as one pause by the user. We propose a definition of pause clustering and show that clustering can make an order-of-magnitude difference in the pause time distribution.}, + number = {10}, + journal = {{SIGPLAN} Not.}, + author = {Hölzle, Urs and Ungar, David}, + year = {1994}, + keywords = {interactivity, recompilation, self}, + pages = {229--243} +} \ No newline at end of file From noreply at buildbot.pypy.org Thu Jul 26 11:14:05 2012 From: noreply at buildbot.pypy.org (cfbolz) Date: Thu, 26 Jul 2012 11:14:05 +0200 (CEST) Subject: [pypy-commit] extradoc extradoc: add citations Message-ID: <20120726091405.91FD81C002D@cobra.cs.uni-duesseldorf.de> Author: Carl Friedrich Bolz Branch: extradoc Changeset: r4368:654fd8bb94af Date: 2012-07-25 11:22 +0200 http://bitbucket.org/pypy/extradoc/changeset/654fd8bb94af/ Log: add citations diff --git a/talk/vmil2012/paper.tex b/talk/vmil2012/paper.tex --- a/talk/vmil2012/paper.tex +++ b/talk/vmil2012/paper.tex @@ -493,7 +493,7 @@ This is often the case when new code is added to the system, or when the programmer tries to debug the program. -Deutsch et. al.~\cite{XXX} describe the use of stack descriptions +Deutsch et. al.~\cite{deutsch_efficient_1984} describe the use of stack descriptions to make it possible to do source-level debugging of JIT-compiled code.

Pall also acknowledges that snapshot for +guards are associated with a large memory footprint. The solution used in +LuaJIT is to store sparse snapshots, avoiding the creation of snapshots for +every guard to reduce memory pressure.

Later this +was replaced by generting compensation code for each guard which produced a +lower overhead in their benchmarks. HotpathVM also records secondary traces +starting from failing guards that are connected directly to the original trace. +Secondary traces are compiled by first restoring the register allocator state to +the state at the side exit. The information is retrieved from a mapping stored +in the guard that maps machine level registers and stack to Java level stack +and variables. + +Gal et. al~\cite{Gal:2009ux} write about how TraceMonkey uses trace stitching +to avoid th overhead of returning to the trace monitor and calling another +trace when taking a side exit.

This includes new + functionality to test the validity of file descriptors; and + correct handling of the calling convensions for ctypes. (Still not + much progress on Win64.) A lot of work on this has been done by Matti Picus + and Amaury Forgeot d'Arc. + +* Improvements in ``cpyext``, our emulator for CPython C extension modules. + For example PyOpenSSL should now work. We thank various people for help. + +* Sets now have strategies just like dictionaries. This means for example + that a set containing only ints will be more compact (and faster). + +* A lot of progress on various aspects of ``numpypy``. See the `numpy-status`_ + page for the automatic report. + +* It is now possible to create and manipulate C-like structures using the + PyPy-only ``_ffi`` module. The advantage over using e.g. ``ctypes`` is that + ``_ffi`` is very JIT-friendly, and getting/setting of fields is translated + to few assembler instructions by the JIT. However, this is mostly intended + as a low-level backend to be used by more user-friendly FFI packages, and + the API might change in the future. Use it at your own risk. + +* The non-x86 backends for the JIT are progressing but are still not + merged (ARMv7 and PPC64). + +* JIT hooks for inspecting the created assembler code have been improved. + See `JIT hooks documentation`_ for details. + +* ``select.kqueue`` has been added (BSD). + +* Handling of keyword arguments has been drastically improved in the best-case + scenario: proxy functions which simply forwards ``*args`` and ``**kwargs`` + to another function now performs much better with the JIT. + +* List comprehension has been improved. + +.. _`numpy-status`: http://buildbot.pypy.org/numpy-status/latest.html +.. _`JIT hooks documentation`: http://doc.pypy.org/en/latest/jit-hooks.html + +JitViewer +========= + +There will be a corresponding 1.9 release of JitViewer which is guaranteed +to work with PyPy 1.9.
