+PyPy's JIT and Numpy
+====================
+
+Common problem when developing scientific application is that CPython's
+interpreter is too slow. This can mitigated by usage of FORTRAN, C or Cython
+in performance-critical parts of the code, but it would be much nicer
+to just run python faster.
+
+JIT was one of the main objectives of PyPy project for quite a while now.
+As of `March 2009`_ we're able to speed up simple examples in Python
+for about 20-30x over the speed of CPython. Since PyPy's JIT is much more
+flexible than for example Psyco, we expect even greater speedups in the
+future, as well as support for floats and 64bit architecture, which Psyco
+will not achieve in forseeable future.
+
+In this talk we would like to talk about PyPy's JIT, design principles and
+it's future, without going into too many architectural details.
+
+We would also like to present how JIT can make the life easier of simple
+postprocessing of data generated by EULAG model. XXX extend.
