use as benchmark pypy vs python if you please
by Dima Tisnek 13 Sep '15

13 Sep '15

Attached is n-queens solver (pardon my naive algorithm), it runs: python 2.7.6: 17s pypy 2.4.0 alpha: 23s same nojit: 32s I've tried similar-looking algorithm for another problem before, and has similar results -- somehow pypy was slower. feel free to investigate / tweak or even use on speed.pypy.org

Poor performance for Krakatau
by Robert Grosse 10 Aug '15

10 Aug '15

In some cases, Pypy performs worse than CPython when running Krakatau, and it has gotten a lot worse from 2.3 to 2.5 My benchmark is https://github.com/Storyyeller/Krakatau/tree/pypy_benchmark (for future reference, commit d889c7f44723e6d66a3630681f0385f173317dc9) You can run it with pypy Krakatau\benchmark.py -path <path to Java rt.jar> I get the following timings CPython: 17.43s Pypy 2.3: 38.48s (build pypy-c-jit-71056-c8e3b8cbc843-win32) Pypy 2.4: 39.92s (build pypy-c-jit-72200-375133966c12-win32) Pypy 2.5: 49.94s (build pypy-c-jit-74404-9fd586fe0fe5-win32) Not only was it slower than CPython to begin with, but it got much worse recently.

by Matti Picus 01 Jun '15

01 Jun '15

New release packages with cffi 1.1.0 are available on bitbucket , note these are different than what I sent out before. https://bitbucket.org/pypy/pypy/downloads Please try them out, we have new buildslaves for win32, macosx and linux64. We would especially appreciate testing out the vmprof profiling features available on linux-64 Comments on the release notice are also welcome, extra points for guessing what "Cameo Charm" means. No fair checking IRC logs for hints. http://pypy.readthedocs.org/en/release-2.6.x/release-2.6.0.html Matti

An overview of the RPython language
by Ryan Gonzalez 31 May '15

31 May '15

I wrote a quick overview of the RPython language at http://kirbyfan64.github.io/posts/the-magic-of-rpython.html. Any suggestions for improvement would be appreciated. :) IMO, this is needed. Most RPython articles are insanely old (from 200x) or just cover the JIT (Andrew Brown's excellent tutorial). -- Ryan [ERROR]: Your autotools build scripts are 200 lines longer than your program. Something’s wrong. http://kirbyfan64.github.io/

How to make a builtin pypy module visible?
by Yicong Huang 28 May '15

28 May '15

Hi, I tried to write a simple test module in pypy: 1. Make a new directory in pypy/modules, and put the code there. 2. Add the new module name in pypyoption.py and built the new libpypy-c.so The reason that I put the module in pypy/modules is I tried to make the module build into libpypy-c.so. :) After that, in pypy console, I am able to import the module and run module's function. However, when I tried to import the module in python script, I met the errors: pypy test.py Traceback (most recent call last): File "<builtin>/app_main.py", line 75, in run_toplevel File "test.py", line 1, in <module> import pypytest ImportError: No module named pypytest Any steps I missed to make the buitin module visible?

Is there similar PyEval_EvalFrameEx() function in PyPy?
by Yicong Huang 26 May '15

26 May '15

We would like to monitor and log all external function calls from a class: when there the function call happen, we capture and log the frame. In python, there is the function PyEval_EvalFrameEx() we might add a callback inside. Is there a similar function in PyPy that would be called when the function call happens?

PyPy OSX buildbot needed
by Matti Picus 24 May '15

24 May '15

this is an explicit call for help. We do not seem to be able to keep a nightly OSX buildbot functioning, even one that builds once a week or so and can be made available for major merges/releases would be better than none. If you have a lead to a modern OSX machine that can donate cycles to PyPy, please respond or join on IRC at #pypy Thanks
