Memory error when importing optparse module
by Roman Prykhodchenko Nov. 21, 2010

Nov. 21, 2010

Hi guys, I'm trying to port my scripts to pypy but when I import the optparse module I get the error: >>>> import optparse Traceback (most recent call last): File "<console>", line 1, in <module> File "/opt/local/share/pypy-1.3/lib-python/2.5.2/optparse.py", line 84, in <module> from gettext import gettext File "/opt/local/share/pypy-1.3/lib-python/modified-2.5.2/gettext.py", line 49, in <module> import locale, copy, os, re, struct, sys File "/… [View More]

Needs some guidance in writing the kqueue part of select
by Leonardo Santagada Nov. 21, 2010

Nov. 21, 2010

I'm writing the kqueue part of the select module and would like some guidance in how to fix some pieces of it. The code is here: http://paste.pocoo.org/show/293812/ and the specific problems I'm having are: 1) There is no UINTPTR_T in rffi, but INTPTR_T = SSIZE_T so can UINTPTR_T be an alias to SIZE_T? 2) How do I declare that an argument is const in rffi? But if anyone wants to take a look (or maybe more tests http://paste.pocoo.org/show/293811/) please do. I just tested kqueue, but now I … [View More]

Beside its original use as a scripting language for web applications, today Python is a general-purpose language adopted by many scientific applications like CFD, bio molecular simulation, AI, scientific visualization etc. More and more industrial domains are turning towards it as well, such as robotics, semiconductor manufacturing, automotive solutions, telecommunication, computer graphics, and games. In all fields, the use of Python for scientific, high performance parallel, and distributed computing, as well as general scripted automation is increasing. Moreover, Python is well-suited for education in scientific computing. The workshop aims at bringing together researchers and practitioners from industry and academia using Python for all aspects of high performance and scientific computing. The goal is to present Python-based scientific applications and libraries, to discuss general topics regarding the use of Python (such as language design and performance issues), and to share experience using Python in scientific computing education. Topics - ------ * Python-based scientific applications and libraries * High performance computing * Parallel Python-based programming languages * Scientific visualization * Scientific computing education * Python performance and language issues * Problem solving environments with Python * Performance analysis tools for Python application Papers/Submission - ----------------- We invite you to submit a paper of up to 10 pages formatted according to the rules of Procedia Computer Science (http://www.elsevier.com/locate/inca/719435) via the ICCS 2011 conference submission system (http://www.iccs-meeting.org/iccs2011/papers/upload.php) selecting our workshop Python for High Performance and Scientific Computing in the drop-down menu.

Memory consumption of pypy-c translate.py
by Maciej Fijalkowski Nov. 17, 2010

Nov. 17, 2010

Hello. I did a bit of measurments using various techniques and pypy-c-64bit-jit and the outcome is that after a bit of annotation, where memory consumption is 1200M, we get: * 31M of mmaped code blocks for assembler * about 150M I can account for that is jit resume data * about 150M of the rest I can account for. Where is everything else? Can GC trash some memory (like a lot). Here is output of dump.py -r http://codespeak.net/~fijal/jit64.out

Release 1.4
by Armin Rigo Nov. 17, 2010

Nov. 17, 2010

Hi all, We are preparing for the next release of PyPy. A branch was already created http://codespeak.net/svn/pypy/release/1.4.x, twice, but it may get thrown away and re-created again. I have 3 things that I would like to fix before the release: 1. Mac OS/X 64. We have there an issue with asmgcc not finding the gc roots. 2. Try to understand if there is a leak in pypy-c-jit or not. The issue is that it consumes quite a lot of memory and fijal could not, so far, really figure out where it … [View More]

Advice on Compiling Pypy-c for debugging (Stackless support)
by Andrew Francis Nov. 13, 2010

Nov. 13, 2010

Hi: I finally got my hands on a machine big enough to compile pypy-c. I want to try pypy-c with the greenlet package. As I mentioned in previous posts, I want to see how the greenlet package blows up pypy-c and hope that it is a case of simply altering greenlets enough so it will work. I did a test run with -Ojit. It still took about 90 minutes to compile on a Mac with 4G of ram. That said, what would be the right switches to create a version can be placed in a debugger? Where does the C … [View More]

PyPy has a non-profit foundation now
by holger krekel Nov. 10, 2010

Nov. 10, 2010

Hi all, i'd like to point you to your recent joining to the Software Freedom Conservancy (SFC). We decided it's better to bite the bullet and go GPL in exchange for working with a good non-profit foundation and getting some donations. Any objections? Nah, just kidding. But what is true is that the PyPy project joined the Software Freedom Conservancy, see our posts and theirs: http://morepypy.blogspot.com/2010/11/speeding-up-pypy-by-donations.html http://sfconservancy.org/news/… [View More]

Migration to mercurial
by Antonio Cuni Nov. 5, 2010

Nov. 5, 2010

Hi all, as some of you might have noticed by watching the IRC channel, we are finally migrating to mercurial. The actual conversion of the repository will happen at some point during next week (or maybe the week after). One issue that we have to care about is how to convert the author names: in the current svn repository each author is simply indicated by its codespeak username, while with mercurial this is no longer possible as there is no longer a "centralized" server where everyone has an … [View More]
