Released: PyPy 1.2, JIT included
by Armin Rigo March 12, 2010

March 12, 2010

================================== PyPy 1.2: Just-in-Time Compilation ================================== Welcome to the PyPy 1.2 release. The highlight of this release is to be the first that ships with a Just-in-Time compiler that is known to be faster than CPython (and unladen swallow) on some real-world applications (or the best benchmarks we could get for them). The main theme for the 1.2 release is speed. Main site: http://pypy.org/ The JIT is stable and we don't observe crashes. … [View More]Nevertheless we would recommend you to treat it as beta software and as a way to try out the JIT to see how it works for you. Highlights of This Release ========================== * The JIT compiler. * Various interpreter optimizations that improve performance as well as help save memory. * Introducing a new PyPy website at http://pypy.org/ , made by tav and improved by the PyPy team. * Introducing http://speed.pypy.org/ , a new service that monitors our performance nightly, made by Miquel Torres. * There will be ubuntu packages on "PyPy's PPA" made by Bartosz Skowron; however various troubles prevented us from having them as of now. Known JIT problems (or why you should consider this beta software): * The only supported platform is 32bit x86 for now, we're looking for help with other platforms. * It is still memory-hungry. There is no limit on the amount of RAM that the assembler can consume; it is thus possible (although unlikely) that the assembler ends up using unreasonable amounts of memory. If you want to try PyPy, go to the "download page" on our excellent new site at http://pypy.org/download.html and find the binary for your platform. If the binary does not work (e.g. on Linux, because of different versions of external .so dependencies), or if your platform is not supported, you can try building from the source. What is PyPy? ============= Technically, PyPy is both a Python interpreter implementation and an advanced compiler, or more precisely a framework for implementing dynamic languages and generating virtual machines for them. The focus of this release is the introduction of a new transformation, the JIT Compiler Generator, and its application to the Python interpreter. Socially, PyPy is a collaborative effort of many individuals working together in a distributed and sprint-driven way since 2003. PyPy would not have gotten as far as it has without the coding, feedback and general support from numerous people. The PyPy release team, Armin Rigo, Maciej Fijalkowski and Amaury Forgeot d'Arc Together with Antonio Cuni, Carl Friedrich Bolz, Holger Krekel and Samuele Pedroni and many others: http://codespeak.net/pypy/dist/pypy/doc/contributor.html [View Less]

speed.pypy.org update
by Armin Rigo March 8, 2010

March 8, 2010

Hi all, Fijal may comment on this more, but note that he tweaked the number of runs of the benchmarks displayed by speed.pypy.org, which explains the jumps we see in some of them. The positive-for-us jumps, I should add :-) I think that we should remove the history up to today, as it makes little sense to compare... A bientot, Armin.

Getting anywhere?
by Armin Rigo March 5, 2010

March 5, 2010

Hi Maciek, It's now been two days since you last checked in some text in svn/user/fijal/website/. Can you please confirm that you are still working on it? I have nothing against general hacking, but just to make it clear, I plan to not merge most of what we do now inside 'release/1.2.x', so that's not release work. A bientot, Armin.

next Leysin sprint?
by Armin Rigo March 4, 2010

March 4, 2010

Hi all, This is a quick poll to know if there would be people interested in attending the next sprint in Switzerland, one week after Easter, roughly 10-17th April 2010. I guess the conditions for it to happen are that I am not the only "core developer" (cfbolz?), and there are at least a couple of extra people with whom to sprint. The sprint topics are completely open. The basic idea is to do the sprint in Leysin, but I am also open to the idea of making a 2nd sprint in Bern with a topic … [View More]

cobra server at the Uni Düsseldorf
by Carl Friedrich Bolz March 3, 2010

March 3, 2010

Hi all, we need to do some server restructuring at the university and in the process need to use Cobra for other things (we will get some other machine back after the reshuffling). Sorry about the disturbance. Could people please check their home directories for things that need to be kept and move them elsewhere? We plan to shut Cobra down on the 19th of February, if somebody cannot make it till then, please send me a mail. Cheers, Carl Friedrich

Release and tags
by Maciej Fijalkowski March 2, 2010

March 2, 2010

Hello. Can we copy trunk -> dist for the release, so we don't block any new development because of the release? There was the point of dist, even if we forgot it completely. Cheers, fijal

gsoc for pypy...
by René Dudfield March 2, 2010

March 2, 2010

hi, gsoc is on again... for your information the python mailing list for it is here: http://mail.python.org/mailman/listinfo/soc2010-mentors It would be good to have a wiki page(or blog post? ... err a text file available via http) of project ideas for pypy... if there are any pypy people mentoring that is. With the pygame project last year, we found having a project page for suggestions of acceptable projects helped students pick things they were interested in, and things the project … [View More]
