Announcing Psyco V2 source release ---------------------------------- This is the long awaited announcement of Psyco V2. Psyco V2 is a continuation of the well-known psyco project, which was called finished and was dis-continued by its author Armin Rigo in 2005, in favor of the PyPy project. This is a new project, using Psyco's code base with permission of Armin. Questions and complaints should go to me (tismer@stackless.com) or the mailing list (psyco-devel@lists.sourceforge.net); Armin is explicitly not in charge of (t)his project any longer! As one of the founders and an active member of the PyPy project, I was very happy to be invited to work on Psyco V2, by FATTOC, LLC. Psyco V2 tries to extend on the original Psyco approach "an extension module that just makes Python faster". Psyco is a just-in-time compiler that accelerates arbitrary Python code by specialization. We believe that Psyco's approach can be carried out much further than it was tried so far, when it's first version was abandoned. This first V2 release is source-only. There is no web-site, yet, and there are no binaries for download. These will be available in a few days on http://www.psyco.org . For the time being, please stick with subversion access, building the extension module from source code. The repository is here: http://codespeak.net/svn/psyco/v2/dist Check-out the repository, and run the setup.py script, given that you have access to a C compiler. Psyco V2 will run on X86 based 32 bit Linux, 32 bit Windows, and Mac OS X. Psyco is not supporting 64 bit, yet. But it is well being considered. The current improvements are, shortly: - Support for Python 2.4, 2.5 and 2.6 - a lot of new builtins - generators, fast and fully supported. More information is coming soon on http://www.psyco.org . This is the beginning of a series of new Psyco versions. Many more improvements are prepared and about to be published, soon, starting with the current version 2.0.0 . Stay tuned, this is just the beginning of psyco's re-birth! For questions about Psyco V2, please join the mailing list psyco-devel@lists.sourceforge.net or contact me on IRC: #psyco on irc.freenode.net . Psyco V2 is fundamentally supported by FATTOC, LLC. See http://www.fattoc.com . Without their continuous support, this work would not have been possible at all. I wish to express my deepest thanks to FATTOC, for allowing me to continue on Psyco with all the energy that this ambitious project needs, and will need. Further special thanks are going to Armin Rigo, John Benediktsson, David Salomon, Miki Tebeka, Raymond Hettinger, Fabrizio Milo, Michael Foord, Dinu Gherman, Stephan Diehl, Laura Creighton and Andrea Tismer, for all the support and discussions. Looking forward to a great future of Psyco! July 17, 2009 -- Christian Tismer :^) <mailto:tismer@stackless.com> tismerysoft GmbH : Have a break!

Hi! I just now saw this announcement. My biggest question is, what would it take to support 64 bit? I just recently switched to Snow Leopard and most of the deployments I manage are on 64 bit now. Regards, Florian Schulze

I looked at this once before because I had a compute-heavy python project on an x86_64 box. I seem to recall a lot of the code made assumptions about the bit-width of C types and needed to have the data structures updated to use things like Py_ssize_t and the like to talk to the python interpreter. A lot of the assembly code should be the same except the stackframe offsets have changed. However, a good implementation would take advantage of the extra registers, which would require some tweaking. I quit pursuing it because it was not something I was motivated to do and I can only imagine the level of frustration I would've developed debugging that sort of code. -Scott -- Scott Dial scott@scottdial.com scodial@cs.indiana.edu
