pypy-stm
by Armin Rigo May 11, 2012

May 11, 2012

Hi all, Here is the very first Python 2.7 interpreter to run existing multithreaded programs on multiple cores. Linux 32 bits. It is horribly slow right now, so consider this as nothing more than a demo :-) http://wyvern.cs.uni-duesseldorf.de/~arigo/pypy-c-r54960-stm.tar.bz2 Documentation: https://bitbucket.org/pypy/pypy/raw/stm-thread/pypy/doc/stm.rst A bientôt, Armin.

I have a standalone version of Reflex now and made a few minor mods to cppyy to use it. That basically reduces the dependencies to Reflex (at runtime) and gccxml (for generation of reflection info, but not needed for the build or runtime). I'll … [View More]

Question about stm_descriptor_init(), tasklets and OS threads
by Andrew Francis May 10, 2012

May 10, 2012

Hi Armin: I am looking at stm_descriptor_init(). Right now makes a call to pthread_self(). In a potential Stackless prototype, I would want it to get the current tasklet instead. Shouldn't this be enough to get a trivial implementation of Stackless (by trivial, one thread. Hopefully by sticking to a single thread we don't have to alter any low level locking stuff) to interact with the transaction module. Enough to analyse programmes? Cheers, Andrew

Mini-sprint next week in Leysin (14-19th of May)
by Armin Rigo May 8, 2012

May 8, 2012

Hi all, With Maciej showing up, we will have "just in time" a mini-sprint next week in Leysin: 14-19th of May. Anyone is welcome to show up, from a day to a week, to talk or work on anything preferrably vaguely PyPy-related. As usual the topics are open, but we were thinking at least to implement some optimization in the JIT: allocating the assembler frames into the heap rather than the stack. (This *is* an optimization because they can survive even after the function returned, which means … [View More]

Biting off more than I can chew
by Greg Bowyer May 7, 2012

May 7, 2012

The other night I got this burning desire to recreate the Azul GPGC (the java pauseless collector) inside pypy, with a view that it could be used alongside the STM work to make pypy a low (no?) pause concurrent VM. When I started tackling the code I realised I might have bitten off a little more than I can chew. My question (probably one of many to irritate and annoy all the fine folks here) would be, is there a sensible way to compile into pypy a small amount of C code that can be used … [View More]
