GSOC Ideas
by Lynne Wallace March 28, 2012

March 28, 2012

Hey everyone, I'm a 3rd year student at ed.ac.uk, interested in getting involved in pypy through google summer of code. I've been chatting to Alex Gaynor over irc - his primary suggestion was improving the register allocator. He also suggested browsing through https://bitbucket.org/pypy/extradoc/src/tip/planning/jit.txt to get an idea for projects, but it is a little hard to judge the size and complexity of some of the tasks without a little more internal knowledge. I was wondering if … [View More]

Ask for a point to contribute to pypy
by Iven Hsu March 23, 2012

March 23, 2012

Hi, I'm a student from China, and I've chosen pypy as my thesis subject. I wonder which part should I participate in? My supervisor suggest me to do some performance improvements, so I could list some data and diagrams when I'm doing the thesis defense. And the thesis should have a topic, so all work are around it. I have about half a year time to do a project to impove pypy in some aspects, and write the thesis, although I have to work as an intern in weekdays. I'm familiar with Python and … [View More]

towards more parallelization in the tracer/optimizer
by Timo Paulssen March 23, 2012

March 23, 2012

Hello, I just watched Benjamin Petersons talk on the JIT and one comment that seemed like just a sidethought caught my attention: "we are limited by speed. we don't want to spend three seconds optimizing it as fast as gcc possibly could, because noone wants the program to stop for three seconds." If the raw trace - or a minimally optimized version of it - can be run directly, why not run it once or thrice while waiting for the optimizer to finish optimizing the trace fully? - with … [View More]clever register allocation and whatnot. I guess that, in most cases, the tracer + optimizer will kick in for a loop in "the middle" of many iterations, meaning that after the trace is optimized, it will be run a few more times, maybe hundreds. Now consider this: If the raw or "minimally optimized" trace can be generated very quickly and run maybe a couple of times while the full optimizer runs completely in parallel, then even if the optimizer takes longer than the one pypy currently uses (because of speed limitations), there will still be a win, because a few more iterations have already been finished in parallel. The win will be even more amazing if the tracer kicks in at the very last iteration of a loop, meaning that the program - that would have stopped for the optimization previously - can now return from the function or go do some completely unrelated work, but the next time be very much faster. So the benefits of this are two-fold: One, pypys jit can afford more expensive optimizations and Two, scripts run in pypy will experience less stuttering if there are many different loops hitting the threshold for being considered hot. Another related idea is to see if there are optimizations that can be run in parallel on an incomplete trace, so that when the trace finishes, the optimization is already half-done. Since Pypy still has the GIL (and the STM fork doesn't have a JIT yet), I believe it's beneficial to use a second core for miscellaneous tasks, such as offloading the optimizations. Combined with a more efficient parallel garbage collector, this could lead to smoother speed changes in pypy, as before you'd have first slow -> standstill -> blazing fast. In such a parallelized version you might end up with slow -> unnoticable pause -> faster -> blazing fast. Thank you :) - Timo PS: there's also an incomplete branch that would allow pypy to use weaker optimizations on loops that have not run as often as the current trace limit. The approach here would IMO still be better, because when the trace limit is hit, there is no longer a second pause. [View Less]

pypy on Windows

March 22, 2012

Hello pypy-ers, as a lurker on this mailing list I often read information as in "I do not have a Windows development system" or similiar. I know that Microsoft a) is a PSF member and b) was giving MSDN-Subscriptions to Python Developers and c) also has its own cloud called azure d) has an rather active internal Python community So, was Microsoft allready asked along the lines of "would you be so kind to provide us with a cloudycloud running Visual C compilers, can pypy has cheesburger ?" … [View More]

How to get PIL to install?

Hi, I have been lurking on this list for quite a while. I always feel smarter for having tried to follow the conversations on this list. I'd especially like to thank the people working on getting Cython working. The progress on that project has been fascinating to read about.
