Hi all. I ran a 4 hour tutorial on High Performance Python at
EuroPython two weeks back. I've written up a report (49 page PDF, CC
licensed):
http://ianozsvald.com/2011/06/29/high-performance-python-tutorial-v0-...
and I plan to publish a v0.2 updated report in a couple of weeks. It
was a bit of a push writing 49 pages whilst at the conf, I need a bit
of a break to catch up on other stuff now :-)

ShedSkin is covered though I haven't done the profiling yet (I see
Mark's just published some notes on the subject, that's great). If an
even-more-optimal version of the ShedSkin code can be built, I'm all
ears. Currently ShedSkin beats Cython (but possibly just because gcc
4.2 is being used rather than gcc 4.0 - a quirk of my system perhaps).

Armin has tried the pure-python with 'better math' solution (the
fastest src for ShedSkin and Cython) and it brings the trunk version
of PyPy to 4* slower than ShedSkin/Cython (i.e. do no work at all and
it gets within the same order of magnitude as C compiled versions!).
This is pretty impressive.

Someone is also working on a pyOpenCL version to accompany the pyCUDA
examples, that'll go into the v0.2 report. Shout if you have any
improvements, I'd like to make this report a nice tutorial for all
Pythonistas.

Cheers,
Ian.
