This will probably be my last post for the project. Id like to thank again my mentor Chis Mueller and backup mentor Stéfan van der Walt, I think they did a lot in helping to make this project happen in the first place.

I've written a bunch of documentation on the CorePy wiki (a lot of it came from the code/README):

http://corepy.org/wiki/index.php?title=CoreFunc

When any updates to this work occur, the wiki page will be updated.

The SciPy talk went pretty well I think, though I wish I had more than 10 minutes to talk. A lot of important things got left out, and I felt there were places I didn't explain things very well. Even so, it was great to be able to go to SciPy and give a talk -- thanks to the people who make SciPy happen! There seemed to be quite a few people interested in CorePy; I had quite a few questions and had some nice discussions with various people.

As promised I used the CoreFunc framework to update Chris' particle simulation demo. Pretty cool stuff -- I was able to move the entire particle position/velocity update calculation into a ufunc. At 200,000 particles I was seeing ~100x speedup over the pure NumPy version, though my measurement wasn't particularly scientific. Check out the glparticle-cf.py file in the project repository/branch (listed in an earlier post).
