Please click the following link to view the slides: PyCUDA and PyOpenCL at Nvidia GTC 2010.
Update: Nvidia has posted a recording of the session. There's also a full list of sessions, with many talks that are worth being watched. In particular, I'd like to recommend the ones by Bryan Catanzaro on Copperhead, which is built on top of PyCUDA, by Tim Warburton on all things GPU-based discontinuous Galerkin. Also check out the poster on Atomic Hedgehog by Cyrus Omar.
