I’m happy to announce the initial public release of boostmpi, an MPI wrapper for Python.

boostmpi is a high-quality Python wrapper around the Message Passing Interface (MPI). MPI is a standardized interface to libraries such as OpenMPI and MPICH that provide high-performance inter-process communication for distributed-memory computing.

boostmpi uses …

I’m happy to announce the initial public release of CodePy, a native-code Metaprogramming toolkit for Python.

The idea is the following:

• You build a string that is actually C code.
• CodePy compiles it, links it, and dynamically loads it into the Python interpreter.

Ta-da: Instant native-code performance, with no …

Nicolas Pinto at MIT was nice enough to invite me over to give a talk in their CUDA class. I made a bunch of slides that I think are of general interest to people who are interested in PyCuda. You can find them here.

Tim Warburton, Jeff Bridge, my advisor Jan Hesthaven and I have recently submitted an article detailing our efforts to accelerate Discontinuous Galerkin computations by using Nvidia CUDA GPUs. DG seems to be a good fit for these machines.

I’ve just rolled release 20080816 of the bindings, with the following stuff changed:

• Fix asserts in gbsv.hpp as suggested by Vardan.
• Sync Thomas’s remaining fixes.
• Apply patch to gels* from Naoki at http://mathema.tician.de/node/391.
• Remove duplication in lapack_names.h.
• Fix line endings in …

I’m happy to announce the availability of PyCuda 0.91. There is full, up-to-date documentation available.

The following exciting stuff is in PyCuda 0.91:

• Support for Windows and MacOS X, in addition to Linux. (Gert Wohlgemuth, Cosmin Stejerean, Znah on the Nvidia forums, and David Gadling)
• Support more …

If you’re anything like me, you go to Brown University and really like Till Tantau’s Beamer LaTeX package for making slides. Unfortunately, Beamer’s theming can be a bit obstinate, and figuring out how to give your slides a Brown flavor (yum!) can be tedious.

Luckily for you …

In this recent paper, Finite Volume guru Randall J. LeVeque addresses an issue that is near and dear to my heart: Computational Scientists must start thinking about the reproducibility of their results.

Scientific results obtained by experimentation are expected to be reproducible. This has long been demanded of published results …
