The SciPy Conference 2009 held at Caltech attracted approximately 140 attendees and featured tutorials, keynotes, and various talks on scientific computing topics. Key speakers included Peter Norvig and Jonathon Guyer, covering topics like finite volume PDE solvers and visualization techniques. Additionally, sessions on Cython, HPC, and scientific Python educational initiatives were discussed, along with announcements of upcoming conferences and funding for educational projects.

27. Cython Dag Sverre Seljebotn (Core cython maintainter) Kurt W. Smith: fwrap Google Summer of Code 2009

28. Cython for scientific computation Parallel execution within cython: nogil context manager for conventional thread approach Message passing approach: mpi4py can be used within cython Ongoing work on fwrap (Kurt W. Smith): fortran support using cython as a “glue” Support more recent fortran dialects than f2py (F9x) Generated extension module is Py3k compatible, and does not need fwrap (only need to distribute C sources) Wrappers can be used within cython as well

29. HPC Talks PyCUDA (Nicolas Pinto) CorePy (Andrew Friedley) HPC Panel (Nicolas Pinto, Michael Avaizis, Brian Granger) EC2 Tools (Nicolas Pinto)

30. Overheard Huge IPython Refactor for GUIs Traits in IPython, Matplotlib, SymPy? Draft Documentation for NumPy docstrings nearly complete More questions/comments on parallel programming (but not a lot more answers)…
