Shirts…

How he came to Python

Search Comparisons

Keynote 2: Jonathon Guyer, Material Scientist

FiPy – Finite Volume PDE Solver

Simulation Images Cahn-Hilliard Phase Field

NumPy/SciPy Talks

NumPy Tutorial Stefan Van Der Walt and David Cournapeau

Reading binary data

Programatic Approach

Declarative Way with NumPy

Generalized Ufuncs

Neighborhood Iterator (for C)

Stats Tutorial: Robert Kern
Monty, meet Carlos.
Generate 10000 noisy datasets from the same parameters.
Use curve_fit() on each dataset and store the fitted parameters.
Look at the mean and covariance of the parameters.

Visualization Talks

Matplotlib
John Hunter
Darren Dale
Andrew Straw
Ryan May
Michael Droettboom

Spines Axes Toolkit 3D Plots

Mayavi Prabhu Ramachandran and Gael Varoquaux

Chaco: Peter Wang

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

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

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

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)…

Eric’s Favorite Talk: Virtual Reality (for a fly…) Andrew Straw Fly
