Some specific functions are missing in numpy and a pure python
implementation
is too slow. In that case, I implement the specific function in C, as a
python module.

Yes, my toolbox is now nearly completely parallelized with mpi4py.
Some parallelization parts are also implemented in C modules.
It works fine on beowulf clusters, multicores or smps.
