Hi,

I made some changes to the ParallelProgramming wiki page to outline use of the (multi)processing module as well as the threading module.

I'm very much not an expert on this - just researched it for myself, so please feel free to correct/ extend/ delete as appropriate.

I would mention the backport of multiprocessing for python-2.{4,5}: http://code.google.com/p/python-multiprocessing so the amount of editing when one switches from 2.{4,5} to 2.6 is minimal :)

Go for it. The wiki is open to editing. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco

Did you mean this one http://www.netlib.org/scalapack/pblas_qref.html ? As for the ParallelProgramming wiki page, there are some words in section "Use parallel primitives" about numpy.dot still I can't understand from the section: if I get numpy from sources and compile it (via "python setup.py build") in my AMD X2, will numpy.dot use 2nd CPU or not?

Hi,

Their exist open source version of parallel BLAS library. I modified the section "Use parallel primitives" to tell it. But my English is bad, so if someone can check it, it would be nice.

Similarly with the GOTO blas, but I'm not sure if numpy builds with that, so maybe we should take that reference out.

I'd like to let it their, as it is at the same performance level then MKL. ATLAS don't have the same performence level of MKL... If you build GOTO BLAS and build lapack with it, it should link with numpy. But I haven't the time to test this. Fred
