Why would I need the GPU to do parallel operations? I thought most
modern processors have vector units. I just don't know if there's a
way to have my code use them.
I tried a quick test with pyopengl (as quick as can be done in that

Which version of gcc are you using? Do I remember correctly that you
had the same failure with numpy 1.1.1 when using gcc 3.3 and that the
problem went away when you used gcc 4.1. If you are using 3.3, could
you try with 4.1 and let us know if you run into the same problem?
Thanks,

Dear Robert Kern,
Thanks for your interest in helping me.
Previously I used LinearAlgebra.Heigenvectors. I should have switched to
numpy.linalg.eigh instead of numpy.linalg.eig, since I work with Hermitian
(non-complex and symmetric) matrices.
Kind regards,
Tommy

This means something at some point was not built with gfortran, or that
you did not use gfortran to build numpy.
You are right. I have recompiled everything with gfortran, but now I
get the following error when I try to import numpy: undefined symbol:
_gfortran_concat_string.
I have build a while ago sage-math (where everything is build
locally), but I delete it since it was over 1GB and I am only

Brendan,
Not sure if I understand correctly what you want, but ...
Numpy vector operations are performed in C, so there will be an iteration
over the array elements.
For parallel operations over all pixels, you'd need a package that talks to
your GPU, such as pyGPU.
I've never tried it and if yo
