[pymvpa] PyMVPA on PS3 vs. OpenCL & GPU?

it is just that JIT compiler psyco is not available for anything else
than i386 I believe.  pymvpa should work as fine on powerpc architecture
as on any other.

Well -- it depends what you are going to do with PyMVPA -- CUDA might
not provide much of advantage etc.
if in your case it is multitude of searchlights, I guess kernel
computations are not that much of a deal since dimensionality of data is
not high then.  The main issue becomes -- running of multitudes of
optimizations if you rely on iterative methods (such as SVM).  I think
there are SVM implementations for CUDA, but I am not sure what
restrictions they have -- probably would not be able to handle way too
many samples
