Hi,

Does anyone have any experience with getting PyMVPA running on a PS3

Here http://qa.debian.org/debcheck.php?dist=testing&package=pymvpa it says:
"Package has a Recommends on python-psyco which cannot be satisfied
on powerpc"
so it might be somehow difficult to get PyMVPA running?
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.
OK! Thanks.
An alternative would be to buy a Direct X11/OpenCL compatible GPU
and work with Python::OpenCL
(http://python-opencl.next-touch.com/index.html). I think that Per
is working with CUDA. Are those results promising? Would it be an
option to support OpenCL in a upcoming major release of PyMVPA
(would be my favourite feature-request :-))?
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
mmh... OK I see. Thanks for clarifying this point.
Not a PyMVPA related question, but do you think one could handle the
limited amount of RAM (PS3) with an external flash-drive working as swap?
Bests,
Matthias
