Any simple way to divert calculations in Sage to the graphics card?

Hey,

I'm fairly new to Sage, pls accept my question under this comment:

I've heard that diverting calculations to the graphics card might speed up running time. Person I heard it from uses C and Matlab. How true is it? And if so - is there a simple way to do this in Sage?

I'm looking for any good advice on how to speed up my calculations, I have installed Ubuntu 12.04 for Sage, and stoped any programs from running in the background when I'm running my code. I try to achieve as much power I can get from my computer solely for the purpose of my calculation.

Thanking u on advence!

There are some python modules (pycuda) for doing this, but I haven't seen anyone integrate them with Sage yet. Pycuda is a fairly low-level interface to the graphics card parallel computation API.

On the other hand, you can easily harness multiple cores and threads on a modern CPU in Sage using the @parallel decorator described in the reference manual.
