Is it Impossible to implement MI using Cg??? I mean performance wise its far far worse than CPU?
I would be Ok to move to Cuda in case its not possible using Cg.

I found an MI implementation using cuda in the internet.

Seems like Cuda based optimisation is possible only for large data sets :(

But i work on small data sets like 64 X 64 X 64.
Plz advice on options to calculate MI using GPU for small data set


Thank you

In general, if the problem is parallel enough, it should be possible to achieve speed-ups using CUDA/GPU over regular CPU. But how much speed-up you get depends on how much data needs to be transferred, how many operations pr data can be done and how interdependent those calculations are.

I don't know enough about MI to say anything more concrete (and I'm not allowed to delete my own posts)...
