Management of the choice between CPU and GPU

Postby bechialex » Sun Feb 10, 2013 9:31 am

Hi,
I'm using CULA Dense R16a Link Interface with Matlab R2012b on Win 7 64 bit.
My CUDA device is Geforce GT8500.

I have run svd command many times with different matrixes but with the same size and type of data (single).
I have checked the matlab_cula.log and I have noticed that in some cases the computation is executed on the CPU and in other cases on the GPU.

How is managed the choice between the CPU and GPU?

There are configuration options that allow you some degree of control over that decision. Please see the documentation for details.
