GPU and CPU both works?

Post by csaba » Wed Feb 27, 2013 7:28 am

Dear all,

I am new to magma. I successfuly installed and compiled testing library.
Playing with ~/magma-1.3.0/testing$ ./testing_dgemm i found only my GPU is doing the hard, dirty work.

I would like to use some CPU cores as well and if I am correct magma does this out-of-the-box.
What I miss?
Do I need some environment variable to set?

Thank you.

Only the higher level (LAPACK) routines use both the CPUs and GPUs. The MAGMA BLAS is mostly for single GPU and some for multiple GPUs. These are used as building blocks in the LAPACK algorithms.
