magma_cgesv w/ multiple GPU box

[mh1]

I have successfully download and integrated Magma 1.3. I am currently using magma_cgesv in one part of my application.

I have a machine with multiple GPU's. Will magma_cgesv automatically utilizes both of those GPU's? If not, how do I tell it which one to use (cudaSetDevice)?

Thank You

You need to set the environment variable MAGMA_NUM_GPUS to the number that you want to use. E.g.:

setenv MAGMA_NUM_GPUS 2
./testing_cgesv
