Magma_1.3 multi-gpu routines
Hello! I see in the magma_1.3 presentation pdf mentions of multi-gpu dsytrd routines. Where can I find the routines that were used to produce those results? Are they referenced in the testing directory?
Thanks,
Jeremiah

...Or maybe they will appear in a later magma version? I am eager to use this functionality.

Sorry, they weren't quite ready and didn't make the release. They should come out in another release soon.

Thanks for the info.

Hi,
is it present a multi-gpu implementation of SGEMM in Magma 1.3 ?
If not do you think to add it in the future?

No, though a multi-GPU gemm can be easily fashioned out of regular cublas gemm calls on each GPU. It really depends on how the matrices A, B, and C are distributed, e.g., by block-rows or block-columns.
Whereas for the symmetric case, we have a multi-GPU symv and are working on symm, because those cannot be easily composed from cublas symm or gemm calls.
