MAGMA Forum

I have just started exploring magma. I just wanted to know whether a direct implementation of zgemm_ function available with magma (whose signature is same as the one found in blas)?

I did find magmablas_zgemm routine in magma_1.0 which seems invoking cuBlas zgemm function (#define magmablas_zgemm cublasZgemm). If it is true, the performace of magma zgemm will be similar to cublas zgemm?

We just released MAGMA 1.0 but didn't include the ZGEMM. We will add it within a month. We have developed it based on autotuning and it exceeds the CUBLAS's equivalent in performance. See
Jakub Kurzak, Stanimire Tomov, and Jack Dongarra, Autotuning GEMMs for Fermi, UT-CS-11-671 (LAWN #245), Apr 18, 2011.

It is good news that there will be a MAGMA version of zgemm. I look forward to trying it out.
