Dear Magma developers,

I was looking at the documentation for the zgemm_vbatched here.
From the documentation it was not clear if the pointers
m, n, k, lda, ldb, ldc, dA_array, dB_array, dC_array
should be pointing to device or to host memory.

Could you please clarify.

Thank you in advance!

Best regards,

Nils

Hi Nils, 

All arrays holding pointers, sizes, and leading dimensions should reside in the GPU memory.
