Hi,

Several high-level resources about cuBLAS mention the support of INT8 matrix multiplication (in this cuBLAS introduction, this blog post or this one).

However, after looking at the online documentation and doing some actual experiments on a Titan X Pascal, it is unclear to me whether cublasGemm supports INT8 as the computation precision or not.

The closest I can find is the cublasGemmEx function that supports INT8 data as inputs but does the computation with half float at minimum.

Is the documentation not up-to-date or am I missing something?

Thanks,

Guillaume
