Detailed Description

template<index_t NumDTensor = 0>
struct ck_tile::GemmHostArgs< NumDTensor >

The GEMM kernel host arguments.

Overview
This structure is passed to GemmKernel when creating kernel arguments object. It contain all necessary information required to build proper kernel argument and launch kernel on GPU. This structure defines the GEMM problem configuration by stating all required information like M,N,K sizes and respective strides. NumDTensor describes the number of D tensors.
