Intel® oneAPI Math Kernel Library Developer Reference - C
Gets the number of partitions along the leading dimension of the output matrix for parallel ?gemm functions.
int mkl_get_num_stripes(void);
This function returns the number of stripes, that is, partitions along the leading dimension of the output matrix, for parallel ?gemm functions. The number of partitions only applies to ?gemm functions.
The number returned is a hint, and Intel® oneAPI Math Kernel Library may actually use a smaller number.
