In order to address the challenges of N:M semi-structured sparse model computation with various sparse patterns, a flexible configurable sparse matrix multiplication algorithm NM-SpMM is proposed for FT-M7032. NM-SpMM designs an efficient compressed offset addr...
For m≤ n 1.68, the new algorithm is also faster than the best known matrix multiplication algorithm for dense matrices which uses O(n 2.38) algebraic operations. The new algorithm is obtained using a surprisingly straightforward combination of a simple combinatorial idea and existing fast ...

where A is a sparse matrix and C,B are dense matrices. I would like to have some details about the algorithm for sparse-dense matrix multiplication implemented by mkl_sparse_s_mm, i.e., if it uses cache aware strategies, specific micro-kernel implementations to fully leverage CPU registers...
By leveraging the sparsity of the input matrices, our algorithm greatly reduces communication costs compared with general multiplication algorithms [Censor-Hillel et al. (2015) [9]], and thus improves upon the state-of-the-art for matrices with o(n2) non-zero elements. Moreover, our algorithm...
