gMAGNUS: Fast SpGEMM on GPUs for Irregular Matrices via Hierarchical Multisplit
A novel algorithm for sparse matrix-matrix multiplication (SpGEMM) of irregular matrices on GPUs by computing an intra-row reordering of intermediate products, subdividing heavy rows into independent chunks that can be accumulated completely in local memory.
