  • spmm and advanced_spmm dispatched from apply() when nrhs > 2.
  • OMP SpMM: tiled path for 2x2 blocks, otherwise falls back to SpMV.
  • OMP advanced SpMM: tiled path for 2x2 blocks, otherwise falls back to advanced SpMV.
  • Reference and CUDA/HIP/DPC++ stubs falling back to SpMV kernels.
  • OMP test comparing against the reference executor.
