Web1 de jan. de 2015 · The widely used Compressed Sparse Row (CSR) sparse matrix storage format was chosen to carry on this study for sustainability and reusability reasons. We parallelized for Intel Many Integrated Core (MIC) architecture a vectorized SpMV kernel using MPI and OpenMP, both pure and hybrid versions of them. Web1 de dez. de 2024 · For example, “bbmat” and “FEM_3D_thermal” in ELL and “TSOPF_RS_b2383” in both CSR and ELL. Moreover, the SpMV based on CSR and ELL with NEON may cause more cache misses because it needs extra two times of cache access. In further experiments, the SpMV based on CSR and ELL are all accelerated by …
