Dear all, I'm trying to find a brief explanation about the parallel (MPI) implementation of matrix-vector multiplication and matrix-matrix multiplication in PETSc. I have used them for some experiments for a research paper and I need to provide a brief explanation about the implementation of them. Is there a paper that I can read about that? If not, can anyone please help me find the source code that includes the implementation of those two functions?
Thanks a lot, Majid.
