pwir-mpi-matmul

This code implements two sparse-dense matrix multiplication algorithms with reduced communication: 1.5D Blocked Column A and 1.5D Blocked Inner ABC, described in a paper by P. Koanantakool et al. It was a final assignment on a course in Parallel and Distributed Computing. It was written in C++11 with MPI libraries, and tested with openmpi-1.10.2 on my computer and mpich2 on our student server. A detailed report in Polish can be compiled by running make report.pdf.
