mxm_openmp

mxm_openmp, a Fortran90 code which sets up a dense matrix multiplication problem C = A * B, using OpenMP for parallel execution.

The matrices A and B are chosen so that C = (N+1) * I, where N is the order of A and B, and I is the identity matrix.

Usage:

In the BASH shell, the program could be run with 8 threads using the commands: 

        export OMP_NUM_THREADS=8
        ./mxm_openmp
