MXM_OPENMP, a C++ 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.
In the BASH shell, the program could be run with 8 threads using the commands:
export OMP_NUM_THREADS=8 ./mxm_openmp

MXM_OPENMP is available in a C version and a C++ version and a FORTRAN90 version.
