Thanks for sharing your work with us, having a look at omp.c file, you have mixed MPI with OpenMP, what would you suggest if I'd like to test the performance solely based on OpenMP ?

Hello and thank you for your time in advance! Sorry for the lack of documentation and the late response but I didn't have any time to update and I will do so soon. The omp file was created indeed as a mix between MPI and OpenMP mechanisms with OpenMP being used in the update function since that's what I was tasked to do in the assignment.

If you would like to test solely on OpenMP peformance I would suggest you take a look at the linear.c and the old Mpi files. In the old Mpi code each computer node would perform some calculations and then send its results to a master node. You could try to simulate these mechanisms with OpenMP threads where each thread sends its results to a master thread. This is the basic idea and it can be surely improved I believe.

Thank you for your time
