Parallel Jobs with MPI

Compilation

To compile a program load the module for the desired MPI library (or a toolchain that includes such library). E.g:

module load intel/2016b

for Intel MPI (this is in fact the Intel toolchain, so also includes Intel MKL), or

module load OpenMPI/2.0.2-GCC-5.4.0

for OpenMPI (built with GCC/5.4.0, which is loaded automatically).

Once the module is loaded you can compile your MPI program in the usual way. For exampl, the program mpi_heat2D.c can be compiled with:

mpicc mpi_heat2D.c -o mpi_heat2D_impi
