EXAMPLE 4 - MULTIPLE NODES, MULTIPLE CPUs PER PROCESSOR

This is often referred to as the “hybrid mode” MPI approach, where multiple machines are requested and multiple processes are requested. MPI will start a parent process or processes on each node, and those in turn will be able to use more than one processor for threaded calculations.
