multitask_mpi


multitask_mpi, a Fortran90 code which demonstrates how to multitask, that is, to execute several unrelated and distinct tasks simultaneously, using MPI for parallel execution.

In this example, there is a "master" process, identified as process 0, and two worker processes, 1 and 2. Process 0 does nothing but choose the input for the worker processes, transmit it, and wait for the computed results to be returned. The codes executed by process 1 and by process 2 are quite different.

While the typical MPI model has all the worker processes executing the same code, this example shows that that is not necessary.
