Compiling Platform MPI 8 Applications
As with Open MPI, QLogic recommends that you use the included wrapper scripts
that invoke the underlying compiler (see Table 5-4).
To compile your program in C using the default compiler, type:
$ mpicc mpi_app_name.c -o mpi_app_name
Running Platform MPI 8 Applications
Here is an example of a simple mpirun command running with four processes,
over PSM:
$ mpirun -np 4 -hostfile mpihosts -PSM mpi_app_name
To run over IB Verbs, type:
$ mpirun -np 4 -hostfile mpihosts -IBV mpi_app_name
To run over TCP (which could be IPoIB if the hostfile is setup for IPoIB interfaces),
type:
$ mpirun -np 4 -hostfile mpihosts -TCP mpi_app_name
