Language
mpiCC, mpicxx
C++
mpif77 Fortran 77
mpif90 Fortran 90
To compile your program in C, type:
$ mpicc mpi_app_name.c -o mpi_app_name
To check the default configuration for the installation, check the following file:
/usr/mpi///etc/mvapich.conf
Running MVAPICH Applications
By default, the MVAPICH shipped with the InfiniPath software stack runs over
PSM once it is installed.
Here is an example of a simple mpirun command running with four processes:
$ mpirun -np 4 -hostfile mpihosts mpi_app_name
Password-less ssh is used unless the -rsh option is added to the command line
above.

Managing Open MPI, MVAPICH, and QLogic MPI
with the mpi-selector Utility
When multiple MPI implementations have been installed on the cluster, you can
use the mpi-selector to switch between them. The MPIs that can be managed
with the mpi-selector are:
• Open MPI
• MVAPICH
• MVAPICH2
• QLogic MPI
The mpi-selector is an OFED utility that is installed as a part of QLogic OFED
1.4.2. Its basic functions include:
