Compile the examples as shown here:
Step 4
host1$ cd $HOME/mpi-examples
host1$ mpicc.i -o hello_c hello_c.c
host1$ mpiCC.i -o hello_cxx hello_cxx.cc
host1$ mpif77.i -o hello_f77 hello_f77.f
host1$ mpif90.i -o hello_f90 hello_f90.f90
Note
If the $HOME/mpi-examples directory is not shared across all hosts in the cluster, copy the executables
Step 5
to a directory that is shared across all hosts, such as to a directory on a network file system.
Step 6
Run the MPI program.
The following example shows how to run an MVAPICH MPI C program Hello World:
host1$ mpirun_rsh -np 2 -hostfile /tmp/hostfile $HOME/mpi-examples/hello_c
Hello, world, I am 0 of 2
Hello, world, I am 1 of 2
