MPI Compilers
MPI programs are compiled using "wrapper scripts",
which one you use depends on the language being compiled.

Compiling linking and running MPI programs
The MPICH implementation provides those commands
for compiling and linking programs:
$ mpicc -c foo.c
$ mpif77 -c foo.f
$ mpiCC -c foo.cc
and
$ mpicc -o foo foo.o
$ mpif77 -o foo foo.o
$ mpiCC -o foo foo.o
Commands for the linker may include additional libraries.
For example, to use routines from the C math library, use:
$ mpicc -o foo foo.o -lm
Combining compilation and linking in a single command, as shown here:
$ mpicc -o foo foo.c
$ mpif77 -o foo foo.f
$ mpiCC -o foo foo.cc
To run a MPI program, use the "mpirun" command:
$ mpirun -np 4 a.out
To run the program 'a.out' on four processors.
The command "mpirun -help" gives you a
complete list of options.
