Hi,

I'm very new to MPI.
I have 4 Linux pc's. if i want to run the MPI application, what should
i do?

Answers for the my FAQs?

1. How to should i configure & run the mpi applications on that one?
2. All 4 linux pc's should have mpi installation?
3. Whether i should run the mpi application in all 4 pc's separately?

Please give answers if anymore.

Okay, no one else seems to be saying anything, so I'll make a
try at providing brief answers:

In order to be able to run MPI programs, you need to have an
implementation of MPI installed (on all the computers where the
programs will run, as far as I know). I can think of a couple of
ways to find out whether the machines you'll be using have one of
these, but most of these ways are somewhat specific to particular
distributions and MPI implementations. Still, "which mpirun"
might be a starting point.

If you don't have an implementation of MPI installed, the first
step will be to correct that. You might consider Open MPI,
which seems to be emerging as a semi-standard in the UNIX/Linux
world. For more information, a FAQ, documentatio, etc., try
http://www.open-mpi.org .

If you do have an implementation of MPI installed, have a look
at whatever documentation is included.

Hope this helps. I'll try to answer follow-up questions as best
I can.

Thanks a lot Massingill gave me a good starting point.
