[mpich-discuss] Help: MPICH for a beginner

[Michele Rosso]

Hi,

I am having my first experience with MPICH.
I am working on a MPI-parallel code that is currently running on a
supercomputer (i.e. Intrepid).
It would be very useful for me to be able to test it (I mean, a reduced
version of it, with a very very course computational grid) on the pc in
my office, but the latter has a single core CPU (32 bit).
If I am not mistaking, it is possible to run a parallel code on a single
core machine, by running many processes simultaneously on the same core.

I need to know how to do that ( i.e.,
how to use MPICH to tell my machine that my code must run on 4 processes
for example, one of which is the master one; how to compile and to run
it etc etc  ).
Is there anyone who may help me? I use Ubuntu 10.04 32 bit and the code
is parallelized with a master-slaves technique.

Thanks in advance,

Michele
