How to run Cam on cluster

Hi,

I have recently sent email for installation on CAM3.0 on SGI machine but no one have replied me. I changed my mind and now am trying to install the same model on Linux machine. I have run the model on single node using pgf90 and pgcc compiler.
But when I tried to run the model using MPI it is not working. Actually I have no idea how to start using MPI compiler. Following is the specification of my cluster.

This is a linux cluster with 128 processors, and manufactured by ACT (Advanced Clustering Technologies Inc.)

Operating System - Suse 9.3
Other system management software:
Ganglia Monitoring System
TORQUE Resource Manager

The Compilers:
PGI CDK package has been installed on the system.
For 64-bit compilers, set PATH as:
export PATH=/usr/local/pgi/linux86-64/6.0/bin:$PATH
export MANPATH=$MANPATH:/usr/local/pgi/linux86-64/6.0/man

Compiler Language
============
PGF77 Fortran 77
PGF90 Fortran 90
PGHPF High Performance Fortran
PGCC C ANSI and K & R C
PGCC C++ ANSI C++
============

Testing the compilers:

cp /usr/local/pgi/linux86-64/6.0/bench/mpihello/mpihello.f .
pgf77 -o mpihello mpihello.f -lfmpich -lmpich
mpirun -np 4 mpihello
Intel Compilers with MPI:
export PATH=$PATH:/opt/mpich/ch-p4/bin

Compiler Language Command
============ =====================
MPIF77 Fortran 77 mpif77
MPIF90 Fortran 90 mpif90
MPI C Intel C mpicc
MPI C++ Intel C++ mpicxx
============ =====================

Can someone help me to run this model on the machine for more than one node.

Cheers
Siraj
