Parallel Charmm and RedHat 7.1

[David Chalmers]

Hi All,

I am trying to run the parallel version of Charmm (27b4) on our
Linux/Intel cluster.  I have managed to get Charmm compiled using both f2c
g77 (the lite version) with lam-6.3.1.  I can get Charmm to run using
mpirun on a single processor but it dies (or is killed) with two.
Can anybody help me with a pointer to where I am going wrong?

David


Here is some input and output:
