It looks like the mpirun that appears in your path first is the mpirun 
from LAM/MPI.  Both MPICH and LAM/MPI provide an "mpirun" (as well as 
mpicc, mpiCC, and mpif77).  For LAM/MPI to operate, you must "lamboot" 
first, starting a small daemon on each node.  You might want to take a 
look at our user manual:

   http://www.lam-mpi.org/using/docs/

As for why you are using LAM/MPI as opposed to MPICH (which is what I'm 
assuming you meant to ask), it's probably because LAM/MPI is installed 
by default on most Red Hat and Mandrake Linux installations.


Hope this helps,

Brian
