Michael,
I am using SunFire X2200, Operating System RHEL 4U4 ES x86_64, Processor AMD Opteron dual core, GNU compilers and LS-Dyna version mpp971_s_7600.2.1224_PGI_linux86-64_lam703
Regards,

-does each cluster node have one or two network interfaces ?
keep in mind that for network connection on both nodes
lam/mpi must have the same opinion over which interface
to connect.
Translated: the hostnames in the lamhost file must resolve
to the same network !
Are the names in your hostfile are generated via the exec host list of
a batch system like PBS / SGE / LSF ?
-2nd trap: in case you do not have a NSF shared working directory
as common working directory for the calculation
the following recipe will help to resolve the real
problem easier:
mkdir -p /scratch/mydynajob on both nodes !
copy all input inclusive lamhosts file to both nodes
then start the job
dyna + lam7.0.3 works perfectly well and easy ...
so probably your problem ist a network / routing problem
of two prcesses not talking over the sanme interface
in case of problems verify also that the 2 CPU / single node job
runs on both nodes, so per se both nodes are configured ok
