Hello Jigar
-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

am using precompiled LSDyna binaries with LAM 7.0.3. When I
run the job using just one node, it runs fine. But if i run
the job over the network on 2 machines, it fails giving an
error
