Hi,
   Can LAM MPI do the following?
 
I want to run MPI jobs across two clusters. On each cluster, only the
head node has a public IP. All compute nodes have private IPs. So a
compute node on one cluster can't send a message directly to a compute
node on the other cluster.
   If LAM MPI was installed on both clusters, (using IMPI) would it
allow MPI jobs to be run across the two clusters? Or would the IPs of
all the compute nodes have to be public for it to work?
 
Thanks.
