This question is a little off-topic for this list, since this list is
for Open MPI-specific questions (and some general MPI questions). You
should really ask this question on the Beowulf mailing list, which
covers any and all topics related to HPC clustering. See
for more information.

Also, you need to be more specifc as to what you really want to do
"integrate" is a vague, overused term. Do you want the scheduler at one
site to be able to manage jobs on the cluster at the other site with no
message-passing traffic between sites? That might be possible.

Or, do you want the two remote clusters to send message-passing traffic
back-and-forth over the internet and behave as a single cluster? That
might be possible, too, but due to the latency and reduced bandwidth of
sending those messages over the internet, the performance would be so
poor as to probably not be worth it.
