from pg.15 of that document they're suggesting hundreds of millions of
messages in only a few hours). Is there any kind of buffer or queue that
OpenMPI develops if messages are created too quickly? Does it dispatch them
immediately or does it attempt to apply some kind of traffic flow control?
with this error where a connection is
established, and used for several hours, but after a seemingly random period
of time the program dies stating it can't make a connection?

rrectly.
As a side note, the throughput of this job was around 17 Mbits/sec.
All in all, easily fixed, just a few days of frustration. Thank you all again
for all of your help. It was paramount in enabling me to discover the issue.
Thanks again.

not taking very long so it makes me feel more comfortable about network
communication.
Anyways, please have a look and let me know what
you think could be the issue.

An to edit that, it was compiled to be used with OpenMPI 1.4.1, but as I

Anyhow, let me know if anything seems weird on the OpenMPI communication
subroutines. I don't have any numbers to lean on from experience.
Sorry this e-mail was long. Thank you again for all of your help.

Thanks for all the help! I'm glad to get it finally working and I think with a
little tweaking it should be ready to go very soon.

Hello again,
I believe my administrator has opened the ports I requested. The problem I am
having now is that OpenMPI is not listening to my defined port assignments in
openmpi-mca-params.conf (looks like permission 644 on those files should
enabled.
Any other ideas on what might be causing the hang? Is there a more verbose mode
I can employ to see more deeply into the issue? I have run --debug-daemons and
--mca plm_base_verbose 99.
Thanks!

It looks like the remote daemon is starting - is there a firewall in the way?
