I'm sorry; I didn't clarify this error.
In a broadcast of only 1 process, it's effectively a no-op. So it doesn't need
to do anything to the buffer
Yes, it does.

Daniel,
Does passwordless ssh work. You need to make sure that it is.

I would also add that scp seems to be creating the file in the /tmp
directory of compute-2-0, and that /var/log secure is showing ssh
connections being accepted. Is there anything in ssh that can limit
connections that I need to look out for? My guess is that it is part of

A very long time (15 mintues or so) I finally received the following in

Hmmm...and that is ALL the output? If so, then it never succeeded in sending a
message back, which leads one to suspect some kind of firewall in the way.
Looking at the ssh line, we are going to attempt to send a message from tnode
2-0 to node 2-1 on the 10.1.255.226 address. Is that going to wo
These nodes have not been locked down yet so that jobs cannot be
launched from the backend, at least on purpose anyway. The added
logging returns the information below:

compute-2-0,compute-2-1 -v -np 10 --leave-session-attached
?? That was all the output? If so, then something is indeed quite wrong as it
didn't even attempt to launch the job.
Try adding -mca plm_base_verbose 5 to the cmd line.
I was assuming you were using ssh as the launcher, but I wonder if you are in
some managed environment? If so, then it could b
This looks to be having issues as well, and I cannot get any number of

Sorry - I forgot that you built from a tarball, and so the debug is "off" by

Unfortunately I didn't see the ssh output. The output I got was pretty much as
before.
You know, the fact that the error message is not prefixed with a host name
makes me think it could be happening on the host where the job is placed by
PBS. If there is something wrong in the user env
I will give this a try, but wouldn't that be an issue as well if the
process was run on the head node or another node? So long as the mpi
job is not started on either of these two nodes, it works fine.
