Bonjour Ralph,
I wonder : is this plm_rsh_num_concurrent parameter standing ONLY for
rsh use,
or for ssh OR rsh, depending on plm_rsh_agent, please ?
Thanks, Best, G.

That's a big cluster to be starting with rsh! :-)
When you say it won't start, do you mean that it hangs? Or does it fail with
some error message? How many nodes are involved (this is the important number,
not the number of cores)?
Also, what version are you using?

About 9 months ago we had a new installation with a system of 1800 cores and at
the time we found that jobs with more than 1028 cores would not start. At the
time a colleague found that setting
OMPI_MCA_plm_rsh_num_concurrent=256
help with the problem.
We have now increased our processor count to more than 2700 cores and a job
with 2,500 jobs does not start.
Is there any advice?
Best wishes,
Lydia Heck
