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
