Hi All,
We've got a very large x86_64 cluster with lots of cores on each node,
and hyper-threading enabled. We're running Slurm 18.08.7 with Open MPI
4.x on CentOS 7.6.
We have a job that reports
srun: error: timeout waiting for task launch, started 0 of xxxxxx tasks
srun: Job step 291963.0 aborted before step completely launched.
when we try to run it at large scale. We anticipate that it could take
as long as 15 minutes for the job to launch, based on our experience
with smaller numbers of nodes.
Is there a timeout setting that we're missing that can be changed to
accommodate a lengthy startup time like this?
Andy
