[slurm-users] Multi-node job failure

[Chris Woelkers - NOAA Federal]

Thanks all for the ideas and possibilities. I will answer all in turn.

Paul: Neither of the switches in use, Ethernet and Infiniband, have any
form of broadcast storm protection enabled.

Chris: I have passed on your question to the scientist that created
the sbatch script. I will also look into other scripts that may make use of
srun to find out if the same thing occurs.

Jan-Albert: The mvapich2 package is provided by Bright and loaded as a
module by the script before mpirun is executed.

Zacarias: The drive that the data and script lives on is used is mounted on
all the nodes at boot.

Thanks,
