Hi, I apologise if I’ve failed to find this in the documentation (and am happy 
to be told to RTFM) but a recent issue for one of my users resulted in a 
question I couldn’t answer.

LSF has a feature called a Pre-Exec where a script executes to check whether a 
node is ready to run a task.  So, you can run arbitrary checks and go back to 
the queue if they fail.

For example, if I have some automounted filesystems, and I want to be able to 
check for failure of the automounted, in an LSF world, I can do:

  bsub -E “test -f /nfs/someplace/file_I_know_exists” my_job.sh

What’s the equivalent in SLURM?

Thanks,

Tim
