[CSC 435] Watch those job submissions

[Andrew J. Pounds]

I had to kill a few jobs this everning because they were hung or were 
running on henry.  Remember -- don't run on henry -- just submit jobs 
from there.  As far as hung jobs there is a safety net built in to 
PBS/Torque for this -- the amount of runtime.

In your PBS script you can set the maximum amount of walltime.

#PBS -l nodes=1:lab218:ppn=10
#PBS -l walltime=2:00:00

of

#PBS -l nodes=1:lab218:ppn=10,walltime=2:00:00

Will set the amount of time your job is allowed to run to 2 hours.  On 
these problems I can't imagine your benchmarking times taking more than, 
say, 6 hours per test -- but some of you have set your times to multiple 
days.  Protect yourself and keep those times short so if you do have a 
problem you are not waiting for multiple days to discover the problem.

To give context, I ran 200 benchmarking OpenBLAS jobs in under 10 minutes.
