Description Stuart Midgley 2016-09-01 07:45:24 MDT

Evening

I have built a nice little cgi script which helps users monitor their jobs.  We have noticed that when an array has a non-1 index, squeue returns a stupid number of array tasks...

and if I look at the output of the command, we have array tasks larger than 22999!

Sigh, thanks.  I guess we really should get upgraded to a more recent version :)
