...I was all set to yell at you to read the man page, but it turns out this isn't in there (Good Job Oracle!), and it's not in the Sun Grid Engine admin guide either (Awesome documentation you guys!)

jclass denotes the Job Class to which the job belongs (or blank, as in your example, if the job is not assigned to a job class).

A Job Class is:

A set of jobs that are equivalent in some sense and treated similarly. In Sun Grid Engine, Enterprise Edition a job class is defined by the identical requirements of the corresponding jobs and the characteristics of the queues being suitable for those jobs.

  • Even though I still have no idea what a job class is, like how to use it. But thank you all the same, for at least I know it has nothing to do with me and I can filter this information out with awk. Commented Jan 10, 2014 at 21:33
  • And yes, I have checked the manual and found nothing, so I came here to ask. Thanks Commented Jan 10, 2014 at 21:34
  • @Daniel I know job classes are describe in the SGE docs - I just don't have the relevant books at my fingertips. Poke around and I'm sure you'll find more details :) Commented Jan 10, 2014 at 22:12
