FAQ

Two jobs I submitted this afternoon remain "dr" status. I tried to delete them using "qdel -f <jobid>" but it didn't work.

It's because the compute node on which the jobs were running (compute-1-9 in this case) crashed. You can see it's down by going to https://ifp-32.ifp.uiuc.edu/ganglia/. Someone needs to physically go to the lab and reboot the 9th machine from the BOTTOM of the rack. (plug the keyboard and monitor from the back of the rack into the suspect machine first just to check it's really the right machine).
