We experienced some account management difficulties today (03/14/2013), mostly caused by exceeding the capacity of our database. We found the cause and fixed all of the issues.
This problem might have affected you in two different ways. First, temporary login problems to the headnodes, and second, failure of some recently allocated jobs on compute nodes. As far as we know, none of the running jobs are affected.
We apologize for any inconvenience this might have caused. If you have experienced any problems, please send us a note (pace-support@oit.gatech.edu).
