How much memory have I reserved, and how much am I using?

You can check the memory of your job with the command 'checkjob your_jobnumber'. Then you will get ut something like this:

[torj@stallo-2 ~]$ checkjob 24614

Reservation '24614' (-23:42:32 -> 16:02:17:28 Duration: 17:02:00:00)
PE: 4.00 StartPriority: 384946

MEM: 1000M shows that the job has reserved 1000MB of memory per "task".

[compute-3-3.local:4] means that the job runs on compute-3-3 and is using 4 CPUs. You can then log in to this node (with the command 'ssh -Y c3-3'), and see how much memory this job is using. Use the command 'top', the column RES shows use of memory.
