If you're unsure of your number they can be found here . Queues are limited to the number of cpus requested in your application. No queue is allowed more than 120 cpus or 60Gb of memory.
Queues also have a minimum limit on the number of cpus.
This is set to 8 for those who have only requested 16 cpus and 16 for all other primary queues. PBS gives short jobs higher priority so jobs in this queue should run before other, longer, queued jobs. Job submission is either from the command line using the qsub command or through the graphical interface to this, xpbs . The option -k oe simply tells PBS to send job output and errors to the files jobscript.o jobnumber and jobscript.e jobnumber . Memory can be specified as in Kilobytes, Megabytes or Gigabytes with the suffices kb, mb or gb.
