 Please plenty of time between multiple GPU job submissions.  Like minutes.
-Jobs need to be submitted to the scheduler on host sharptail itself for now and will be dispatched to nodes n33-n37 in queue mwgpu. They can also be submitted from host greentail but remember any output will be in shraptail's /home.
+Jobs need to be submitted to the scheduler via cottontail to queues mwgpu, amber128, exx96.

+This page is old, the gpu resource ''gpu4'' should be used, a more recent page can be found [[cluster:173|K20 Redo Usage]]. Although there might some useful information on this page explaining gpu jobs.
