How can I prevent my jobs from running on a particular batch node?

Sometimes it is useful to exclude some particular batch node or nodes, most commonly because your jobs are failing on that node and "draining".  Unfortunately you cannot do that directly in SGE.  Instead you have to specify what nodes you do want to use.  Since this is pretty cumbersome we have written a script called qrmnode that does it for you by modifying your .sge_request file.  Please see the Submitting Jobs page for more info on qrmnode.

Also, if you do see a bad node please file a ticket and let us know so we can take it out of service and fix the problem.
