"Official Support" phooey. "Windows execution hosts" even more phooey. However "Accounting" Oh yes please! I lost hair and sleep over that confounded "accounting" file. Eventually restored sanity with a perl script that put the entries in order by month and weeded out the half that were dead jobs with no resource usage attached ... > The users at gridengine.sunsource.net mailing > is extremely high traffic, so you usually get > pretty good support for questions.

Our cluster is simple enough (66 identical nodes) that we can re-build that from scratch. More difficult is any adjustment to the calling scripts, the batchblast script that cuts a concatenated fasta file into single sequences, and issues the qsub -t command And then there's grocking the underlying paradigm; in sge5.3 the queue is something that describes a computing resource in sge6 (I believe) a queue characterises a job. So in 6 you submit a job to a queue ("urgent", "batch", etc) whereupon it takes on that queue's characteristics. In 5 it was the job of the scheduling system to decide which computing resource (also called a queue) should process a given job based solely on the flags in the qsub command.

Unless you pay nothing, then you get more.
