Just a few things to clarify: With SGE 5.3, the FIFO is the default scheduling policy. However, you can configure the scheduler to run in SGE EE (Enterprise Edition) mode, which has the 4 additional scheduling policies (deadline, share tree, override, and functional). With SGE 6.0, you get resource reservation and urgency. There are also "projects" and "departments" that you can setup to group the jobs.
All of those are opensource (even the EE mode) and can be downloaded from the SGE homepage: http://gridengine.sunsource.net IMO, Maui is better for backfilling parallel jobs, but SGE is better for the "compute farm" type of workloads. Also, the "array job" functionality parameterizes the job group. To run 200 tasks, all you need to do is a qsub: % qsub -t 1-200 <job script> And inside the jobscript: foo -i file$SGE_TASK_ID.data -p 0.1 And you can monitor all the subtasks as one job. Another advantage is that SGE offers failover functionality, which allows you to have one or more standby masters. -Ron Discover Yahoo! Have fun online with music videos, cool games, IM and more.
