Group IDs

You need to provide a range of IDs that will be assigned dynamically for jobs. The range must be big enough to provide enough numbers for the maximum number of grid engine system jobs running at a single moment on a single host.

A group ID is assigned to each grid engine system job to monitor the resource utilization of the job. Each job will be assigned a unique ID during the time it is running. For example, a range of 20000-20100 allows 100 jobs to run concurrently on a single host. You can change the group ID range for your cluster configuration at any time, but the values in the UNIX group ID range must be unused on your system.
