Scheduler Profiles

You can choose from three scheduler profiles during the installation process: normal, high, and max. You can use these predefined profiles as a starting point for grid engine tuning.

Using these profiles, you can optimize the scheduler for one or more of the following:

• The amount of information about a scheduling run

• The load adjustment during a scheduling run

• Interval scheduling (the default) or immediate scheduling

You can choose from three scheduler profiles:

• normal – This profile uses load adaptation, and interval scheduling, and reports all the information that the scheduler gathers during the dispatch cycle. This profile is the starting point for most grids. Use this profile if your highest priority is gathering and reporting information about a scheduling run.

• high – This profile is more appropriate for a large cluster, where throughput is more important than gathering and reporting all the information from the scheduler. This profile also uses interval scheduling. Use this profile if you want to get better performance at the cost of getting less information about your scheduling runs.

• max – This profile disables all information gathering and reporting, enables immediate scheduling, and disables load adaptation. Immediate scheduling is very useful for sites with high throughput and very short running jobs. The advantage of immediate scheduling decreases as runtime of the jobs increases. This profile can be used in clusters of any size where only throughput is important and everything else is a lower priority.
