Overview

All current tasks in the XEM2 group require submitting many single-core jobs to the farm using either SWIF or AUGER. hcswif is used to submit replay jobs run-by-run to the farm nodes to run in parallel using SWIF (Outlined in the Farm Users Guide). Auger is used to submit multiple single-core jobs that do not need to access the tape library. This includes running multiple mc-single-arm instances, or running rc-externals with multiple cores. The following example(s) are in support of the XEM2 use case.

AUGER
