Detailed Description

The default ATLAS batch event loop manager.

It loops over input events according to job configuration. Among the main user-settable properties "FailureMode" controls behaviour of event loop depending on return code of Algorithms.

0: all non-SUCCESSes terminate job.
1: (DEFAULT) RECOVERABLE skips to next event, FAILURE terminates job.
2: RECOVERABLE and FAILURE skip to next events
