This PR implements a new "System Batch" scheduler type. Jobs can make use of this new scheduler by setting their type to 'sysbatch'. Like the name implies, sysbatch can be thought of as a hybrid between system and batch jobs - it is for running short lived jobs intended to run on every compatible node in the cluster. As with batch jobs, sysbatch jobs can also be periodic and/or parameterized dispatch jobs. A sysbatch job is considered complete when it has been run on all compatible nodes until reaching a terminal state (success or failed on retries). Feasibility and preemption are governed the same as with system jobs. In this PR, the update stanza is not yet supported. The update stanza is sill limited in functionality for the underlying system scheduler, and is not useful yet for sysbatch jobs. Further work in #4740 will improve support for the update stanza and deployments. Closes #2527 |
