Legend:
In Figure 14–3, a generic clusterwide batch queue named SYS$BATCH feeds
jobs to execution queues on each node in the OpenVMS Cluster environment. A
job submitted to SYS$BATCH is placed in the appropriate execution queue to
minimize the ratio of executing jobs to job limits for all execution queues fed by
SYS$BATCH.
For example, suppose execution queues MOE_BATCH, LARRY_BATCH, and
CURLY_BATCH all have a job limit of 5. If MOE_BATCH and LARRY_BATCH
are executing four jobs and CURLY_BATCH is executing one job, the generic
queue SYS$BATCH feeds the next job to CURLY_BATCH.
Refer to OpenVMS Cluster Systems for more information about OpenVMS Cluster
queue configurations. For information about how to create a generic queue, see
Section 14.4.3.
