with virtual partitions (vPars), Instant Capacity, and Pay per use. For
more information, see the WLM Release Notes
(/opt/wlm/share/doc/Rel_Notes).
WLM allocates cores to a partition based on the CPU limits of the
partition (physical limits for nPartitions; logical limits for virtual
partitions). For example, WLM adjusts the number of cores assigned to a
vPar within the limits of the given vPar’s minimum and maximum
number of cores, which you set using vparmodify.
The way WLM uses group weighting to determine CPU allocations
across partitions is the same as the way it uses group weighting to
determine allocations within a partition. For more information, see
“Weighting a group so it gets more CPU resources (optional)” on
page 178.
