WLM quick start: the essentials for using WLM
Some common WLM tasks

• whole processors (PSETs)
You can also allocate a fixed amount of CPU resources to virtual
partitions and nPartitions. HP recommends omitting from WLM

needed.
Portions of processors (FSS groups)
One method for providing a fixed amount of CPU resources is to set up
an SLO to give a workload group a portion of each available processor. To
set up this type of SLO:
