purr

The amount of CPU time that has been used by the partition.

perfstat_partitio n_total

entitle ment

The CPU entitlement of the partition.


/proc

cpus

The number of CPUs on which the LPAR can run.


/proc

perfstat_partitio n_total

capped

Determines whether or not the entitlement of the LPAR is

capped

. If yes, then the LPAR cannot exceed its entitlement. If not, then the LPAR will be able to exceed its entitlement if there are spare CPU cycles available from another CPU on the system.

smt

Determines whether or not hyperthreading is available.
