HP Process Resource Manager (PRM) manual Hier

	automatically created by PRM. PRMID 1 is also reserved. It is known as the OTHERS
	group and is the default for users without user records. You must create this group
	explicitly.) PSET PRM group PRMIDs are assigned by PRM and are not specified
	in the group record.
HIER	Indicates the PRM group is a parent group in a hierarchy and that it has no PRMID.
	The reserved group names OTHERS and PRM_SYS cannot be parent groups. Also,
	you cannot use PRMID 0 for a child group. You can, however, use PRMID 1 for a
	child group.
PSET	Indicates the PRM group is a PSET PRM group. In this case, SHARES is not used.
	Instead, use the CORES and CORE_LIST fields to specify the cores assigned to
	the PSET.

NOTE: When you have PRM groups based on PSETs enabled:

•Do not modify the PSETs manually using the psrset command

•Do not adjust CPU counts in virtual partitions using the vparmodify command

•Do not adjust Instant Capacity (iCAP), Temporary Instant Capacity (TiCAP), or Pay Per Use resources using the icapmodify or ppuconfig commands

•Do not perform online cell operations, using parolrad or any other interface, while PRM is managing the system (For more information, see the WARNINGS section in the prmconfig(1) manpage.)

SHARES	Specifies the FSS PRM group’s CPU shares. Shares are integer values ranging from
	one to MAXINT.
	An FSS PRM group’s resource percentage is determined by its number of shares
	relative to the sum of the shares for its set of sibling groups. If the total number of
	shares is 100, each group’s shares represent the percent of CPU resources that
	the group receives.
	When CPUCAPON mode is enabled, the percentages computed from the SHARES
	values of the FSS PRM groups are also used as caps. For information on this mode,
	see the section “Capping CPU resource use” (page 58). You can enable per-group
	CPU capping using the MAX field discussed next.
MAX	(Available for HP-UX 11i v3 and later.) MAX is an upper bound for CPU consumption
	for the FSS PRM group. It is an integer percent value, ranging from the percentage
	determined by the group’s number of CPU shares to 100.
	The sum of the max values in a configuration does not have to be 100%.
	The percentage computed from the SHARES value, instead of the MAX value, is
	used as the group’s upper bound when CPUCAPON mode is enabled. This mode
	enables capping for all FSS PRM groups in the configuration. For more information
	on this mode, see the prmconfig(1) manpage.
CORES	Is the number of cores assigned to the PSET PRM group. (A core is the actual
	data-processing engine within a processor. A single processor might have multiple
	cores. A core might support multiple execution threads.) The range for this field is
	from 0 to MAX_CORE-1. The number of cores must agree with the number of cores
	in CORE_LIST, if CORE_LIST is specified. If it is not specified, PRM chooses
	which cores to use. However, PRM does not guarantee to choose an optimal set
	of cores.
CORE_LIST	Is the comma-delimited list of core IDs for the cores to be assigned to the PSET PRM
	group. You cannot specify core ID 0 in CORE_LIST. The number of cores specified
	in the CORES field must match the number of cores listed in CORE_LIST.
