group, use the procedure is described in HP Process Resource Manager User's Guide, “Assigning
secure compartments to PRM groups.”
6.1.3.1 Input Data
SRP prompts for the following data. You can also specify a variable name and value in the command
line, as described in
13.1 Creating an SRP Compartment or Adding Data to a Compartment.
PRM Group
Name
Name for the PRM group.
Variable Name: prm_group_name.
Default: The SRP compartment name.
PRM Group
Type (FSS
or PSET)
Specifies the type of PRM group. A Fair Share Scheduler (FSS) PRM group uses a
CPU entitlement mechanism that is specified in shares. An FSS group uses the Fair
Share Scheduler (FSS) in the HP-UX kernel within the system’s default processor set.
A Processor Set (PSET) PRM group uses a CPU entitlement mechanism that is
specified by assigning a subset of the system’s cores to the PRM group. (A core is the
actual data-processing engine within a processor. A single processor might have
multiple cores. Processes in a PSET have equal access to CPU cycles on their
assigned cores through the HP-UX standard scheduler.
Variable Name: prm_group_type.
Default: FSS.
PRM FSS
group CPU
shares
(Valid for FSS groups only) The number of CPU shares allocated for this group. PRM
determines the actual amount of CPU allocated for this group by calculating the
number of shares allocated for this group divided by the total CPU shares allocated.
Variable Name: prm_cpu_shares.
Default: 10.
PRM FSS
group CPU
cap
(Valid for FSS groups only) The maximum percentage of CPU available for this
group.
Variable Name: prm_cpu_max.
Default: No cap.
PRM FSS
group cores
(Valid for PSET groups only) The number of core processors allocated for this group.
Variable Name: prm_cores.
Default: 1.
PRM group
memory
shares
The number of memory shares to allocate to this compartment from the available
system's memory for user processes. PRM determines the actual amount of memory
allocated for this group by calculating the number of shares allocated for this group
divided by the total memory shares allocated.
Variable Name: prm_mem_shares.
Default: 10.
PRM group
memory cap
Specifies a max (upper bound) for memory consumption of system’s memory for user
processes. The value is expressed as a percent, which is an integer value, ranging
from the percentage determined by the group's number of memory shares to 100.
Variable Name: prm_mem_max
Default: No cap
PRM group
The amount of physical memory allocated to this group for shared memory. This
