Hyper-Threading state of cores assigned to a specific PSET group; you can also modify the
Hyper-Threading state of the system. (Modifications to the Hyper-Threading state should
not be made while WLM is running.) For more information, see wlmconf(4) or the HP-UX
Workload Manager User’s Guide.
• When referring to hardware, CPUs are now referred to as cores in the documentation and
in WLM displays or data reports. A core is the actual data-processing engine within a
processor. A processor might have multiple cores, and a core might support multiple
execution threads through Hyper-Threading. The term “CPU” is still used when referring
to concepts such as “CPU resources” or “CPU utilization”; whenever the number of
physical processing devices is reported by WLM or discussed by the documentation, the
number will be stated explicitly in terms of cores. Note also that PSET sizes and Instant
Capacity (iCAP) partitions are now expressed in terms of cores.
NOTE With Hyper-Threading disabled, each core is seen as a CPU. With
Hyper-Threading enabled, each core can be seen as multiple, logical CPUs.
•The wlminfo par and wlminfo host commands now explicitly display core statistics,
such as in the following display for the wlminfo par command:
Hostname Intended Cores Cores Cores Used Interval
• The wlminfo group command now displays memory utilization of all groups in the
current deployed configuration. In addition, this command now supports the -v option to
display each group’s gmincpu, gmaxcpu, gminmem, and gmaxmem values, if they are
available in the current deployed configuration. This new option is ignored if live data is
not being displayed (for example, when the -o option is being used). If memory
management is not being used, a dash (-) instead of a zero is displayed in the ‘Mem
Shares’ column. If a group’s gmincpu, gmaxcpu, gminmem, or gmaxmem value is not
assigned in the current configuration, a dash (-) is displayed in the corresponding column.
For more information, see wlminfo(1M) or the HP-UX Workload Manager User’s Guide.
• WLM supports the use of Extended Regular Expressions (EREs) for defining alternate
names for application records. This support requires that PRM C.03.02 or later is running
on the same system. For more information, see wlmconf(4) or the HP-UX Workload
Manager User’s Guide.
• WLM supports placement of processes and assignment of user access based on Unix
groups. You can assign Unix groups to workload groups by defining the uxgrp record in
the prm structure. Processes whose effective group ID (GID) matches a Unix group record
