Obsolescence

Not applicable.

HP-UX Processor Sets

The HP-UX Processor Sets allow a multi-processor system to be partitioned into two or

more groups of processors (CPU's), so that CPU resources for selected applications or

users can be isolated from those of other applications or users. Processor Sets (also

known as psets) may be created and reconfigured dynamically by users who have the

appropriate privileges. Processor Sets was first shipped as part of the optional Software

Pack on HP-UX 11i v1 in October 2001, and is available in the Kernel from HP-UX 11i

v1.6 by default. Where Processor Sets is available in HP-UX, it is supported on all

multi-processor systems. Processor Sets is a full-functioning stand-alone feature, but

psets functionality is also fully supported by and integrated with the optionally available

products HP-UX Workload Manager (WLM) and Process Resource Manager (PRM).

The psrset command creates and manages processor sets.

Summary of Change

•The psrset command has been enhanced to display Locality Domain information.

When used with the option -i, or when used without any option, the psrset will

display, apart from other details, the Locality Domain information for the processor

set.
