HP-UX System Administrator's Guide: Overview HP-UX 11i v3 (B3921-90011, September 2010)

NOTE: WLM manages workloads on individual servers. To manage workloads on multiple servers,
install and configure WLM on each of the servers.
WLM can be integrated with HP Serviceguard by storing the WLM configuration file in a file
system shared by all nodes in the cluster and then activating the configuration on each node
independently.
Alternatively, you can use the HP Integrity Essentials Global Workload Manager (gWLM) to
manage workloads across multiple servers. gWLM allows you to define resource-sharing policies
that can be used across the servers.
How to Obtain
The Workload Manager is available as a standalone product that can be purchased from an HP
authorized reseller or is available in the following operating environments:
• DC-OE - Data Center Operating Environment
• VS-OE - Virtual Server Operating Environment
• MC-OE - Mission Critical Operating Environment
For Further Information
Detailed information about the Workload Manager is available on HP’s web site at:

Processor Sets (PSETS)
Processor Sets, a key technology underlying the Process Resource Manager and the Workload
Manager, can also be used on its own.
Technology Summary
A processor set represents a set of cores grouped together as an independent scheduling domain
for use by the HP-UX scheduler for exclusive access to applications assigned to that processor
set. Processor Sets allow you to isolate compute intensive or high priority applications from other
processes running on a server giving you greater control over the scheduling of critical processes.
Processor Sets may be created and re-configured dynamically by users who have the appropriate
privileges.
The Processor Sets technology can be used alone, but is often used in conjunction with the Process
Resource Manager (PRM).
Tools to Administer/Configure
The psrset command creates and manages processor sets.
How to Obtain
The PSET technology is included in HP-UX 11i version 3.
