Sharing Resources within a Host

If you run multiple packages per host, or wish to share the resources of a host between a package

and other nonpackage workloads, you must specify which specific processes are to be considered

part of that workload. You must also select how to create the resource boundaries between the

workloads. There are three mechanisms that you can use to specify the members of the workload:

• By the username of the process

• By the application path used to start the process

• By using the gwlmplace command to explicitly identify a particular process as a member of the

workload. This can be added to the package startup script.

There are also three options for creating resource boundaries between the workloads:

• HP Integrity Virtual Machines

• Fair Share Scheduler groups

• Processor Sets

Which partitioning mechanism you choose to use within a given host depends upon availability;

however, virtual machines and Fair Share Scheduler groups are typically preferable to processor sets

because they support sub-CPU resource allocation. This frees up additional resources that can be

shared whenever the package is not active on a given system.
