NOTE: Although the preceding example shows CPU and memory resources allocated equally
within each group, there is no requirement that these resource shares be equal.
If the funding from each department is done equally per department regardless of the number of
users, then an alternate budget model configuration for PRM might result in the following allocations:
• User default group for guests and system administrator: [LINEBREAK]5 CPU shares, 5 memory
shares
• Group A: 50 CPU shares, 50 memory shares
• Group B: 50 CPU shares, 50 memory shares
• Group C: 50 CPU shares, 50 memory shares
Another way of allocating the computing resources equally is to assign each department to an
isolated area using PSET PRM groups. In the following example, each department is allocated its
own core for CPU cycles. Memory is allocated equally using shares.
• User default group for guests and system administrator: 5 CPU shares, 5 memory shares
• Group A: Core 1, 50 memory shares
• Group B: Core 2, 50 memory shares
• Group C: Core 3, 50 memory shares
In the above example, you can also equally allocate memory shares using memory isolation. The
isolated groups will use only their entitlements. They will not loan out or borrow memory from other
groups.
NOTE: Although the preceding example shows each department receiving one core each, there
is no requirement that these PSET PRM groups allocate the same number of cores to each department.
Core 0, however, is reserved for FSS PRM groups within the default PSET.
Application priority model configurations
In an application priority model configuration, you create PRM groups and assign allocations that
reflect the relative importance of the application to your business as well as the resource needs of
the application. You can use tools such as prmanalyze, acctcom, and HP’s GlancePlus to help
you plan your configuration.
For example, suppose you have three departments that use a system. You have analyzed this
system over a period of time and observed the following list in order of descending priority:
• The sales department with five users running:
Order process application◦
◦ Word processing and miscellaneous tasks
◦ Mail application
• The planning department with three users running:
Inventory application◦
◦ Word processing and miscellaneous tasks
◦ Mail application
• The development department with two users running:
CAD design tool◦
◦ Debugging tools
◦ Compilers
