Change CPU/Memory Allocations (Core
Granularity)
Perform this procedure on each compute node to change its CPU and memory resource
allocation at the core level.
Note - To find out if you can perform this procedure, see “Supported Domain
Configurations” on page 174.
The tool makes these changes:
■
Automatically detects Root Domains.
■
Calculates the minimum and maximum resources for all domains, and only enables you to
select valid quantities.
■
Presents viable memory capacities for you to select, based on your core allocations.
■
Modifies domain resources according to the choices you make.
■
(If needed) Stops nonprimary domains.
■
(If needed) Reboots the primary domain with new resources .
■
(If needed) Brings up nonprimary domains with new resources.
The examples in this procedure show a SuperCluster T5-8 compute node. The concepts in this
procedure also apply to other SuperCluster models.
This table shows the allocation plan for this example (see “Plan CPU and Memory
Allocations” on page 175).
