Configuring CPU and Memory Resources (
osc-setcoremem
)
Minimum and Maximum Resources (Dedicated
Domains)
The tool tracks resource allocation and ensures that the selections you make are valid. This
section describes how the minimum and maximum resources are determined.
This table summarizes the minimum resource requirements for dedicated domains on
SuperCluster T5-8:
Configuration Control Domain
Minimum Resource Requirements
Other Domain
Minimum Resource Requirements
Dedicated Domain with 1 HCA 5 cores / 32GB memory 4 cores / 32GB memory
Dedicated Domain with 2 HCAs 9 cores / 64GB memory 8 cores / 64GB memory
Dedicated Domain with 4 HCAs 17 cores / 128GB memory 16 cores / 128GB memory
The minimum amount of CPU resource that can be assigned to a dedicated domain is
determined by the number of IB and 10GbE devices in the domain (2 cores are required per IB
HCA)
The minimum amount of memory that can be assigned to a dedicated domain is determined as
follows:
■
The number of IB and 10GbE devices in the domain (2 16GB memory granules are required
per IB HCA)
■
The number of cores assigned to the domain (one 16GB granule in the same locality group
is required per 4 additional cores)
The maximum amount of CPU resource that can be assigned to a dedicated domain is
determined by the amount of resources available after taking these points into account:
■
Resources already assigned to other dedicated domains
■
Required minimal resource for dedicated domains with no resource yet assigned
The maximum amount of memory resources that can be assigned to a dedicated domain is
determined by the amount of resources available after taking these points into account:
■
Resources already assigned to other dedicated domains
■
Required minimum resources for dedicated domains with no resource yet assigned
■
The requirement that for each dedicated domain a memory granule footprint is placed in all
locality groups with allocated cores
