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 M6-32:

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
