Guidelines to specifying the number of cores

There are factory-defined resource allocation scalability rules for various activity types that can be adjusted in the user interface HPC Resource Management pane.

The tables in this topic include only activity types that are configurable in the Administration Console via the HPC Resource Management function. The first table describes the purpose of the columns in the tables.

Activity type code The code in the ActivityType table in the AIRReference database
Activity Type This table column lists the activity types that you can select from the list in the Associate HPC Node Group Association pane.
Cores The table column lists the minimum and maximum number of cores that can be assigned to each activity type:
  • 1: The activity type can use only one core. Assigning more cores would not have any effect because the activity type's internal service is limited to using one core.
  • 1 - N or 2 - 2*N (for detailed loss analyses): The activity type can be distributed on an unlimited number of cores, although there may be diminishing returns beyond a certain point. In versions prior to version 11.0, the formula was 1 - N, even for loss analyses.
Activity type code Activity type Description Cores
