Parameters

• slot slot-number: Specifies an IRF member device by its ID.

attract strength: Sets a positive affinity in the range of 1 to 100000. The higher the value, the stronger the preference for the process to run in the specified CPU.

default: Sets the affinity to the default, a positive affinity of 200.

none: Sets the affinity to 0, which means the active process has no preference for any location and the system determines its location.

repulse strength: Sets a negative affinity in the range of 1 to 100000. The higher the value, the weaker the preference for the process to run in the specified CPU.
