Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper
task IDs.
The affinity self command is used to adjust placement decisions when multiple instances of a process
are started. An attract (positive) affinity indicates a preference to have all instances of a process run on
the same node, while a repulse (negative) affinity indicates a preference to have each instance of a
process run on different nodes.
Typically, you would want to monitor how a process on your system best performs, and whether
instances of the same class should be collocated or not.
