The intersection of +the processor affinity set and the set of processors owned by the scheduler of +the task must be non-empty. It is not an error if the processor affinity set +contains processors that are not part of the set of processors owned by the +scheduler instance of the task. A task will simply not run under normal +circumstances on these processors since the scheduler ignores them. Some +locking protocols may temporarily use processors that are not included in the +processor affinity set of the task. It is also not an error if the processor +affinity set contains processors that are not part of the system. |
