Affinity level 0. This is the affinity level that is most significant for determining PE behavior. Higher
affinity levels are increasingly less significant in determining PE behavior.
Affinity level 1. See the description of Aff0 for more information.
Affinity level 2. See the description of Aff0 for more information.
Affinity level 3. See the description of Aff0 for more information.
Indicates whether the lowest level of affinity consists of logical PEs that are implemented using a
multithreading type approach. See the description of Aff0 for more information about affinity levels
Indicates a Uniprocessor system, as distinct from PE 0 in a multiprocessor system.
