### SMPProcessorAffinityMask

This property configures the hex processor mask that indicats which CPU's the worker processes in an application pool should be bound to. The SMPAffinitized property must be set to TRUE for the application pool before this property takes affect.

Note Setting the value of this property to zero means that no SMP affinity is configured. In this case, worker processes can be run on any CPU.
