Abstract
A mechanism optimizes the generation of a commit-signal by control logic of the multiprocessor system in response to a memory reference operation issued by a processor to a local node of a multiprocessor system having a hierarchical switch for interconnecting a plurality of nodes. The mechanism generally comprises a structure that indicates whether the memory reference operation affects other processors of other nodes of the multiprocessor system. An ordering point of the local node generates an optimized commit-signal when the structure indicates that the memory reference operation does not affect the other processors.
