Kind Code:
A
Abstract:
According to the present invention, methods and apparatus are provided for increasing the efficiency of data access in a multiple processor, multiple cluster system. Mechanisms for improving the accuracy of information available to a cache coherence controller are provided in order to allow the cache coherence controller to reduce the number of transactions in a multiple cluster system. Non-change probes and augmented non-change probe responses are provided to acquire state information in remote clusters without affecting the state of the probed memory line. Augmented probe responses associated with shared and invalidating probes are provided to update state information in a coherence directory during read and read/write probe requests.
