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. A cache coherence controller associated with a first cluster of processors can determine whether speculative probing at a first cluster can be performed to improve overall transaction efficiency. Intervening requests from a second cluster can be handled using information from the speculative probe at the first cluster.
