Abstract
A shared-memory system includes processing modules communicating with each other through a network. Each of the processing modules includes a processor, a cache, and a memory unit that is locally accessible by the processor and remotely accessible via the network by all other processors. A home directory records states and locations of data blocks in the memory unit. A prediction facility that contains reference history information of the data blocks predicts a next requester of a number of the data blocks that have been referenced recently. The next requester is informed by the prediction facility of the current owner of the data block. As a result, the next requester can issue a request to the current owner directly without an additional hop through the home directory.
