Adaptive method for the fine particle size of the large-scale communication and merge communication in a distributed shared memory system

摘要

PURPOSE: A method is provided to adaptively cope with according to an amount of data during setting of communication protocol in each node in a distributed shared memory. CONSTITUTION: A plurality of nodes is connected each other in interconnection network, each node including a processor, a memory and a cache. The distributed shared memory system includes a node controller for controlling a data communication between nodes at each node. The method supports a spectrum granularity scheme in case a type of transmission/reception data shares a coarse-grain. In case the type shares the fine-grain, the method utilizes a cache line transfer scheme to thereby selectively perform a mass transfer and a standard load-store transfer.
