Title:
NON-UNIFORM MEMORY ACCESS(NUMA) DATA PROCESSING SYSTEM HAVING REMOTE MEMORY CACHE INCORPORATED WITHIN SYSTEM MEMORY
Document Type and Number:
Japanese Patent JP3900479
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an NUMA architecture having improved queuing, storage and communication efficiency.
SOLUTION: A non-uniform memory access(NUMA) computer system and associated method of operation are disclosed. The NUMA computer system includes at least a remote node and a home node coupled to an interconnect. The remote node contains at least one processing unit coupled to a remote system memory, and the home node contains at least a home system memory. In order to reduce access latency for data from other nodes, a portion of the remote system memory is allocated as a remote memory cache containing data corresponding to data resident in the home system memory. In one embodiment, access bandwidth to the remote memory cache is increased by distributing the remote memory cache across multiple system memories in the remote node.
