NON-UNIFORM MEMORY ACCESS(NUMA) DATA PROCESSING SYSTEM PROVIDING NOTIFICATION OF REMOTE DEALLOCATION OF SHARED DATA

摘要

PROBLEM TO BE SOLVED: To provide a NUMA architecture having improved queuing, storage and communication functions. SOLUTION: A NUMA computer system 50 has at least two nodes 52 coupled by a node interconnect switch 55. Each of nodes 52 is equal and is coupled between a processing unit 54 coupled to a local interconnect 58 and the node interconnect switch 55. A node controller 56 is functioned as a local agent for the other node 52 by transmitting a selecting instruction received on the local interconnect 58 onto the local interconnect 58 by transmitting the received selecting instruction through the node interconnect switch 55 to the other node 52.
