DATA TRANSFER EXCEPTION HANDLING SYSTEM AND DATA TRANSFER EXCEPTION HANDLING METHOD

摘要

PROBLEM TO BE SOLVED: To reduce unnecessary loads on a network and memory access paths in a distributed memory, multi-node system that decomposes a node-to-node transfer command for each specified amount of data and then performs node-to-node transfers.;SOLUTION: If an exception is detected in an instruction within a data transfer destination node during data transfer between a plurality of nodes, a data transfer exception handling system causes a data transfer source node to report a command-decomposition stop instruction to the data transfer destination node so as to stop a command decomposition in the data transfer source node, thereby suppressing an unnecessary node-to-node transfer to reduce loads on a network.;COPYRIGHT: (C)2013,JPO&INPIT
