Title:
MULTI-NODE INFORMATION PROCESSING SYSTEM
Document Type and Number:
Japanese Patent JP3169856
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce load on a processor when an identical data is transferred to a shared memory for plural nodes and to perform multicast to an optical node when data is transferred to a shared memory for plural nodes.
SOLUTION: A multicast instruction to be used when data transfer is instructed from a self-node to plural other nodes is provided in an inter-node data transfer instruction which is given as a signal from processors 61 and 6N in a node 1 to a transfer controller in the same node in accordance with the data transfer from the node 1 to a node 2 and plural nodes. Also, multicast control parts 6 and 7 or a multicast control part 8, which hold operation parameters necessary for data and transfer, supervise the ends of multicast instructions and control multicast to plural nodes, are provided in transfer controller 3 and 4 or an inter-node crossbar network 5.
