Title:
COMMUNICATION METHOD, INFORMATION PROCESSOR, AND PROGRAM FOR PARALLEL COMPUTATION
Document Type and Number:
WIPO Patent Application WO/2011/058640
Kind Code:
A1
Abstract:
A plurality of collective communication methods including scattering and gathering as an inter-node communication method used for parallel computation, wherein, in at least one of the methods, information which indicates the arrangement of communication data moving between a first node and a respective plurality of second nodes in a communication buffer is notified to the respective plurality of second nodes by multicasting services from the first node using barrier synchronization or reduction to all nodes, and the respective plurality of second nodes transfer communication data between the first node and the plurality of second nodes using the information indicating the arrangement in the communication buffer.
