COMMUNICATION METHOD FOR PARALLEL COMPUTING, INFORMATION PROCESSING APPARATUS AND COMPUTER READABLE RECORDING MEDIUM

摘要

A communication method includes reporting information that indicates disposition of communication data in a communication buffer from a first node to second nodes by a multi-destination delivery using a barrier synchronization or a reduction to all nodes. The communication data is transferred between the first node and the second nodes by at least one of collective communication methods as a node-to-node communication method used in parallel computing. The communication method transfers the communication data by the second nodes using the information that indicates the disposition of the communication data in the communication buffer.
