PARALLEL COMPUTER, COMMUNICATION CONTROL DEVICE AND METHOD OF CONTROLLING COMMUNICATION

摘要

A parallel computing device includes a plurality of communicatively interconnected nodes for executing an arithmetic process. Each of the plurality of nodes includes: a measurement unit configured to measure a communication bandwidth up to a destination node based on a communication scheme among the nodes, and a control unit configured to control a size of a packet transmitted to the destination node according to the communication bandwidth measured by the measurement unit.
