Communication device and communication method used in distributed computing environment

摘要

A communication device among a plurality of communication devices is used in a distributed computing system. The distributed computing system executes a target process including a plurality of partial processes by using the plurality of communication devices. The communication device includes a memory and a processor. The memory stores a trail that represents a state of the plurality of partial processes. The processor selects, from among the plurality of partial processes, an uncompleted partial process with a number of equivalent execution results being less than a target number according to the trail. The processor executes the uncompleted partial process selected by the selector. The processor records an execution result obtained by the execution unit in the trail.
