PARALLEL COMPUTER SYSTEM, AND METHOD FOR ARRANGING PROCESSING LOAD IN PARALLEL COMPUTER SYSTEM

摘要

The present invention addresses the problem of providing a method for arranging the processing load in a parallel computer system, said method being capable of appropriately distributing a processing load that includes the influence of increases/decreases in the communication load between computer processors in conjunction with the migration of processes. The present invention solves this problem by means of a parallel computer system that distributes multiple processing loads with respect to multiple processing nodes, wherein: information regarding the amount of communication between processing loads is obtained; pairs of processing nodes are selected from the multiple processing nodes on the basis of the obtained information, as nodes for which the arrangement is to be changed; a prediction is made regarding the change in the amount of the communication load between these pairs of processing nodes when the processing load is migrated between the selected pairs of processing nodes; and the multiple processing loads are rearranged on the basis of the prediction results.
