Abstract:
1. A parallel computer system comprising a node group having numbers of nodes connected by a network, wherein a job scheduler of a job server which schedules jobs to be executed by a node of said node group comprising: a temperature calculating unit which with a node being used of said node group as an imaginary heat source and with an assumption that a quantity of heat is conducted from a heat source to a surrounding node, calculates a temperature of a surrounding free node based on a distance from the heat source; a free region extracting unit which selects, from a plurality of temperature groups obtained by grouping free nodes on a certain temperature range basis, a temperature group meeting the number of free nodes required by a job according to a temperature and takes out a lowest temperature free node from the selected temperature group as a center node; and a node selecting unit which sequentially selects the necessary number of free nodes starting with a shortest distance free node centered around said center node.
