<P>PROBLEM TO BE SOLVED: To improve the availability of a whole information system having a plurality of CPU. Ž<P>SOLUTION: Temperature sensors #1 to #n respectively detect the temperatures of CPU #1 to #n. A storage part 11 stores load factor information showing a load factor to be predicted according to the assignment of respective tasks about each CPU. Also, the storage part 11 stores temperature characteristic information showing future temperature to be predicted according to the load factor to be generated according to the assignment of the tasks and the current temperature about each CPU. A load control instruction part 10 predicts the highest temperatures of the CPU #1 to #n in each of a plurality of arrangement patterns showing the ways of assignment of the plurality of tasks to the CPU #1 to #n based on the detected temperature and the information stored in the storage part 11, and assigns the tasks to the CPU #1 to #n according to the arrangement patterns whose highest temperatures are low.
