According to dynamic changes of a system, an autonomic distributed processing system can automatically distribute tasks efficiently, and can reissue the lost task. The mobile agent is suitable in order to realize such a system. In this research, the function of the mobile agent system, AgentSpace, was extended and used. The agents to support processing user tasks efficiently have been implemented. For evaluation of our system, SPMD-type multithreaded program of traveling sales-person problem in case of 13 cities was used, and as a result of executing by four heterogeneous PCs, as compared with the time of executing by one PC, the processing time was shortened to about 35.5% on the average.
