An information processing system includes a optimal-load arrangement means containing a load analysis means, a load distribution means, and program information. The load-computation execution means contains a hardware processing means and a software computation means. The program information includes resource information and information pertaining to data to be processed and the content of the processing to be performed thereon. The load analysis means has the ability to perform community assignment in which, of the data to be processed, data in regions having heavy loads and communication volumes that can be reduced is assigned to a hardware community and data in other regions is assigned to a software community. The load distribution means divides up the data to be processed such that the data assigned to the hardware community is processed by the hardware processing means and the data assigned to the software community is processed by the software computation means.
