Abstract

An information processing system includes a plurality of processors for executing processing according to a predetermined processing request sent from a different device; a switching device for performing data transfer between the individual processors and the different device; and a storage device which is connected to the switching device and enables data transfer to and from the individual processors. At least one of the processors includes a processing request storing unit for storing processing request data sent from the different device to the processor, into the storage device by data transfer. At least another one of the processors includes a processing request reading unit for reading the processing request data stored in the storage device from the storage device by data transfer.
