A computing section is provided with a plurality of computing units and correlatively stores entries of configuration information that describes configurations of the plurality of computing units with physical configuration numbers that represent the entries of configuration information and executes a computation in a configuration corresponding to a designated physical configuration number. A status management section designates a physical configuration number corresponding to a status to which the computing section needs to advance the next time for the computing section and outputs the status to which the computing section needs to advance the next time as a logical status number that uniquely identifies the status to which the computing section needs to advance the next time in an object code. A determination section determines whether or not the computing section has stored an entry of configuration information corresponding to the status to which the computing section needs to advance the next time based on the logical status number that is output from the status management section. A rewriting section correlatively stores the entry of the configuration information and a physical configuration number corresponding to the entry of the configuration information in the computing section when the determination section determines that the computing section has not stored the entry of configuration information corresponding to the status to which the computing section needs to advance the next time.
