An outgoing message judging device judges if an outgoing message transmitted by a sending process is cacheable or not; An outgoing message queue queues the outgoing message, when the judging result indicates to be noncacheable. A returning message judging device judges if a returning message transmitted by a receiving process is cacheable or not; A returning message queue queues the returning message, when the judging result indicates to be noncacheable. A message cache unit stores the returning message in association with the outgoing message corresponding to the outgoing message when the judgment result is cacheable, or caches the returning message corresponding to the outgoing message to transmit the returning message to the returning message queue when the judgment result is cacheable.
