INFORMATION PROCESSING SYSTEM, METHOD, AND INFORMATION PROCESSING APPARATUS

摘要

A system includes a first apparatus coupled to a second apparatus through communication paths. The first apparatus generates leading packets, each including destination information to identify the second apparatus in leading data among data read from a first memory based on a memory transfer request the second apparatus being a destination of the data specified by the memory transfer request, transmits the leading packets to the communication paths, respectively, generates last packets including the destination information in last data among the data read from the first memory based on the memory transfer request, and transmits the last packets to the communication paths, respectively. The second apparatus counts the last packets received through the communication paths, and control to store the last data included in the received last packets in a second memory when the number of the last packets counted coincides with the number of the communication paths.
