PROBLEM TO BE SOLVED: To configure a parallel computer system at a computation node which has a subsystem including a memory managed independently of a main memory; and perform direct data transfer without going through the main memory by a communication adapter that relays between the subsystem and another computation node.SOLUTION: An information processing device provided with a CPU and a main memory include: a communication adapter that performs DMA transfer of data to the main memory; a subsystem having a memory independent of the main memory; and a path conversion unit that converts the DMA transfer from the communication adapter to a specific address range of the main memory into DMA transfer to the memory of the subsystem. |
