<p>PROBLEM TO BE SOLVED: To easily judge which of a node characteristic memory space and a memory space for inter-node communication is accessed and to easily and speedily judge in which of the node characteristic memory space and memory space for inter-node communication a fault has occurred in the access to a memory. SOLUTION: In a memory controller 116-1, when it is confirmed that a communication space access flag is set to a transaction issued by a communication driver 115-1 in access to the memory 113-1, it is judged that the memory space for inter-node communication is accessed and the transaction is held; and when a fault has occurred in access to the memory 113-1 and when it is confirmed that the communication space access flag is set to the held transaction, it is judged that a fault has occurred to the memory space for inter-node communication.</p> |
