<p>PROBLEM TO BE SOLVED: To provide a routing method which enables a CPU at an arbitrary node to access an arbitrary configuration register on a multi-node computer system and can actualize a global register for the computer system. SOLUTION: Provided are an in-node configuration access routing controller 73 which routes a configuration register access request issued at its node by deciding whether the request is address to the node itself or another node and an inter-node configuration access routing controller 120 which connects an in-node configuration access routing controller 73 in each node 10 and routes the configuration register access request addressed to the other node to the destination node 10; and an access request from an arbitrary node 10 is routed to a configuration register at an arbitrary node 10.</p> |
