MULTIPROCESSOR SYSTEM, AND METHOD OF OPERATING MULTIPROCESSOR SYSTEM

PROBLEM TO BE SOLVED: To provide a multiprocessor system and a method of operating a multiprocessor system that can speed up a boot process even when a plurality of expansion cards of the same type are mounted. SOLUTION: The multiprocessor system includes a plurality of processors, a plurality of input/output hubs (IOHs) connected to the plurality of processors in peer-to-peer fashion and each connected with a plurality of subordinate expansion cards, a routing setting means for setting routing between the plurality of processors and the plurality of IOHs such that each of the plurality of processors can only access a specific IOH selected from the plurality of IOHs, and an initialization means for causing each processor to initialize the plurality of expansion cards after the routing is set by the routing setting means.
