Abstract
An information processing method and a system therefor are capable of performing a synchronized operation among CPUs over nodes that cannot monitor each other's internal buses. The system has a plurality of nodes each including one or more CPUs that use monitoring of a common internal bus as a mechanism for synchronizing the CPUs, wherein the plurality of nodes are connected to one another by a connection path that cannot monitor information in a bus in each node. The information processing system includes a transmitter for transmitting information required to perform a synchronized operation in the node or among the nodes through the connection path, and a reflector for reflecting a portion or the overall body of information to the node in accordance with information transmitted by the transmitter so that synchronization of operations of the CPUs over the nodes is realized.
