BRIDGE, INFORMATION PROCESSOR, INFORMATION PROCESSING SYSTEM, AND METHOD OF MANAGING GLOBAL ADDRESS

摘要

To provide resource transparency between nodes on a computer network. In an information processing system composed of a plurality of processor units connected to each other by a switching apparatus, a global address space having a map of the effective addresses of the processor units and shared between the processor units is introduced. A bridge for relaying the input/output bus of each processor unit to the input/output bus of the switching apparatus receives an access request packet having an effective address of a target node from the processor unit, converts the effective address of the target node into a global address by adding to the effective address the target node's node identification number necessary for switching, and outputs the access request packet having the global address to the switching apparatus.
