Abstract
An apparatus and method is disclosed for allowing a multiprocessor computer system with shared memory distributed among multiple nodes to appear like a single-node environment. The single-node environment is implemented with a memory map that has a unique address for every memory location in the system. Overlapping address spaces in the multinode environment are also assigned unique representative addresses that are translated to actual addresses in conformance with the multinode environment. The apparatus and method allows a wide variety of operating systems to be run on the multinode environment. Additionally, industry standard BIOS and chip sets can be used.
