Hot processor swap in a multiprocessor personal computer system

摘要

A scheme may be used to remove or replace a processor in a multiprocessor computer without the need for turning the computer off to replace the processor. In this scheme, the bus to which the processor is coupled is identified so that all processors coupled to the bus may be placed in sleep mode. This act does not alter the normal operation of processors that may be coupled to another bus. Once the processors are in sleep mode, the processor may be removed or replaced. Afterward, all processors may be returned to normal operation.
