The majority of multiprocessor systems in the commercial world are based on a single image implementation, that is, one instance of the operating system controlling all the CPUs, the configured memory, and the IO subsystem. As the name “shared memory” implies, all CPUs can access any part of the total physical memory. There are other types of multiprocessor system; multiple nodes each with their own operating system instance, CPUs, memory, and devices that communicate with each other by message passing. These “loosely coupled” systems are not discussed in this taster.
