Definition

A shared-memory multiprocessor is a computer system composed of multiple independent processors that execute different instruction streams. Using Flynns’s classification [ 1], an SMP is a multiple-instruction multiple-data (MIMD) architecture. The processors share a common memory address space and communicate with each other via memory. A typical shared-memory multiprocessor (Fig.  1 ) includes some number of processors with local caches, all interconnected with each other and with common memory via an interconnection (e.g., a bus).
