Multiprocessing

A multiprocessor computer system where not all of the multiple interconnected central processing units (CPUs) are treated equally.

A multiprocessor computer hardware and software architecture where two or more identical processors are connected to a single, shared main memory, have full access to all input and output devices, and are controlled by a single operating system instance that treats all processors equally, reserving none for special purposes. Most multiprocessor systems today use an SMP architecture.
