SMP, as the name suggests, contains a set of a limited number of processors, ranging from 2 to 64, and it shares most of the resources among these processors. An operating system instance operates together with all these connected processors, and these processors commonly share the I/O, memory, and network bus. The essential behavior of SMP is based on the nature of this set of similar connected processors and how they act together on the operating system.
