WebMultiprocessing is divided into the following three types: Symmetric multiprocessing (SMP). In symmetric (or "tightly coupled") multiprocessing, the processors share memory and the I/O bus or data path. A single copy of the OS manages all the processors. SMP, also known as a "shared everything" system, does not usually exceed 16 processors.
