In current SMP systems, all of the processors are tightly coupled inside the same box with a bus or switch; on earlier SMP systems, a single CPU took an entire cabinet. Some of the components that are shared are global memory, disks, and I/O devices. Only one copy of an OS runs on all the processors, and the OS must be designed to take advantage of this architecture. Some of the basic advantages involves cost-effective ways to increase throughput. To solve different problems and tasks, SMP applies multiple processors to that one problem, known as [[parallel programming]].

However, there are asome fewreasons limitsthat onimplement theSMP scalabilitymay ofbe SMPcomplex, due to [[cache coherence]] and shared objects.
