==History==

The earliest production system with multiple non identical processors was the Burroughs [[B5000]], which was functional around 1961. However at run-time this was [[Asymmetric multiprocessing#Burroughs B5000 and B5500|asymmetric]], with one processor restricted to application programs while the other processor mainly handled the operating system and hardware interrupts. The Burroughs D825 first implemented SMP in 1962.<ref>{{cite web|url=http://ei.cs.vt.edu/~history/Parallel.html|title=The History of the Development of Parallel Computing|author=Gregory V.

IBM offered dual-processor computer systems based on its [[IBM System/360|System/360]] [[IBM System/360 Model 65|Model 65]] and the closely related [[IBM System/360 Model 67|Model 67]]<ref>{{cite book
