Notice that the identification and distinction between PC-based clusters/servers, minicomputers, mainframes, and supercomputers aren't based on size, performance, or price, but system architecture, extensibility, and reliability; As integrated circuit technology evolves, a mainframe could be the size of a minicomputer (e.g. IBM System 390 Integrated Server 3006), a minicomputer could be a size of a relatively big personal computer/PC based server (e.g. IBM i5 515), while a regular laptop PC could achieve the performance of multi-million dollar mainframe in 1980s just by emulating it.

|Least concerned; programs are usually specifically built for specific supercomputer; sometimes supercomputers are even built for a specific task (e.g. Anton series)
