MPE (Multi-Programming Executive) is a discontinued business-orientedmainframe computerreal-timeoperating system developed byHewlett-Packard for theirHP 3000 computers. While the HP 3000s were initially mini-mainframes, the final high-end systems supported 12CPUs and over 2000 simultaneous users.
It runs on the HP 3000 family of computers, which originally used HP custom16-bitstack architectureCISCCPUs and were later migrated toPA-RISC where the operating system was calledMPE XL.[1]
In 1983, the original version of MPE was written in a language called SPL (Systems Programming Language). MPE XL was written primarily inPascal, with someassembly language and some of the old SPL code.[citation needed]
In 1992, the OS name was changed toMPE/iX to indicateUnix interoperability with the addition ofPOSIX compatibility.[2] The discontinuance of the product line was announced in late 2001, with support from HP terminating at the end of 2010. A number of 3rd party companies still support both the hardware and software.[citation needed]
In 2002, HP released the last version MPE/iX 7.5.[3]
Among others, MPE/iX supports the following list of commoncommands and programs.[4]
