MPE (Multi-Programming Executive) is a discontinued business-oriented mainframe computer real-time operating system developed by Hewlett-Packard for their HP 3000 computers. While the HP 3000s were initially mini-mainframes, the final high-end systems supported 12 CPUs and over 2000 simultaneous users.
It runs on the HP 3000 family of computers, which originally used HP custom 16-bit stack architecture CISC CPUs and were later migrated to PA-RISC where the operating system was called MPE XL.
In 1983, the original version of MPE was written in a language called SPL ( System Programming Language). MPE XL was written primarily in Pascal, with some assembly language and some of the old SPL code.
In 1992, the OS name was changed to MPE/iX to indicate Unix interoperability with the addition of POSIX compatibility. 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.
In 2002 HP released the last version MPE/iX 7.5. [1]
Among others, MPE/iX supports the following list of common commands and programs. [2]
