HP Multi-Programming Executive
MPE (Multi-Programming Executive) is a discontinued business-oriented mainframe computer real-time operating system made by Hewlett-Packard. While initially a mini-mainframe, the final high-end systems supported 12 CPUs and over 2000 simultaneous users.
In 1983, The original version of MPE was written in a language called SPL (System Programming Language). MPE XL was written primarily in HP Pascal, with some assembler 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 1998 HP released the last version MPE/iX 6.0.
