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.
