A two multiple virtual system (MVS) under a single system image (I/O, are shared by all processors) is set forth. Under such a system, it is necessary to partition the main storage into private and shared regions. The hardware mechanism which controls the private/shared storage and performs the necessary broadcasting and cross-interrogate functions increases the performance of a four-way multiprocessor (MP) system and can have from 2.4 x unit processor (UP) to approximately 3.4 x UP performance.
