This paper is about multiprocessing within an MVS local network environment. Specifically, it describes a multiprocessing architecture that enables address spaces sunning on any processor of the local network to request and receive service from any other address space running on that processor or on any other processor of the network. In application, a processing hierarchy is proposed wherein the requesting processors are small scale "personal" computers and the service processors are those of large-scale, data base oriented computing systems. The key difference between the architecture presented in this paper and that associated with standard network based systems is that here the application and service appear to reside in the same (requesting) processor. This feature, which gives the small processor the appearance of a large system and provides a basis for migration, is achieved through an extension of MVS herein called the Virtual Service Interface (VSI). VSl integrates the set of otherwise independent MVS operating systems of the local network into a single operating system having a single system image.
