Coupling facility using dynamic address translation

Abstract

A system that employs virtual addressing for structures in a coupling facility. The system operates to share data among two or more processes that execute on central processing complexes. The central processing complexes each have an inter-system channel connected to a coupling facility. The coupling facilitcludes coupling facility receivers where each receiver connects to one of the inter-system channels for making transfers between the coupling facility and the central processing complexes. The coupling facility includes storage, connected to the coupling facility receivers, for storing control objects and data objects at real addresses in one or more structures, where the real address are translatable from corresponding virtual addresses. The coupling facility includes CPUs, connected to the coupling facility receivers and to the storage, for controlling the operation of the coupling facility. Each of the CPUs includes a dynamic address translator for translating the virtual addresses to the real addresses.
