More Information
Summary:Aspects include a system, method and computer program product for providing a shared memory translation facility. The method includes receiving a request for access to a memory address from a requestor at a configuration, the receiving at a shared memory translation mechanism. It is determined whether the memory address refers to a shared memory object (SMO), the SMO accessible by a plurality of configurations managed in different zones of memory. Based on determining that the memory address refers to the SMO, it is determined whether the configuration has access to the SMO. Based on determining that the configuration has access to the SMO, the requestor is provided a system absolute address for the SMO and access to the SMO. In this manner direct interchange of data between the configuration and the plurality of configurations is allowed.
