1. An interprocess communication facility in a distributed processor system, at least one processor coupled to a storage device, and each processor having storage management services for controlling access to stored data, the interprocess communication facility providing a communication between at least two communicating processes, which are located at one or more processors, the facility supporting a plurality of different data transfer storage management modes, the selection of which is controlled by the processes, the facility at each processor comprising:

  • process interface means coupled to each communicating process for providing a common interface between communicating processes, said process interface means further including means for permitting each communicating process to utilize data transfer storage management modes independently of the data transfer storage management mode chosen by the other communicating process; and

    data access control means communicatively coupled to this process interface means and the storage management services for controlling the storage management services as a function of the data transfer storage management modes chosen by the communicating processes.
