ABSTRACT:
A data processing system which has a plurality of sets of sub-systems, with each set including: a plurality of processors; a main storage; and a controller for controlling the transfer between at least each of the processors and the main storage. A shared storage apparatus is shared between the sub-systems to store exclusive control information, information on the processor-to-processor communications and an instruction to be transferred between the main storages and the shared storage apparatus when the information is accessed by each sub-system. The instruction designates a main storage address, a transfer data length and specified information on accessing the location of the shared storage apparatus and is decoded by the processors to that the main storage address is transferred to the main storage, whereas the specified information such as a data identifier and a relative address is transferred to the shared storage apparatus.
