ABSTRACT OF THE DISCLOSURE A multiple processor system in which a plurality of co-equal processors share a common memory which includes a data structure for storing machine state information for a plurality of processing tasks (jobs). The instruction set of each of the processor includes a job processor instruction for storing in the data structure the current of the machine state information of a processing task being executed by a processor at the time such execution has been stopped either because of an interruption thereof or because an allotted time period assigned to a processor for executing that task is over. The processor can then select another processing task and issue another instruction (JP LOAD) to obtain the machine state information therefor from the data structure to permit such other task to be executed using such machine state information. A further instruction for permitting a faster load operation can also be issued by a processor when only a portion of the machine state information is required to be loaded. Other instructions are provided for various purposes useful in the multiple processor context.
