Abstract: A data system architecture is described that allows multiple processing and storage resources to be connected to multiple clients so as 1) to distribute the clients' workload efficiently across the available resources; and 2) to enable scaleable expansion, both in terms of the number of clients and in the number of resources. The major features of the architecture are separate, modular, client and resource elements that can be added independently, a high-performance cross-bar data switch interconnecting these various elements, separate serial communication paths for controlling the cross-bar switch settings, separate communication paths for passing control information among the various elements and a resource utilization methodology that enables clients to distribute processing or storage tasks across all available resources, thereby eliminating “hot spots” resulting from uneven utilization of those resources.

Abstract: An information processing system includes a processor responsive to instructions for performing operations. The processor includes instruction queue for fetching and storing instructions in advance of execution and the system is responsive to certain of the instructions for causing execution of a corresponding sequence of instructions. A prefetch monitor includes circuitry for detecting instructions which may result in the execution of a corresponding sequence of instructions. The prefetch monitor further includes an instruction substitution circuit which is responsive to the detecting circuitry for inhibiting the reading of following instructions from a memory to the processor and is responsive to instruction fetching operation of the processor for reading null instructions to the processor.
