SATHAYE** Abstract The rate monotonic theory and its generalizations have been adopted by national high tech- nology projects such as the Space Station and has recently been supported by major open stand- ards such as the IEEE Futurebus+ and POSIX. 4. In this paper, we focus on the architectural support necessary for scheduling activities using the generalized rate monotonic theory. We briefly review the theory and provide an application example. Finally we describe the architec- tural requirements for the use of the theory.

  • Bi-Directional Optical Backplane Bus for General Purpose Multi-Processor B Oard-To-B Oard Optoelectronic Interconnects
    JOURNAL OF LIGHTWAVE TECHNOLOGY, VOL. 13, NO. 6, JUNE 1995 1031 Bi-Directional Optical Backplane Bus for General Purpose Multi-Processor B oard-to-B oard Optoelectronic Interconnects Srikanth Natarajan, Chunhe Zhao, and Ray. T. Chen Absfract- We report for the first time a bidirectional opti- cal backplane bus for a high performance system containing nine multi-chip module (MCM) boards, operating at 632.8 and 1300 nm. The backplane bus reported here employs arrays of multiplexed polymer-based waveguide holograms in conjunction with a waveguiding plate, within which 16 substrate guided waves for 72 (8 x 9) cascaded fanouts, are generated. Data transfer of 1.2 GbUs at 1.3-pm wavelength is demonstrated for a single bus line with 72 cascaded fanouts. Packaging-related issues such as Waveguiding Plate transceiver size and misalignment are embarked upon to provide n a reliable system with a wide bandwidth coverage. Theoretical U hocessor/Memory Board treatment to minimize intensity fluctuations among the nine modules in both directions is further presented and an optimum I High-speed Optoelectronic Transceiver design rule is provided.

  • BUS and CACHE MEMORY ORGANIZATIONS for MULTIPROCESSORS By
    BUS AND CACHE MEMORY ORGANIZATIONS FOR MULTIPROCESSORS by Donald Charles Winsor A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Electrical Engineering) in The University of Michigan 1989 Doctoral Committee: Associate Professor Trevor N. Mudge, Chairman Professor Daniel E. Atkins Professor John P. Hayes Professor James O. Wilkes ABSTRACT BUS AND CACHE MEMORY ORGANIZATIONS FOR MULTIPROCESSORS by Donald Charles Winsor Chairman: Trevor Mudge The single shared bus multiprocessor has been the most commercially successful multiprocessor system design up to this time, largely because it permits the implementation of efficient hardware mechanisms to enforce cache consistency. Electrical loading problems and restricted bandwidth of the shared bus have been the most limiting factors in these systems. This dissertation presents designs for logical buses constructed from a hierarchy of physical buses that will allow snooping cache protocols to be used without the electrical loading problems that result from attaching all processors to a single bus. A new bus bandwidth model is developed that considers the effects of electrical loading of the bus as a function of the number of processors, allowing optimal bus configurations to be determined. Trace driven simulations show that the performance estimates obtained from this bus model agree closely with the performance that can be expected when running a realistic multiprogramming workload in which each processor runs an independent task. The model is also used with a parallel program workload to investigate its accuracy when the processors do not operate independently. This is found to produce large errors in the mean service time estimate, but still gives reasonably accurate estimates for the bus utilization.

Smith Chairman, Departmental Committee on Graduate Students Design and Implementation of a Multi-purpose Cluster System Network Interface Unit by Boon Seong Ang Submitted to the Department of Electrical Engineering and Computer Science on February 23, 1999, in partial fulfillment of the requirements for the degree of Doctor of Philosophy Abstract Today, the interface between a high speed network and a high performance com- putation node is the least mature hardware technology in scalable general purpose cluster computing. Currently, the one-interface-fits-all philosophy prevails. This ap- proach performs poorly in some cases because of the complexity of modern memory hierarchy and the wide range of communication sizes and patterns. Today's mes- sage passing NIU's are also unable to utilize the best data transfer and coordination mechanisms due to poor integration into the computation node's memory hierarchy. These shortcomings unnecessarily constrain the performance of cluster systems. Our thesis is that a cluster system NIU should support multiple communica- tion interfaces layered on a virtual message queue substrate in order to streamline data movement both within each node as well as between nodes.

  • NIM Standard E Of1.35Inches(=“Singlewidt (Looking Intobin) Bin Connectorfront Methods
    NIM Standard NIM is an acronym for Nuclear Instrumentation Methods. The NIM standard (DOE/ER-0457) was established in 1964 for the nuclear and high energy physics communities. The goal of NIM was to promote the interchangeability of instrumentation modules. Standard NIM modules are 8.75 inches G. Varner – PHYS476 tall and a width which is a multiple of 1.35 inches (= “single width”; “double width” = 2.7 inches) Example: extended pin set Bin connector front (looking into bin) Module Bin CAMAC Standard CAMAC is also an acronym: Computer Automated Measurement and Control. The CAMAC standard (IEEE 583) was established in 1975 and has been used in virtually every physics laboratory and many industrial applications. While other modular instrumentation standards have been widely adopted, the G. Varner – PHYS476 robust CAMAC module and enclosure construction and simple hardware level interface means CAMAC is still a viable choice for instrument applications today.
