  • High-performance data-parallel input/output

    Creator:
    Moore, Jason Andrew
    Abstract:
    Existing parallel file systems are proving inadequate in two important arenas: programmability and performance. Both of these inadequacies can largely be traced to the fact that nearly all parallel file systems evolved from Unix and rely on a Unix-oriented, single-stream, block-at-a-time approach to file I/O. This one-size-fits-all approach to parallel...

  • An experimental investigation of scheduling non-identical parallel processors with sequence-dependent set-up times and due dates

    Creator:
    Smith, Terrence A.
    Abstract:
    An experimental investigation of factors effecting scheduling a system of parallel, non-identical processors using a series of experimental designs was carried out. System variables included were processor capacities relationships, sequencing and assignment rules, job size, and product demand distributions. The effect of the variables was measured by comparing mean flow...

  • Resource placement, data rearrangement, and Hamiltonian cycles in torus networks

    Creator:
    Bae, Myung Mun
    Abstract:
    Many parallel machines, both commercial and experimental, have been/are being designed with toroidal interconnection networks. For a given number of nodes, the torus has a relatively larger diameter, but better cost/performance tradeoffs, such as higher channel bandwidth, and lower node degree, when compared to the hypercube. Thus, the torus is...

  • A block method approach to solving the Laplace equation on a parallel computer

    Creator:
    Hitchcock, Paula Ann
    Abstract:
    This paper continues exploration in the area of programming for parallel computers. The appendix to the paper contains an extensive survey of the literature related to parallel computers and parallel programming techniques. The paper itself presents a new approach to solving the Laplace equation on a. parallel computer. A new...

  • A study of liquor side fouling in sulfite spent liquor evaporators

    Creator:
    Yoon, Woon-young
    Abstract:
    The effects of possible operating variables such as flow rate, surface temperature, bulk temperature, solids contents, sulfate addition and pH on the fouling of sulfite spent evaporators were studied. The study pointed out that the Ca⁺⁺ concentration difference between heated surface and bulk is the most important factor for fouling...

  • On resource placements and fault-tolerant broadcasting in toroidal networks

    Creator:
    AlMohammad, Bader Fahed AlBedaiwi
    Abstract:
    Parallel computers are classified into: Multiprocessors, and multicomputers. A multiprocessor system usually has a shared memory through which its processors can communicate. On the other hand, the processors of a multicomputer system communicate by message passing through an interconnection network. A widely used class of interconnection networks is the toroidal...

  • Specification of parallel processing using production systems

    Creator:
    Gazaly, Mohammed
    Abstract:
    This research work investigates the use of production systems as a model of parallel processing. The purpose of the model is to provide a suitable medium within which parallel processing systems can be systematically specified, analyzed, and designed. Furthermore, the model provides a suitable means for deriving implementations of synchronization...

  • Multithreaded virtual processor on DSM

    Creator:
    An, Ho Seok
    Abstract:
    Modern superscalar processors exploit instruction-level parallelism (ILP) by issuing multiple instructions in a single cycle because of increasing demand for higher performance in computing. However, stalls due to cache misses severely degrade the performance by disturbing the exploitation of ILP. Multiprocessors also greatly exacerbate the memory latency problem. In SMPs,...

  • Evaluation of scheduling heuristics for non-identical parallel processors

    Creator:
    Kuo, Chun-Ho
    Abstract:
    An evaluation of scheduling heuristics for non-identical parallel processors was performed. There has been limited research that has focused on scheduling of parallel processors. This research generalizes the results from prior work in this area and examines complex scheduling rules in terms of flow time, tardiness, and proportion of tardy...
