    The basic properties of object orientation and their application to heterogeneous, autonomous, and distributed system to increase interoperability ar examined. It is argued that object-oriented distributed computing is a natural step forward from client-server systems. To support this claim, the differing levels of object-oriented support already found in commercially available distributed systems... View full abstract»

    Jade, a high-level parallel programming language for managing coarse-grained parallelism, is discussed. Jade simplifies programming by providing sequential-execution and shared-address-space abstractions. It is also platform-independent; the same Jade program runs on uniprocessors, multiprocessors, and heterogeneous networks of machines. An example that illustrates how Jade programmers express irr...

  • An architectural framework for supporting heterogeneous instruction-set architectures

    Publication Year: 1993, Page(s):39 - 56
    Cited by:  Papers (25)  |  Patents (58)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1840 KB)

    An architectural framework that allows software applications and operating system code written for a given instruction set to migrate to different, higher performance architectures is described. The framework provides a hardware mechanism that enhances application performance while keeping the same program behavior from a user perspective. The framework is designed to accommodate program exception... View full abstract»

    Cooperative Processes Software (CPS), a parallel programming toolkit developed at Fermilab for processing CPU-intensive experimental data in the area of high-energy physics, is described. CPS allows physicists to solve computationally intensive problems on a collection of reduced-instruction-set-computer (RISC) workstations that work in parallel to provide solutions within a reasonable time frame....

  • A distributed heterogeneous supercomputing management system

    Publication Year: 1993, Page(s):78 - 86
    Cited by:  Papers (71)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1273 KB)

    A general management framework for distributed heterogenous supercomputing systems (DHSSs) that is based on an application-characterization technique is presented. The technique uses code profiling and analytical benchmarking of supercomputers. An optimal scheduling of tasks in these systems is an NP-complete problem. The use of network caching to reduce the complexity associated with the scheduli... View full abstract»

    The authors' experiences with visualization and debugging of parallel virtual machine (PVM) applications and two of the tools they have devised to facilitate these tasks are described. One of the tools is a graphical monitoring package called Xab that can visually display PVM activities inside an application running across a network. The other is a graphical programming environment called Hence, w... View full abstract»
