  • EM/sup 3/: a taxonomy of heterogeneous computing systems

    The field of heterogeneous computing is growing rapidly. New concepts and systems appear daily. Hence, it is important to fit each new contribution into its proper place in the puzzle called heterogeneous computing. This is possible only if an adequate taxonomy/classification exists, one that can show whether or not a new system is heterogeneous, and if so, what kind of heterogeneity it exhibits. We propose a new taxonomy that shows the relative position of each and every heterogeneous system in the overall computer systems world. The proposed taxonomy is intended to be both broad enough to encompass all existing heterogeneous systems and simple enough to be easily accepted. Consequently, our taxonomy includes only four classes of computer systems. We propose that computer systems be classified as follows: SESM (single execution mode, single machine model); SEMM (single execution mode, multiple machine models), MESM (multiple execution modes, single machine model), and MEMM (multiple execution modes, multiple machine models).

  • A software system evaluation framework

    The objective of a software system evaluation framework is to assess the quality and sophistication of software from different points of view. The framework explicitly links process and product aspects with the ultimate utility of systems and it provides a basic set of attributes to characterize the important dimensions of software systems. We describe such a framework and its levels of categorization, and we analyze examples of project classifications. Then we draw some conclusions and present ideas for further research. This evaluation framework assesses a software system's quality by consolidating the viewpoints of producers, operators, users, managers, and stakeholders View full abstract»

  • Task scheduling in multiprocessing systems

    Publication Year: 1995 , Page(s): 27 - 37

    The complex problem of assigning tasks to processing elements in order to optimize a performance measure has resulted in numerous heuristics aimed at approximating an optimal solution. This article addresses the task scheduling problem in many of its variations and surveys the major solutions. The scheduling techniques we discuss might be used by a compiler writer to optimize the code that comes out of a parallelizing compiler. The compiler would produce grains of sequential code, and the optimizer would schedule these grains such that the program runs in the shortest time View full abstract»

  • Parallel computing in the undergraduate curriculum

    Publication Year: 1995 , Page(s): 51 - 56
    Cited by:  Papers (4)
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (672 KB)  

    Computer science students need to understand parallel computing, since it may become an integral part of their own careers. The best way to accomplish this is to integrate parallel computing concepts throughout the entire curriculum, from the introductory level up. As parallel computing becomes a part of several courses, it need not displace large segments of material that are currently in these courses; each course can contribute a small amount to the overall objective of understanding parallel computing. The paper presents a sample curriculum View full abstract»

  • A case for symmetrical bandwidth

    Publication Year: 1995 , Page(s): 93 - 94
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (236 KB)  

    The paper discusses one of the significant challenges facing broadband telecommunications service providers, (especially the cable television industry) that is, the issue of symmetrical versus asymmetrical bandwidth deployment for coaxial-based data services to the residential marketplace. Symmetrical networks offer the same bandwidth capacity in both directions, whereas asymmetrical networks offer greater bandwidth capacity in one direction. For anyone who extensively uses information networks (for example, the Internet) the solution is simple: more bandwidth to enable higher performance network access View full abstract»

  • The Info Age law firm

    Publication Year: 1995 , Page(s): 86 - 87
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (196 KB)  

    This paper is, in part, a response to Lewis, see ibid., September, p.8-10 (1995) which says that lawyers do not understand technology and therefore cannot keep pace with change. Lewis also states that technology will be based on speed and customization rather than legal rights. However, he neglects one theorem: where there is money to be made, there is usually someone to make it. In this regard, I submit that some law firms will not only survive in the Info Age but will even thrive and flourish, as survival of the fittest becomes a truism. A significant contributing factor will be superior technology that lets lawyers do more in less time. These law firms, however, may not have the same look and feel, as they do today View full abstract»

  • VMW: a visualization-based microarchitecture workbench

    Superscalar processor design requires increasingly sophisticated software tools. The visualization-based microarchitecture workbench described in the paper addresses weaknesses common to most performance simulators: the lack of retargetability, visualization support, and interactive control. VMW provides a multifunction workbench for aiding designers of modern superscalar processors. It facilitates rigorous machine specification by providing specification templates at both the architecture and microarchitecture levels View full abstract»

  • Collective communication in wormhole-routed massively parallel computers

    Most MPC networks use wormhole routing to reduce the effect of path length on communication time. Researchers have exploited this by designing ingenious algorithms to speed collective communication. Many projects have addressed the design of efficient collective communication algorithms for wormhole-routed systems. By exploiting the relative distance-insensitivity of wormhole routing, these new algorithms often differ fundamentally from their store-and-forward counterparts. We examine software and hardware approaches to implementing collective communication operations. Although we emphasize methods in which the underlying architecture is a direct network, such as a hypercube or mesh, as opposed to an indirect switch-based network, several approaches apply to systems of either type. We illustrate several issues arising in this research area and describe the major classes of algorithms proposed to solve these problems View full abstract»
