    Currently, a variety of the MBONE video tools provide video conferencing capabilities on different platforms and with a variety of compression algorithms. However most of these tools lack the ability to interact with other media agents that might be used during a conferencing session. Such interaction is required, for example, for achieving lip synchronisation between audio and video streams or fo... View full abstract»

    This paper describes the design of a distributed system built using Java that supports peer-to-peer communication among processes spread across a network. We identify the requirements of a software layer that supports distributed computing, and we propose a design that meets those requirements. Our primary concerns are (I) the identification, specification, and implementation of software component... View full abstract»

    Argues that future computing environments will be collaboration-oriented, globally distributed and computation/information-rich. These environments will be accessed via multiple interface devices. As we move from a desktop-centric computing model to a network-centric model, new approaches in the way software and data are handled will need to be developed. In this article, we outline the requiremen... View full abstract»

    The simulation of many-body, many-particle systems has a wide range of applications in areas such as biophysics, chemistry, astrophysics, etc. It is known that the force calculation contributes 90% of the simulation time. This is mainly due to the fact that the total number of interactions in the force is O(N/sup 2/), where N is the number of particles in the system. The fast multipole algorithm p...

    The modest I/O configurations and file system limitations of many current high-performance systems preclude solution of problems with large I/O needs. I/O hardware and file system parallelism is the key to achieving high performance. We analyze the I/O behavior of several versions of two scientific applications on the Intel Paragon XP/S. The versions involve incremental application code enhancemen... View full abstract»

    In order to use networks of workstations in parallel processing applications, several schemes have been devised to allow processes on different, possibly heterogeneous, platforms to communicate with one another. The Message-Passing Interface (MPI) is one such scheme that allows for message-passing across different architectures. The MPI specification does not make provisions for the migration of a...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1043 KB)

    The remote procedure call (RPC) paradigm has been a favorite of programmers who write distributed programs because RPC uses a familiar procedure call abstraction as the sole mechanism of remote operation. The abstraction helps to simplify programming tasks, but this does not mean that the resulting program's RPC-based flow of control will be anything close to ideal for high performance. The purpos...

    The goal of this work is to simplify parallel application development, and thus ease the learning barriers faced by non-experts. It is especially useful where there is little data-parallelism to be recognized by a compiler. The applications programmer need learn the intricacies of only one primary subroutine in order to get the full benefits of the parallel interface. The applications programmer d...

    Networks of workstations provide an economic solution for scalable computing because they do not require specialized components. Even though recent advances have shown that it is possible to obtain high bandwidth between applications, interconnect latency remains a serious concern.

    Many parallel applications are designed to conceal parallelism from the user. We investigate a different approach where the user controls many tasks running in parallel. The idea is to let a user accomplish his goal more quickly by trying competing alternatives in parallel (or-parallelism) and by working on subgoals in parallel (and-parallelism). To help the user manage a large number of parallel ... View full abstract»
