    The article discusses system-level issues and agent programming requirements that arise in the design of mobile agent systems. The authors describe several mobile agent systems to illustrate different approaches designers have taken in addressing these challenges. The following areas are discussed: agent mobility, naming, security issues, privacy and integrity, authentication, authorization and ac... View full abstract»

    A distributed system comprising networked heterogeneous processors requires efficient task-to-processor assignment to achieve fast turnaround time. Although reasonable heuristics exist to address optimal processor assignment for small problems, larger problems require better algorithms. The authors describe two new algorithms based on the A* technique which are considerably faster, are more memory... View full abstract»

  • Approaches for integrating task and data parallelism

    Languages that support task and data parallelism are highly general and can exploit both forms of parallelism in a single application. However, cleanly integrating the two forms of parallelism in a programming model is difficult. The authors describe four programming systems that attempt such an integration: Fx, Opus, data-parallel Orca, and Braid View full abstract»

    The authors demonstrate how their Minimal i386 Software Fault Isolation Tool (MiSFIT) protects applications from end user extensions written in otherwise unsafe languages. They also compare the performance of unprotected code with MiSFIT-protected versions. MiSFIT can be used to fault isolate dynamically linked extensions to Web browsers, operating system extensions, or client code linked to a dat... View full abstract»

    Distributed computing is moving into the mainstream because of advances in high speed networking and the Internet's explosive growth. Object oriented programming has become the dominating paradigm for developing reusable software. Distributed objects combine these two trends and are becoming increasingly popular. More and more software systems are built as distributed object applications, and they... View full abstract»

    PS (PVM simulator), is a simulator of PVM programs which lets users conduct performance prediction and analysis of distributed applications executed in heterogeneous and network computing environments. The article describes the tool and its development environment. As a prediction tool, the PS simulator lets developers obtain extrapolated performance data by estimating the behavior that a parallel... View full abstract»

    Load sharing improves the performance of distributed systems by moving work from heavily loaded to lightly loaded nodes. The author compares the performance of two principal load sharing policies under different circumstances, providing a generalized description of their behavior that holds true regardless of the specific system and workload models, and parameter values View full abstract»

    Providing video-over-wireless capability to mobile computing platforms results in several interesting challenges. Wireless networks provide less transmission bandwidth than hard wired networks. Because today's wireless local area network technology can provide only around 2 Mbps transmission rates, video compression is essential for transmitting to mobile devices. Due to increased user sensitivity... View full abstract»

    Remote procedure call systems have been around since around 1984 when they were first proposed (A.D. Birrell and B.J. Nelson, 1984). During the intervening 15 years, numerous evolutionary improvements have occurred in the basic RPC system, leading to improved systems-such as NCS (T.H. Dineen et al., 1987)-that offer programmers more functionality or greater simplicity. The Common Object Request Br... View full abstract»

    Although the development and use of Internet multimedia applications are increasing, the ability to manipulate and process multimedia information on the Internet is missing. The Internet's rich connectivity makes it an ideal blueprint for a high-performance computing system: millions and millions of heterogeneous computing nodes that can support open-standards protocols for communication and excha...
