    Summary form only given. This paper argues that, for high-speed networks such as ATM, it is important to use link-by-link flow control on a per virtual circuit (VC) basis. It can effectively control congestion and maximize network utilization. Three progressively memory-efficient, credit-based flow control schemes, called N123, N123+ and N23, are described, and simulation results of these schemes ... View full abstract»

    This paper examines the performance of synchronous checkpointing in a distributed computing environment with and without load redistribution. Performance models are developed, and optimum checkpoint intervals are determined. The analysis extends earlier work by allowing for multiple nodes, state dependent checkpoint intervals, and a performance metric which is coupled with failure-free performance... View full abstract»

    The authors study the use of non-volatile memory for caching in distributed file systems. This provides an advantage over traditional distributed file systems in that the load is reduced at the server without making the data vulnerable to failures. They show that small non-volatile write caches at the clients and the server are quite effective. They reduce the write response time and the load on t... View full abstract»

    The authors describe a fully distributed, parallel algorithm for ray-tracing problem. Load balancing is achieved through the use of comb distribution to roughly assign the same amount of pixels to each processor first, and then dynamically redistribute excessive loads among processors to keep each processor busy. In this model, there is no need for a master node to be responsible for dynamic sched... View full abstract»

    The authors present an object-oriented framework for constructing parallel implementations of stencil algorithms. This framework simplifies the development process by encapsulating the common aspects of stencil algorithms in a base stencil class so that application-specific derived classes can be easily defined via inheritance and overloading. In addition, the stencil base class contains mechanism... View full abstract»

    The PRAM model has been shown to be an optimal design for emulating both loose and tightly coupled multiprocessors for unit time operations. When virtual processors are required, multiplexing work to available processors is employed. This introduces a form of latency incurred by operating system overhead. Further complications arise when bandwidth creates bottlenecking of work units. G.E. Blelloch... View full abstract»

    The proposed distributed shared memory model is based on a data replication scheme that provides an environment for a collection of processes that interact to solve a parallel programming problem. In the implementation of the scheme the authors suppose that the replicas of the shared data are present at each node and that an appropriate coherence protocol for maintaining the consistency among the ...

    In order to exploit the latest advances in hardware technology, application developers need high-performance, easy-to-use cooperation tools that spun interconnections of standard hardware. Distributed shared memory has been proposed as such a cooperation tool, but performance problems have limited its usefulness. This paper argues that a new approach to distributed shared memory implementation can... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (548 KB)

    The authors present a simple MAC-level protocol for high-speed ring networks. The protocol is fair and its maximum achievable throughput does not deteriorate with the increasing propagation length of the ring. The proposed protocol operates on the so-called `spiral ring' topology, including the single-segment regular ring as a special case. It accommodates synchronous traffic automatically, withou...

    In general, a load balancing algorithm improves a system performance. Obviously, larger the difference between the task arrival rates at various processors, more the system is imbalanced and more improvement in the system performance is achieved using a load balancing algorithm. The existing works which have used an experimental technique to show the improvement in the system performance under a l... View full abstract»

    Multiprocessor systems should exist in the larger context of distributed systems, allowing multiprocessor resources to be shared by those that need them. Unfortunately, typical multiprocessor resource management techniques do not scale to large networks.

    A constructive learning algorithm dynamically creates a problem-specific neural network architecture rather than learning on a pre-specified architecture. The authors propose a parallel version of their recently presented constructive neural network learning algorithm. Parallelization provides a computational speedup by a factor of O(t) where t is the number of training examples. Distributed and p... View full abstract»
