    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 concerns itself with efforts to extend multicomputer libraries to a hierarchical, heterogeneous network environment. Two classes of support for such libraries are discussed: first, the message-passing features needed to establish groups of communicating processes, and communication contexts within which libraries can safely work. Second, it discusses message-passing primitives that enca... 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. The Prospero Resource Manager (PRM) is a scalable resource allocation system that supports the allocation of processing resources in large networ... View full abstract»

    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»

    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 distributed system is becoming increasingly popular, and this produces the need for more sophisticated distributed control techniques. The authors present a method for distributed control using simple finite state automata. Each of the distributed entities is `controlled' by its associated automaton, in the sense that the entity examines the state of the automaton to determine its behavior. Th... View full abstract»
