| |PDF (64 KB)

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»

The authors propose a novel output queuing ATM modular switch which has memoryless two-stage interconnection with disjoint-path topology. The goal of achieving the modular switch is to relax the limitation of VLSI implementation, to simplify interstage wiring and synchronization, furthermore to reduce complexity of the overall switch. A pure output queue is constructed by providing multipath in ea... 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 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»
