The goal of this paper is to discuss the current trends on High Performance Distributed Computing (HPDC) environments supported by ATM networks. The adoption of a high speed network like ATM to overcome the bandwidth limitation induced by traditional LAN technologies has moved the bottleneck to the host. The challenge of ATM-based HPDC systems is to(More)
In this paper, we address the problem of supporting High Performance Distributed Computing (HPDC) applications running over ATM networks. For this purpose, we consider a logically separate subnetwork for these applications. After presenting an architectural reference model for the HPDC subnetwork and distinguishing which functions should be installed over(More)
This paper addresses the problem of supporting communications in parallel computing applications over ATM networks. We propose a mechanism speciically conceived for optimizing the cost-performance tradeoo in fairly long parallel executions. The proposed mechanism relies on a modiied version of the loss recovery procedure of SSCOP, which is enhanced by means(More)

The aim of this paper is to study the behavior of two characteristics of ATM video traffic which are critical on the quality degradation introduced by the network. These characteristics are cell loss and delay jitter. This study takes the burstiness of the traffic, due to its variable-rate nature, as a reference. Cell loss can alter the characteristics of(More)

The interest in LAN interconnection through high speed networks is becoming increasingly important because new applications with stronger timing and bandwidth requirements are arising. This paper studies the end-to-end performance achieved when routing FDDI traffic through an ATM network. Traffic consists of merged IP and coded, packetized video. A main(More)
In this paper, we address the problem of supporting network-based parallel computing, usually known in the literature as High Performance Distributed Computing (HPDC), over ATM networks. For this purpose, we consider a logically separate subnetwork for HPDC applications. After presenting an architectural reference model for the HPDC subnetwork and(More)
