This paper addresses the problem of supporting communications in parallel computing applications over ATM networks. We propose a mechanism specifically conceived for optimizing the cost-performance tradeoff in fairly long parallel executions. The proposed mechanism relies on a modified version of the loss recovery procedure of SSCOP, which is enhanced by means of a more intensive exploitation of ATM service categories in order to reduce the occurrence of cell loss. For this purpose, we make use
more &raquo; ... of both the UBR and ABR service categories, with ABR being only introduced in the periods of high latency. These periods are determined by periodically monitoring the experienced latency. This approach can achieve equivalent latency as the plain ABR service but with a use of this service of only 30%-70% of the parallel computing traffic, depending on the load of the network and the characteristics of the application.
