Abstract
The design, analysis and development of parallel and distributed applications in High Performance Computing and Communication (HPCC) Systems are still very challenging tasks. Therefore, there is a great need for an integrated multilevel analysis methodology to assist in designing and analyzing the performance of both existing and proposed new HPCC systems. Currently, there are no comprehensive analysis methods that address such hierarchical modeling approach for analyzing the end-to-end performance of an application running on an HPCC system. The overall system is partitioned into application level, protocol level and network level. Functions at each level are modeled using queueing networks. The approach enables the designer to study performance for different types of networks and protocols and different design strategies. In this paper we use video-on-demand as an application example to show how our approach can be used to analyze the performance of such an application.
