A Concurrent Multi Target Tracker: Benchmarking and Portability

With the current advances in computing and network technology and software, the gap between parallel and distributed computing environment is gradually becoming narrower. Consequently, parallel programs run on parallel as well as distributed systems. However, programming and porting complex applications to such environment is challenging task and not well understood. In this paper, we use a concurrent multi target tracker as a running example to analyze and evaluate performance of two different parallel implementations on parallel and distributed systems. We have benchmarked both these implementations on different architectures that vary from a network of worksta?? tions{SUN, IBM RS6000) to parallel computers (CM5, iPSC 860) using different parallel/distributed message passing tools{PVM, p4, EXPRESS).
