This paper investigates the execution behaviors of parallel sorting algorithms on an experimental multiprocessor (KuPP) and compares with predicted performance under LogP and BSP (Bulk Synchronous Parallel) models. Since the communication overhead is considered a primary candidate for improvement, a few schemes are devised and experimented on KuPP to reduce the time spent in communication, thus to enhance the overall performance. The authors believe the ideas can be adopted in other high-performance parallel computers
