Multiprocessors have been widely used in achieving high performance computation. In a multiprocessor, applications are implemented with processes executing on multiple processors and cooperating with each other. It is hoped that, by using multiple processors, multiplied performance improvement can be obtained. Ideal speedup, however, can hardly be achieved(More)
