There are several metrics that characterize the performance of a parallel system, such as, parallel execution time, speedup and eeciency. A number of properties of these metrics have been studied. For example, it is a well known fact that given a parallel architecture and a problem of a xed size, the speedup of a parallel algorithm does not continue to increase with increasing number of processors. It usually tends to saturate or peak at a certain limit. Thus it may not be useful to employ more… CONTINUE READING
