This is the simple mean calculated as the sum of times required for every program However, for many, scalability has theoretical interests only since it does not reveal execution time. 02 Pipeline Processing. Less elapsed time means higher performance. Filter × … Unless you have some idea about the performance metrics, you will not be able to decide which will be the best performance improvement that you can think of and which will lead to least cost and which will give you the best cost performance ratio. Exclusion, Distributed Mutual Exclusion-Classification of mutual It is given by, $\begin{aligned} R_{G} &=\sqrt[n]{\pi R_{k}}, k=1,2, \ldots, n \\ Where \ R_{k} &=\frac{\text { Time on CPU under consideration }}{\text { Time on reference } C P U} \end{aligned}$. However, a flaw in traditional performance metrics is that they rely on comparisons to serial performance with the same input. These include the many vari- ants of speedup, efficiency, and isoefficiency. Applied Mathematics 4 . File-Caching Schemes, File Replication, Network File System(NFS), Sorted by ... Scalability has been used extensively as a de facto performance criterion for evaluating parallel algorithms and architectures.
