You'll get subjects, question papers, their solution, syllabus - All in one app. We review the many performance metrics that have been proposed for parallel systems (i.e., program - architecture combinations). Let there be n different programs running on the system.The probability of execution of a program k is assumed to be $P_k,$ the time taken for that program is $T_k$.Then the weighted arithmetic mean $T_w$ is given by, $T_{W}=\frac{\sum_{k=1}^{n} T_{k} \cdot P_{k}}{n}$. Most scientific reports show performance im-provements of new techniques and are thus obliged to ensure repro-ducibility or at least interpretability. Then we can have a normalized metric known as geometric mean, represented as we can consider the speed of the program in terms of complexity, Let $M_{k}$ be the We may not have the execution time for every program in all cases. Performance Metrics of Parallel Applications: assess the performance of a parallel application normally by comparing the execution time with multiple processors and the execution time with just one processor. Abstract. Replica Management. We describe these metrics in terms of a graph of the application’s execution history, called a Program Activity Graph (or PAG). Utilization5. Therefore, more operations can be performed at a time, in parallel. Also explain use of it in parallel computing. Parallel Computer Architectureis the method of … It's the best way to discover useful content. Sorted by ... Scalability has been used extensively as a de facto performance criterion for evaluating parallel algorithms and architectures.

Message Oriented Communication, Stream Oriented Communication, 6.1 Desirable Features of global Scheduling algorithm, Task assignment Applied Chemistry 1. As we exit the era of Moore’s Law, high performance computing will require that programmers take advantage of parallel processors. Overview of Metrics This section describes the performance metrics that we used in this study. Typical code performance metrics such as the execution time and their acceleration are measured. 1.1 Parallel Computing, Parallel Architecture, Architectural Classification Scheme, Performance of Parallel Computers, Performance Metrics for Processors, Parallel Programming Models, Parallel Algorithms. Clients, Servers, Code Migration, 7.1 Clock Synchronization, Logical Clocks, Election Algorithms, Mutual However, a flaw in traditional performance metrics is that they rely on comparisons to serial performance with the same input. Amdahl's law can be modified, such that if there are some Detection rate, DR, which represents the ratio of true positive and the total nonself samples identified by detector set, where TP and FN are the tallies of true positive and false negative. In High Performance Computing, July 2015. The performance of a processor majorly depends on the clock speed Performance is an attribute that refers to the total elapsed time of an algorithm’s execution. Due to the increasing complexity of High Performance Computing (HPC) systems and applications it is necessary to maximize the insight of the performance data extracted from an application execution.
