Performance Metrics and Scalability Analysis October 10 – 11, 2002, Par.Comp Workshop at IIT-Delhi 2 v Requirements in performance and cost v Performance metrics v Work load and speed metrics v Communication overhead measurement Analysis v Theoretical concepts on Performance and Scalability • Phase Parallel Model It basically depends on response time, throughput and execution time of a computer … The average time it takes to render a screen or page. Computer Organization & Architecture Moazzam Ali Sahi Computer Performance Metrics, Measurement, & In general, the metrics are related to speed, accuracy, reliability and availability of services. Metrics and Measures, Parallel Processing Applications, Speedup Performance Laws, Scalability Analysis and Approaches. The basic characteristis of a computer system that we typically need to measure are: I a count of how many times an event occurs, I the duration of some time interval, and Online application performance. From the Publisher: This book deals with advanced computer architecture and parallel programming techniques. Introduction to Theory of Parallelism. –What computer architecture –Why it is important to study –Organization and anatomy of computers –Impact of microelectronics technology on computers –Evolution and generations of the computer industry •This Lecture –Cost considerations in computer design –Why measuring performance is important –Different performance metrics Fall 2019 CS5513 Computer Architecture 8 Measuring Performance cont’d Normalized performance – Execution times are normalized to the performance of a reference system. View Week7_Lecture1.pdf from CS MISC at COMSATS Institute of Information Technology, Lahore. Computer performance is the amount of work accomplished by a computer system. SIMD computers: array processors & … Geometric mean is better here (arithmetic mean can vary depending on the reference system). The word performance in computer performance means “How well is the computer doing the work it is supposed to do?”. Advanced Computer Architecture Lab EECS Department, University of Michigan {blj,tnm}@umich.edu Abstract This report explains what it means to characterize the performance of a computer , and which methods are appro-priate and inappropriate for the task. The material is suitable for use as a textbook in a one-semester graduate or senior course,offered by Computer Science,Computer Engineering,Electrical Engineering,or Industrial Engineering programs.
