performance metrics and measures in advanced computer architecture

SIMD computers: array processors & … 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 Computer Organization & Architecture Moazzam Ali Sahi Computer Performance Metrics, Measurement, & In general, the metrics are related to speed, accuracy, reliability and availability of services. The word performance in computer performance means “How well is the computer doing the work it is supposed to do?”. System Interconnect Architectures, Scalable Performance Metrics, and Measures. Performance Metric Metrics are criteria to compare the performances of a system. Operational metrics. From the Publisher: This book deals with advanced computer architecture and parallel programming techniques. The most widely used metric is the performance on the SPEC benchmark Geometric mean is better here (arithmetic mean can vary depending on the reference system). It basically depends on response time, throughput and execution time of a computer … Partitioning and Scheduling of Program, Flow Mechanisms of a Program. 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. Computer performance is the amount of work accomplished by a computer system. Metrics and Measures, Parallel Processing Applications, Speedup Performance Laws, Scalability Analysis and Approaches. Usually measures performance gains/losses over the reference system √ n ∏ i=0 The average time it takes to render a screen or page. Fall 2019 CS5513 Computer Architecture 8 Measuring Performance cont’d Normalized performance – Execution times are normalized to the performance of a reference system. Principles of scalable performance: 2 Performance metrics & measures, Speedup performance laws, Scalability analysis & approaches, Parallel Computer Architectures: 4 Design issues: communication models, interconnection networks, performance. Online application performance. Program Flow Mechanisms, System Interconnect Architectures, Principles of Scalable Performance, Performance. 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 Introduction to Theory of Parallelism.
