Textbook: “Computer Architecture: A Quantitative Approach,” Third Edition, John L. Hennessy and David A. Patterson, ISBN 1-55860-596-7A . How much more do I have to charge for it? Often when making comparisons in comp-arch, Program (or set of) is the same for two CPUs, So we can just directly compare CPIs and often, For a specific program running on a specific, MIPS Instruction count / (Execution Time, Faster execution time usually means faster MIPS, Program-dependent A single machine does not have, Easy to abuse Program used to get the MIPS, A higher MIPS rating in some cases may not mean, For a given program, two compilers produced the, The machine is assumed to run at a clock rate of, CPI1 (5 x 1 1 x 2 1 x 3) / (5 1 1) 10, CPU time1 ((5 1 1) x 106 x 1.43) / (100 x, CPI2 (10 x 1 1 x 2 1 x 3) / (10 1 1), CPU time2 ((10 1 1) x 106 x 1.25) / (100 x. r2*r3! /ExtGState << To view this presentation, you'll need to allow Flash. When we say 'one computer has better performance than another,' what do we mean? What if enhancement does not enhance everything? Lecture Slides; Based on Computer Organization & Design by Patterson/Hennessy ; COD Ch. endobj Management by objectivesA way to structure the subjective appraisal of a manager is to use management by objectives. They are all artistically enhanced with visually stunning color, shadow and lighting effects. Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions. This also includes: Operating … Computer performance is the amount of work accomplished by a computer system. Author uses word processor, drawing program, Workstations Standard Performance Evaluation, SPEC CPU2000 12 integer 14 floating-point, Separate average for integer (CINT2000) and FP. MULT r1,r2,r3! 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 Textbook.

Objective automatic MT evaluations ... Info gain for 2-gram and up is not meaningful. And, best of all, most of its cool features are free and easy to use. The class will focus on quantitative evaluation of design alternatives while considering design metrics such as performance and power dissipation. Performance Metrics by Brian H. Cameron With the increasing adoption of enterprise architecture (EA), organizations facemany challenges in how to measure and demonstrate the value that EAprovides to an enterprise.

CpE 442 Introduction to Computer Architecture The Role of Performance. - Review of Performance Evaluation and ISA Design. # r1 ! When we say one computer has better performance, want your job done as quickly as possible, want to do as many jobs per day as possible, Given a collection of machines, which has the, faced with design alternatives, which offers the, what hardware factors most impact performance of, Concord is 6.5 hours / 3 hours 2.2 times as, Boeing 747 is 286,700 p-mph / 178,200 p-mph 1.6, Boeing is 1.6 times (160) as fast in terms of, Concord is 2.2 times (220) as fast in terms of, Response Time Execution Time Latency Time in, Jobs per unit time (interest to the system, In discussing computer performance we are, To maximize performance, must minimize response, Performancex gt Performancey ? /F5 5 0 R There are many different ways to measure the performance of a network, as each network is different in nature and design.
