MICROPROCESSOR www.MPRonline.com THE REPORTINSIDER’S GUIDE TO MICROPROCESSOR HARDWARE EEMBC’S MULTIBENCH ARRIVES CPU Benchmarks: Not Just For ‘Benchmarketing’ Any More By Tom R. Halfhill {7/28/08-01} Imagine a world without measurements or statistical comparisons. Baseball fans wouldn’t fail to notice that a .300 hitter is better than a .100 hitter. But would they welcome a trade that sends the .300 hitter to Cleveland for three .100 hitters? System designers and software developers face similar quandaries when making trade-offs EEMBC’s role has evolved over the years, and Multi- with multicore processors. Even if a dual-core processor Bench is another step. Originally, EEMBC was conceived as an appears to be better than a single-core processor, how much independent entity that would create benchmark suites and better is it? Twice as good? Would a quad-core processor be certify the scores for accuracy, allowing vendors and customers four times better? Are more cores worth the additional cost, to make valid comparisons among embedded microproces- design complexity, power consumption, and programming sors. (See MPR 5/1/00-02, “EEMBC Releases First Bench- difficulty? marks.”) EEMBC still serves that role. But, as it turns out, most The Embedded Microprocessor Benchmark Consor- EEMBC members don’t openly publish their scores. Instead, tium (EEMBC) wants to help answer those questions. they disclose scores to prospective customers under an NDA or EEMBC’s MultiBench 1.0 is a new benchmark suite for use the benchmarks for internal testing and analysis. measuring the throughput of multiprocessor systems, Partly for this reason, MPR rarely cites EEMBC scores including those built with multicore processors. -
Load Testing, Benchmarking, and Application Performance Management for the Web
Published in the 2002 Computer Measurement Group (CMG) Conference, Reno, NV, Dec. 2002. LOAD TESTING, BENCHMARKING, AND APPLICATION PERFORMANCE MANAGEMENT FOR THE WEB Daniel A. Menascé Department of Computer Science and E-center of E-Business George Mason University Fairfax, VA 22030-4444 [email protected] Web-based applications are becoming mission-critical for many organizations and their performance has to be closely watched. This paper discusses three important activities in this context: load testing, benchmarking, and application performance management. Best practices for each of these activities are identified. The paper also explains how basic performance results can be used to increase the efficiency of load testing procedures. infrastructure depends on the traffic it expects to see 1. Introduction at its site. One needs to spend enough but no more than is required in the IT infrastructure. Besides, Web-based applications are becoming mission- resources need to be spent where they will generate critical to most private and governmental the most benefit.

Overview of the SPEC Benchmarks
9 Overview of the SPEC Benchmarks Kaivalya M. Dixit IBM Corporation “The reputation of current benchmarketing claims regarding system performance is on par with the promises made by politicians during elections.” Standard Performance Evaluation Corporation (SPEC) was founded in October, 1988, by Apollo, Hewlett-Packard,MIPS Computer Systems and SUN Microsystems in cooperation with E. E. Times. SPEC is a nonprofit consortium of 22 major computer vendors whose common goals are “to provide the industry with a realistic yardstick to measure the performance of advanced computer systems” and to educate consumers about the performance of vendors’ products. SPEC creates, maintains, distributes, and endorses a standardized set of application-oriented programs to be used as benchmarks. 489 490 CHAPTER 9 Overview of the SPEC Benchmarks 9.1 Historical Perspective Traditional benchmarks have failed to characterize the system performance of modern computer systems. Some of those benchmarks measure component-level performance, and some of the measurements are routinely published as system performance. Historically, vendors have characterized the performances of their systems in a variety of confusing metrics. In part, the confusion is due to a lack of credible performance information, agreement, and leadership among competing vendors. Many vendors characterize system performance in millions of instructions per second (MIPS) and millions of floating-point operations per second (MFLOPS). All instructions, however, are not equal. Since CISC machine instructions usually accomplish a lot more than those of RISC machines, comparing the instructions of a CISC machine and a RISC machine is similar to comparing Latin and Greek. 9.1.1 Simple CPU Benchmarks Truth in benchmarking is an oxymoron because vendors use benchmarks for marketing purposes. -
Opportunities and Open Problems for Static and Dynamic Program Analysis Mark Harman∗, Peter O’Hearn∗ ∗Facebook London and University College London, UK
1 From Start-ups to Scale-ups: Opportunities and Open Problems for Static and Dynamic Program Analysis Mark Harman∗, Peter O’Hearn∗ ∗Facebook London and University College London, UK Abstract—This paper1 describes some of the challenges and research questions that target the most productive intersection opportunities when deploying static and dynamic analysis at we have yet witnessed: that between exciting, intellectually scale, drawing on the authors’ experience with the Infer and challenging science, and real-world deployment impact. Sapienz Technologies at Facebook, each of which started life as a research-led start-up that was subsequently deployed at scale, Many industrialists have perhaps tended to regard it unlikely impacting billions of people worldwide. that much academic work will prove relevant to their most The paper identifies open problems that have yet to receive pressing industrial concerns. On the other hand, it is not significant attention from the scientific community, yet which uncommon for academic and scientific researchers to believe have potential for profound real world impact, formulating these that most of the problems faced by industrialists are either as research questions that, we believe, are ripe for exploration and that would make excellent topics for research projects. boring, tedious or scientifically uninteresting. This sociological phenomenon has led to a great deal of miscommunication between the academic and industrial sectors. I. INTRODUCTION We hope that we can make a small contribution by focusing on the intersection of challenging and interesting scientific How do we transition research on static and dynamic problems with pressing industrial deployment needs. Our aim analysis techniques from the testing and verification research is to move the debate beyond relatively unhelpful observations communities to industrial practice? Many have asked this we have typically encountered in, for example, conference question, and others related to it. -

A Look Inside: TPF Inside: A Look President’s Message This has been a great year for The Perl Foundation. Thanks to the generosity of our donors and corporate partners, the commitment of our volunteers, and the vitality and energy of our community, we have been able to continue in our mission to advance the Perl programming language. As you know, TPF depends on donations, both of time and money, to operate. These donations have made it possible for us to provide financial support to key developers of Perl 5 and Perl 6, to continue our efforts in protecting our trademark, and to support many community programs. One of the pillars of Perl is its community. We recently launched an initiative, the Community Advocacy Committee, targeting the growth and health of the Perl community. With the help of this committee we plan to not only improve communication within our own community but to expand our links with other F/OSS communities. This year has been one pointing to a great future for Perl and those who use it. -
