Título: Computer Systems Performance Analysis: Design of Experiments

Horário: 30 de maio - 14h às 18h

Performance often depends upon more than one factor such as the system and the workload. Proper analysis requires that the effects of each factor be isolated from those of others so that meaningful statements can be made about different levels of the factor, for instance, different systems. Such analysis is the main topic of this tutorial. The techniques presented in this part will enable you to do the following:

  • Design a proper set of experiments for measurement or simulation.
  • Develop a model that best describes the data obtained.
  • Estimate the contribution of each alternative (for example, each processor and each workload) to the performance.
  • Isolate the measurement errors.
  • Estimate confidence intervals for model parameters.
  • Check if the alternatives are significantly different.
  • Check if the model is adequate.

The goal of a proper experimental design is to obtain the maximum information with the minimum number of experiments. This saves considerable labor that would have been spent gathering data.

The tutorial is based on Part IV of my book The Art of Computer Systems Performance Analysis: Techniques for Experimental Design, Measurement, Simulation, and Modeling. The techniques of the course can be used to analyze and compare any type of systems including algorithms, protocols, network, or database systems.


Professor Raj Jain is a Fellow of IEEE, a Fellow of ACM, a winner of ACM SIGCOMM Test of Time award, CDAC-ACCS Foundation Award 2009, Hind Rattan Award 2011, and ranks among the top 50 in Citeseer's list of Most Cited Authors in Computer Science. Dr. Jain is currently a Professor of Computer Science and Engineering at Washington University in St. Louis. Previously, he was one of the Co-founders of Nayna Networks, Inc - a next generation telecommunications systems company in San Jose, CA. He was a Senior Consulting Engineer at Digital Equipment Corporation in Littleton, Mass and then a professor of Computer and Information Sciences at Ohio State University in Columbus, Ohio. He is the author of `` Art of Computer Systems Performance Analysis,'' which won the 1991 ``Best-Advanced How-to Book, Systems'' award from Computer Press Association. His fourth book entitled " High-Performance TCP/IP: Concepts, Issues, and Solutions," was published by Prentice Hall in November 2003. He is a co-editor of " Quality of Service Architectures for Wireless Networks: Performance Metrics and Management," published in April 2010. Prof. Jain's papers have been widely referenced and he is known for his research on congestion control and avoidance, traffic modeling, performance analysis, and error analysis. Google Scholar lists over 12500+ citations to his publications. He is a co-inventor of the DECbit scheme, which has been implemented in various forms in DECnet, OSI, Frame Relay, and ATM Networks (Explicit Forward Congestion Indication. His team has developed several switch algorithms for explicit rate-based congestion avoidance in ATM networks. A distinguishing factor of his research is its relevance to the Industry. As a faculty member, Dr. Jain actively participates in industry forums like WiMAX Forum, IEEE Standards group, ATM Forum and Internet Engineering Task Force and has made over 200 contributions that ensured that his research was implemented and not just published as papers. Based on his active participation in the computer industry, Dr. Jain was awarded 1999 siliconindia Leadership Awards for Excellence and Promise in Business and Technology. Raj Jain has served on the Board of Technical Advisors to a dozen Silicon Valley start ups including Nexabit Networks, Westborough, MA acquired by Lucent Corporation. (March 1997-1999), Amber Networks, Fremont, CA acquired by Nokia (1999-2001). He was the keynote speaker at COMSNETS 2011, ANTS 2010, MICS 2010, ADCOM 2009, NBiS 2009, NetArch 2009, ICON 2008, ACM Multimedia 2008, ICCBN 2008, ICCCE 2008, AccessNets 2007, and a dozen other conferences. He is the Co-Editor in Chief of ICST Transactions on Networking and Communications and is on the Editorial Boards of Journal of High Speed Networks (USA), Mobile Networks and Applications (MONET), International Journal of Virtual Technology and Multimedia (IJVTM) (UK), International Journal of Wireless and Optical Communications (IJWOC), and International Journal of Communication Networks and Distributed Systems (IJCNDS), ICST Transactions on Mobile Communications and Applications, ICST Transactions on Information-Centric Networking, and on the advisory boards of Global Science and Technology Forum (GSTF), Singapore, Central European Journal of Computer Science (Poland) and Journal of Communications (Finland). He has served as a Distinguished Lecturer for the IEEE Communications Society (1997, 1999-2006), ACM Lecturer (1991-97), IEEE Computer Society Distinguished Visitor (1993-96), Vice-Chair of ACM SIGCOMM (1991-95), Chair of TIA/SCD/CIS Working Group on ATM Traffic Management (1996-1998), Editor of the WiMAX Forum System Evaluation Methodology (2005-2008), Editor of ATM Forum Performance Testing Specification (1996-1998). He has served in the program committees or advisory committees of over 170+ conferences.
