Tutorial 1

Raj Jain, Washington University, St. Louis, EUA

Title: Computer Systems Performance Analysis: Design of Experiments

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.

Title: Peer-to-Peer Networking: State of the Art and Research Challenges

The past few years have witnessed the emergence of Peer-to-Peer (P2P) systems as a means to further facilitate the formation of communities of interest over the Internet in all areas of human life including technical/research, cultural, political, social, entertainment, etc. P2P technologies involve data storage, discovery and retrieval, overlay networks and application-level routing, security and reputation, measurements and management. This tutorial will give an appreciation of the issues and state of the art in Peer-to-Peer Networking. It will introduce the underlying concepts, present existing architectures, highlight the design requirements, discuss the research issues, compare existing approaches, and illustrate the concepts through case studies. The ultimate objective is to provide the tutorial attendees with an understanding of the issues inherent to the design, deployment and operation of large-scale P2P systems.
