Performance analysis can be one of the most important elements in the design cycle of a computer system. It can also be very important after the fact to influence future designs. But only if it is done right. If done wrong, it can be more harmful than if not done at all.

3:45 - 5:15     Panel Discussion

Quantitative evaluation of next-generation computer architectures and processor enhancements is possible only by running simulations. However, since the insights that are gained through simulation are predicated on the accuracy of the simulation results, and since the design decisions for future processor architectures -- which cost billions of dollars to design and implement -- are based on those insights, periodic examination of the simulation process becomes a necessity, rather than a luxury. Accordingly, this panel discusses the deficiencies of existing simulators, benchmarks, and simulation methodologies and techniques, and, in addition, what future directions are available for each.

Day 3 - March 12 (Friday)




  9:00 - 12:30     Morning Session

          Lieven Eeckhout (Ghent University, Belgium)


Designing a high performance microprocessor is extremely time-consuming taking at least several years. An important part of this design effort is architectural simulation which defines the microarchitecture or the organization of the microprocessor. The reason why these simulations are so time-consuming is fourfold: (i) the architectural design space is huge, (ii) the number of benchmarks the microarchitecture needs to be evaluated with, is large, (iii) the number of instructions that need to be simulated per benchmark is huge as well, and (iv) simulators are becoming relatively slower due to the increasingly complex designs of current high performance microprocessors. In this tutorial, we will discuss these issues and propose a solution for each of them. As such, we will present an architectural simulation framework for designing high performance microprocessors which reduces the total simulation time by several orders of magnitude without sacrificing accuracy. This is done by combining several recently proposed techniques, such as statistical simulation, representative workload design using statistical data analysis techniques, trace sampling and reduced input sets.  



Lieven Eeckhout obtained his Master and PhD in Computer Science and Engineering from Ghent University, Belgium, in 1998 and 2002, respectively. He is currently working as a Postdoctoral Researcher at the same university through a grant from the Fund for Scientific Research—Flanders (FWO Vlaanderen). His research interests include computer architecture, performance evaluation and workload characterization. He has published numerous papers in various high quality journals (IEEE Computer, IEEE Micro and Journal of Instruction-Level Parallelism) and conferences (PACT, OOPSLA, etc.). 

12:30 -   2:00     Lunch


   2:00 -  5:30     Afternoon Session

          Wayne Wolf (Princeton University)


This tutorial will cover architectures and compilers for multimedia systems. Multimedia applications impose real-time constraints on continuous media; they also include a surprisingly wide variety of algorithms. Many multimedia systems also operate under power/energy constraints. As such, multimedia computing systems are an important area of interest for ISPASS. This tutorial will target individuals with experience in hardware and software but who have limited expertise in multimedia. We will start with an introduction to multimedia algorithms such as video and audio compression since the characteristics of these algorithms help to shape measurement strategies and architectural decisions. We will then cover modern multimedia architectures and compilation techniques relevant to those architectures. We will conclude with a case study drawn from our own research---the design of a multiprocessor system-on-chip for real-time gesture recognition. 



Wayne Wolf is professor of electrical engineering at Princeton University. Before joining Princeton, he was with AT&T Bell Laboratories, Murray Hill, New Jersey. He received the B.S., M.S., and Ph.D. degrees in electrical engineering from Stanford University in 1980, 1981, and 1984, respectively. His research interests include embedded computing, VLSI systems, and multimedia information systems. He is author or co-author of over 250 technical publications. He is the author of Computers as Components and Modern VLSI Design (for which he won the ASEE/CSE and HP Frederick E. Terman Award). Wolf has been elected to Phi Beta Kappa and Tau Beta Pi. He is a Fellow of the IEEE and ACM and a member of the SPIE and ASEE.




The workshop will be held at the Hotel Renaissance at Austin.
