Performance Evaluation Laboratory


/ Kohei Otsuyama / Assistant Professor
/ Hiroshi Toyoizumi / Assistant Professor

The performance evaluation laboratory is part of the Department of Software, the University of Aizu. The laboratory mission in the broad sense is to contribute to:

  1. Theoretical Aspects of Performance Evaluation of Computer and Communications Systems
  2. Tools and Techniques for the Performance Evaluation of Computer and Communications Systems
  3. Applications to Computer and Communications Systems : Evaluations and Performance

During fiscal year 1998 (Apr.1998 - Apr.1999) the laboratory was composed of two faculty members. Current research interests include:

  1. Project PEHW: Reconfigurable Computing Performance Evaluation Reconfigurable computing is increasingly used in various applications in telecommunications and computer systems. Our focus here is to investigate tools and techniques which allows quick performance evaluation of reconfigurable computing systems. Both analytical and simulations approach are investigated.
  2. Workload characterization of intelligent systems An increasing number of applications make use of various intelligent techniques such as: neural networks, fuzzy logic and evolutionnary computation along with their combinations. Unfortunatly, little work have been done so far on those workloads and their computationnal requirements. Our own investigations have shown that popular benchmarks such SPEC are not relevant for this type of workloads.
  3. Rapid Prototyping and Performance Evaluation using Reprogrammable Devices This research is concerned with the rapid prototyping and performance evaluation of systems using reprogrammable devices (PLD, FPGA). This is a hardware approach to performance evaluation.
  4. CoEvolvable Hardware Workbench This project addresses the problems of Cooperative coevolution using reprogrammable hardware devices.

Performance Evaluation Laboratory faculty members are involved in both the Graduate School of Engineering Graduate Department of Information Systems (2nd field of studies, Computer Organization and Parallel Processing) and the Graduate Department of Computer Systems (8th field of studies, Computer Network Systems). Teachings includes: Parallel and Distributed Computer Architectures, Fuzzy and Neural Processor Design. At the undergraduate level faculty members are involved in computer architecture, performance evaluation and programming courses.

From July 1999, the Performance Evaluation Laboratory includes Dr. Hiroshi Toyoizumi. Dr. Hiroshi Toyoizumi research interests are in the study of the theories of applied probability and stochastic processes to use in performance evaluation.

The Performance Evaluation Laboratory was involved in various seminars held in the University through invited speakers.
