Mission:

To study and develop methods and mechanisms that promote consistent performance in distributed computing systems.


    Research Questions:
  1. Can performance consistency be achieved and maintained in large distributed computing systems? 
  2. What are the contributing factors that undermine consistent systemic performance? 
  3. What subsystems are affected most by these factors?
  4. How can the system as a whole achieve consistent performance?
Large distributed computing systems are composed of subsystems that do not know much about each other. Our  research in this area seeks to understand the system dynamics and how the subsystems might better interact with each other by coordinated adaptation so the holistic system provides consistent performance.  We are currently studying system dynamics in the context of:
  • Cluster & Grid Computing - the issues relating to systemic consistency focusing on network, scheduler, application, and environmental performance and management.
  • Advanced Data Transport Protocols - More efficient (possibly greedy) ways to move large data sets over distributed networks.
  • Sensor Networks - Sensor networks have allowed us to look at engineering and computer science challenges using a clean sheet of paper. We are investigating new ways to combine materials science, technology, and scientific applications in areas such as Bio-engineering, Hydrology, and Agriculture.
