Metrics of Success
  • Project goals?
  • Papers published?
  • Technology transfer?
  • Adoption of approach in the real world?
  • Students produced?
  • Marriages?
  • Research results?
  • Unexpected research results?
  • All of the above?

Project Goals
  • Fundamental change in how we design large-scale
    computing systems
  • snap together commodity components
  • self-managing, self-tuning, highly available
  • Make the killer network real
  • realize the potential of emerging hardware
    technology
  • and push its effect through the rest of the
    system
  • Integrated system on a building-wide scale
  • pool of resources (proc, disk mem)
  • remote processor and memory closer than local
    disk
  • federation of systems with local and global role
  • The right way to build internet services
