  3. 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?

  4. 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

  6. Adoption of the Approach

  7. NOW publications • Over 40 papers and counting • wide range of important venues • IEEE Micro, ACM TOCS, ISCA, ASPLOS, SOSP, SIGMETRICS, OSDI, SIGMOD, SPAA, SC, IPPS/SPDP, JSPP, USENIX, Hot Interconnects, SW Prac. and Exp., SPDT, HPCA, … • countless presentations

  8. NOW Students • Moved on • Mike Dahlin (UT), Steve Rodriguez (NetApp), Steve Luna (HP), Lok Tin Liu (Intel), Cedric Krumbein (Microsoft) • Moving on • Doug Ghormley (Sandia), Randy Wang (Princeton), Amin Vahdat (Duke), Andrea Arpaci-Dusseau (Stanford), Steve Lumetta (UIUC), Rich Martin (Rutgers) • Finishing • Remzi Arpaci-Dusseau, Satoshi Asami, Alan Mainwaring, Jeanna Neefe Mathews, Drew Roselli, Nisha Talagala • On to other projects in CS • Brent Chun, Kim Keeton, Chad Yoshikawa, Fred Wong • and several undergrads • Josh Coates, Alec Woo, Eric Schein, ...
