9:00-10:00 AM - Keynote Lecture

• Google Flex.
  John Wilkes (Google, Inc.)
  
  Abstract: Ensuring that users in a computation cluster can receive strong guarantees about immediate resource availability is surprisingly hard to do without wasting significant amounts of resources. The Google Flex system gives administrators a way to define resource pools that provide a range of strong, statistically-backed guarantees based on user and job behavior, while also reducing human effort by automation tied into the Borg cluster manager, Colossus distributed file system, and many other services. Flex has been widely adopted at Google, and has produced significant resource savings.
  
  Biography: John Wilkes has been at Google since 2008, where he is working on automation for building warehouse scale computers. Before that, he spent a long time at HP Labs, becoming an HP and ACM Fellow in 2002. He is interested in far too many aspects of distributed systems, but a recurring theme has been technologies that allow systems to manage themselves.
