DESCRIPTION:Graphs are at the core of many data processing problems\, whet
 her that is searching through billions of records for suspicious interacti
 ons\, ranking the importance of web pages based on their connectivity\, or
  identifying possible “missing” friends on a social network.   Using t
 hese workloads as examples\, I will describe challenges in building effici
 ent parallel implementations\, and the ways in which the operating system 
 is no longer providing effective abstractions of the underlying computer h
 ardware.  I will show how obtaining good performance and scalability requi
 res careful control over the placement of computation and storage within a
  system\, and an understanding of the structure of the data being processe
 d.  I will then talk about how I see the role of the operating system evol
 ving in distributed “rack scale” systems.\n
