Description
<HTML>
Goals of the Open Science Grid Site Administrators Meeting
  • Figure out how to make OSG sites even better
  • Begin to build a community among the OSG sites
  • Share technical expertise
  • Have two-way discussions to hear concerns and share solutions

We will strive to have plenty of time built in to have discussions, not just talks. This is essential. Please come prepared to participate in the discussions, not just listen to people talking.

Meeting Rooms:
July 30, 2007: One West, located at ground floor of Wilson Hall (High Rise)
July 31, 2007: Curia II, located above the Wilson Hall cafeteria.

        Open Discussion: Storage in OSG
    • Lightning Talks One West, Wilson Hall

      One West, Wilson Hall

      Fermilab, Batavia, IL 60510

      We would like to have a forum for sites to share cool tips on how
      they built their site. How did you get NFS to scale across your
      1000 node cluster? How did you use splunk to find why your CE
      crashed at 11:53 every morning? Should everyone drop their batch
      system in preference for GNU queue? These topics may or may not
      be specific to OSG and grid computing, but do apply to common
      problems that sites might have.

      There just isn't time for all of these wonderful talks. If we
      have at least 4 people interested, we'll have a session on Monday
      for lightning talks.

      Lighting talks will be limited to five minutes, including Q&A. NO
      LONGER. If you have PowerPoint slides, they must be preloaded
      onto a computer we will provide.

      The goal of a lightning talk is two-fold:
      - Make a point that can stick in someone's head
      - Generate discussions that can be held later (dinner, breaks,
      open
      sessions, etc.)

      If we have sufficient interest from people wanting to give a
      lightning talk, we'll re-arrange the schedule to do them. Let us
      know if you're interested.
