  1. Cristina Beldica DES-DM Project Manager NCSA -- University of Illinois at Urbana-Champaign Dark Energy Survey Collaboration MeetingData Management Status December 11, 2006 Chicago

  2. Outline • Progress to date • Funding for the DM component • Data Challenge Two • Goals and Schedule

  3. Schedule and Milestones • DM meeting: February 20, 2006 (Urbana) • DM Session at Collaboration meeting: May 18-20, 2006 (Barcelona) • DM meeting: last week of August, 2006 (Urbana) • DC2 begins (October 2, 2006) • Proposal to NSF – due December 20, 2066 • DC2 ends (January 31, 2007) • Review (February 2007)

  4. 2005 DES DM Proposal to NSF • DES DM 2005 proposal timeline • Submitted September 30, 2005 • May – June 2006 – encouraging news from NSF • June 30 – we were announced that the proposal won’t be funded • Main reasons cited: • NSF won't pay for its own telescope time – misreading of the MOU • why not take the computing to the data rather than taking the data to the computing • no firm DOE commitment • the need to see the entire project (DECam plus DM in one place) with description of full costs (including operations) and all sources of funding     

  5. Bridge Funding • New commitment from NCSA director – 1 FTE for 1 year (FY2007) • 50% of Dora Cai and Patrick Duda • New team member: Patrick Duda – middleware developer • Greg Daues officially off the DES DM team

  6. DES DM Participation to Conferences • The Future of Photometric, Spectrophotometric and Polarimetric Standardization, May 2006, Blankenberge (Belgium) • Main author: Douglas Tucker • SPIE Astronomical Telescopes and Instrumentation Conference, May 2006, Orlando, Florida • Main author: Choong Ngeow • AAS 208th Meeting, Jun 2006, Calgary, Alberta • Main author: Wayne Barkhouse • Canadian Astronomical Society Annual Meeting, Jun 2006, Calgary, Alberta • Main author: Wayne Barkhouse • TeraGrid ‘06 , "Advancing Scientific Discovery”, Jun 2006, Indianapolis • Main author: Greg Daues • ADASS 2006 Astronomical Data Analysis Software and Systems, Oct 2006,Tucson • Main author: Joe Mohr • SC2006, Nov 2006, Tampa • Greg Daues and Dora Cai • AAS 208th Meeting, Jan 2007, Seattle • Main author: Choong Ngeow

  7. Data Challenge 2 Overview • October 2, 2006 to January 31, 2007 • Next stage of development of the DES Data Management system • Build upon DC1 • integrated archive • catalog database • pipeline processing system • Plus • new components • higher levels of automation • quality assurance testing and fault flagging for pipeline stages • first attempt to meet the data quality requirements (SRD)
