1. NCAR Supercomputing ‘Data Center’ Project An NCAR-led computing ‘facility’ for the study of the Earth system May 30, 2006

2. Project Review NCAR Mesa Lab computer facility: power, cooling and floor space will be inadequate beyond the current procurement Science being restricted by focusing on capacity ahead of capability Facility concept: 30,000 (initial to 60,000) sq. ft., 150,000 (to 300,000) sq. ft., 4 (to 24) MW redundant power, cooling, ~ 20 year lifetime Phase 1 facility est. construction cost @ $50M to $70M –Such a facility would be a computational equivalent of the Hubble Telescope for geoscience simulation

6. Schedule Project plan development - Sep-Dec Community engagement - Ongoing Partnership development - Nov-Mar, down-select in April and June Engage National Science Foundation (GEO, OCI) - Ongoing Forge international collaborations (UK/NERC, ENES) Initiate facility building project ~ Summer 2006 Community workshop - September at NCAR Submit project prospectus to NSF – Jan 2007 First electrons ~ Summer 2010 20062007200820092010 Discovery Planning/Financing Design Construction

7. An Opportunity NSF’s Petascale Roadmap “Overarching Recommendation: Establish a Petascale Collaboratory for the Geosciences with the mission to provide leadership-class computational resources that will make it possible to address, and minimize the time to solution of, the most challenging problems facing the geosciences.” www.joss.ucar.edu/joss_psg/meetings/petascale/

8. NSF’s Cyberinfrastructure Vision 2006-2010 A petascale center linked with multiple 100+ teraflop centers… Track-1 $200m 1 Petaflop Sustained Track-2 $30m 100TF Track-2 $30m
