  1. NCEP Central Operations Capabilities Brent Gordon NCEP/NCO/Systems Integration Branch NextGen System of Systems Workshop October 7, 2009 “Where America’s Climate, Weather, Ocean, and Space Prediction Services Begin”

  2. NCO Mission • Execute the NCEP operational model suite • Create climate, weather, ocean and environmental hazard products • Manage improvements to the NCEP model suite and supporting infrastructure • Model enhancements, other infrastructure • Develop meteorological software • Used by the NCEP Centers to create forecaster generated products • Manage the flow of data and products • To and from the NCEP centers, partners, and customers • We pride ourselves in delivering the goods on time and all of the time

  3. NCEP Operational Model Suite • NCO executes a world-class suite of operational models • 20 model runs per day • 4 to 24 different cycles per day • Models span a wide spectrum, including: • Seasonal • Global • Ocean • Regional • Hurricane • Hazard

  4. OCCS Capability Two Identical IBM Power6 Systems • 69.7 Teraflops Linpack • #36 Top 500 Nov 2008 • 156 Power6 32-way Nodes • 4,992 processors @ 4.7GHz • 19,712 gigabytes memory • 170 terabytes of disk space • 100 terabyte tape archive Gaithersburg, Maryland Fairmont, West Virginia

  5. Network Diagram

  6. NCEP Compute Farm • Compute capacity available outside of OCCS • Runs smaller scale applications than OCCS • 30 Blade system – Running VMWare • 8 cores (processors) per blade • 32 GB Ram per blade (960 GB total) • 36 TB total Disk Space • Currently at NCEP WWB • Will move to the NCWCP in College Park • A offsite back-up is being developed in Fairmont, WV at this time

  7. Supported Standards/Formats • NCEP adheres to WMO standards • GRIB, BUFR, CREX formats are primary • NetCDF is supported as well • Limited support • NCO concern about lack of standards • Fortran is predominant language on CCS • However C, C++, Java, Python are all used and supported by NCO • We can support just about any standard • Must have a strong, solid business case • Must have continued backing of the development organization

  8. Road to Operations • Solid CONOPS and Test plans are a must • Applications using NCEP model data as primary input should be developed with the NCEP OCCS architecture in mind • Numerous standalone systems not a good business model • Must preserve our 99.9% on time delivery rate • Applications must be robust and failsafe • Proper documentation a requirement
