•Provide overview of NWSC

•Advertise some collaborative and EOT opportunities

•Advertise SiParCS Internship Program at NCAR

•Become more familiar with Utah research

Goals

The NCAR-Wyoming Supercomputing Center (NWSC) will provide the community

dedicated petascale capabilities.

The NWSC Facility is near Cheyenne, Wyoming

What it is: A new $70-million, 4.5 MW NSF supercomputing facility

What it does: Will house petascale supercomputers and data storage systems for Earth System science research

What it means: Greatly enhanced modeling capability for the community in climate and weather research

Status: Construction was completed in August, 2011. System install January 2012, operational mid 2012.

Earth System Science Drivers

• Clouds – a major source of error• Global Cloud Resolving Models• Super-parameterization scheme • Better Cloud Parameterizations

• Climate Change– Decadal Climate Prediction– Regional Climate Change Effects– Probability of Extreme Events

• Severe Weather – Hurricane Track and Intensity– Eyewall Precipitation and Winds– Probabilistic Forecasts

Supercomputing advances are allowing steadily improving fidelity with nature…

• Resolve ocean mesoscale eddies for climate studies

• Forecast Hurricanes with cloud resolving atmospheric processes

• Simulate solar flares faster than real time and resolve fine structure of corona’s B field• Understand sunspot activity Ocean component of CCSM

What’s in it for Utah?

Allocations: Wyoming controls 20% of NSF-base funded resources

Research Collaborations: The challenges and opportunities raised by the nexus of climate change & energy require the development of new collaborations

EOT: Internship opportunities, visitor programs, HPC training, atmospheric data analysis workshops, and more

Wyoming’s 20% Share of NWSC represents a huge increase in EPSCoR HPC

capabilities…• On the latest (6/11) Top500 list of fastest supercomputers,

Wyoming’s share on NWSC-1 alone is estimated to be…• Larger than TACC’s Lonestar system• The 28th fastest computer in the world on that list• The 14th largest supercomputer in the US on that list• The largest system in an EPSCoR state outside of Department of Energy

facilities on that list• The largest resource controlled by a university in the US on that list

• Of course, Moore’s Law will erode a bit over the next year, but still this will be a formidable capability when deployed!

Accessing NWSC Wyoming Allocations: Eligibility

Projects must:

• Have scientific merit as evidenced by federal funding, or separate review

• Be in an Earth System science area of substantial interest (e.g. hydrology; sequestration, atmospheric science, ecology, biosphere/atmosphere interactions, computational geofluid dynamics)

• Include UW researchers as principal or co-principal investigator

• Directly or through collaboration strengthen UW’s research capacity.

• Strengthen of computational science capacity in EPSCoR or regional states

Preference given to projects that

Accessing NWSC Wyoming Allocations
