ABSTRACT
The role of high end computing in climate simulation is well
established by over three decades of experience. As we move toward
petascale computing there will be continued emphasis on climate model
development and international collaboration in the scientific study of
climate. Among the challenges for the development of next generation
climate models are the complexity of coupling multi-scale processes and
dynamic component models in a simulation that encompasses several
centuries. Algorithmic advances in the calculation of atmospheric and
oceanic flows must be incorporated along with parallel decompositions
that allow scaling to tens of thousands of processors. Current climate
models include atmosphere, ocean, land and sea ice components and
effectively utilize hundreds of processors. New capabilities to couple
tropospheric chemistry, dynamic vegetation and ocean ecosystems with
full carbon and chemical feedbacks are now being developed. The path
for integration of these diverse components into a common simulation
framework, such as the Community Climate System Model, while still
improving the fundamental physical representations of climate in the
model, will be discussed. Computational performance and a sampling of
IPCC simulation results will be presented.
