University of Delaware National Center for Atmospheric Research (NCAR) scientists have received a $1,064,500 grant from the U.S. National Science Foundation to conduct research on multiscale modeling of turbulent clouds through petascale computing. The simulations proposed by the researchers are extremely computation-intensive, and the group will re-design and optimize their simulation codes to explore multi-level parallelism on next-generation heterogeneous supercomputers.

"Since petascale computing is on the horizon, our hybrid approach can be realized and fully explored to address open questions that have challenged atmospheric scientists for years," says Delaware professor Lian-Ping Wang. "We will develop cloud microphysics parameterization for coarser resolution computational models. This will benefit weather and climate modeling from short-term, storm-scale forecasts to longer-term climate change."

Researchers Guang R. Gao and Xiaoming Li will use NCAR's parallel computers to study the various computing challenges, such as scalability and performance portability, encountered when creating large-scale and complex scientific simulations. Delaware professor Chandra Kambhamettu will develop interactive visualization tools to help in the management of the massive amount of data the project will develop.
