China National Meteorological Agency at Merge 2013: Blue Skies Ahead

MERGE User Conference

Today, the national agency predicts storms, precipitation, pollution, ocean activity and more. Launched in 2001, the Global / Regional Assimilation and Prediction System (GRAPES) runs on heterogeneous high-performance computing clusters, modeling precipitation and other events throughout China. But as GRAPES expanded national coverage, versioning issues became apparent, says Zhao Chunyan, an engineer in high-performance computing at the National Meteorological Information Center in Beijing.

“In many cities in China, there is customized development of GRAPES for different research and forecasts. We have introduced Perforce for version management of the GRAPES model and are exploring the application in managing other climate model R&D,” says Chunyan, who will present the NMA’s approach to versioning at Merge 2013, The Perforce Conference in San Francisco.

“We use Perforce to manage numerical prediction models and climate models in R&D. This successful application of a distributed system is well adapted to the distribution of our research and development platform and team,” says Chunyan. To that end, Perforce’s branching and code line integration best practices are critical.

“System reliability is very important, so take full account of the performance of the system when planning. Use branching and integration to improve R&D efficiency,” Chunyan advises.
