GAEA is located in Oak Ridge, TN and operated by the National Climate-Computing Research Center (NCRC) The NCRC is a collaborative effort between the Department of Energy and the National Atmospheric and Oceanic Administration. It is located within the National Center for Computational Sciences (NCCS) in the Oak Ridge National Laboratory at ORNL’s National Center for Computational Sciences (NCCS).
The Gaea System consists of an HPE Cray XC40 supercomputer and an HPE Cray EX supercomputer. The XC40 system has 164 terabytes of memory and a peak calculating capacity of 3.52 petaflops. The EX system has 482 terabytes of memory and a peak calculating capacity of 10.2 petaflops.
In Q2FY24, the Gaea System will receive a new compute cluster, named C6. C6 will be an HPE Cray EX supercomputer with 584 TB of memory and a peak calculating capacity of 9.81 petaflops.
NOAA uses Gaea to study the earth's notoriously complex climate from a variety of angles. Gaea powers research into the relationship between climate change and extreme weather, such as hurricanes. Gaea enables scientists to better understand the relationship between the atmosphere’s chemical makeup and climate and assists to unlock the climate’s role played by the oceans that cover nearly three-quarters of the globe.
