. It's some big iron: 1.1 petaflops, based on 16-core Interlagos chips from AMD, and built by Cray. "The system, which is used for climate modeling and resource, also includes two separate Lustre parallel file systems 'that handle data sets that rank among the world's largest,' ORNL said. 'NOAA research partners access the system remotely through speedy wide area connections. Two 10-gigabit (billion bit) lambdas, or optical waves, pass data to NOAA's national research network through peering points at Atlanta and Chicago.'"
