Gaea is comprised of two Cray XC40 systems. The aggregate Gaea system contains more than 200 terabytes of memory and a peak calculating capability greater than 5.25 petaflops (quadrillion floating point operations per second).
A high-capacity parallel filesystem provides over 32 petabytes fast access storage. The center-wide filesystem is connected using FDR InfiniBand to the center’s compute and data-transfer resources.
NOAA research partners access data remotely through speedy interconnections. Two 10-gigabit (billion bit) lambdas, or optical waves, pass data to NOAA’s national research network through peering points at Atlanta and Chicago.
