Gaea

Gaea is comprised of two HPE-Cray EX 3000 systems. The aggregate Gaea system contains a peak calculating capability greater than 20 petaflops (quadrillion floating point operations per second).

Two high-capacity parallel filesystems provides over 150 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.
