The National Center for Atmospheric Research (NCAR) has commenced operations of the new Cheyenne supercomputer, one of the world's most powerful and energy-efficient systems.
Three times more energy efficient than its Yellowstone predecessor, the 5.34-petaflop supercomputer has a peak computation rate of more than 3 billion calculations per second for every watt of energy consumed. The new centralized file system transfers data at a rate of 220 Gbps, more than twice as fast as the previous file system.
Housed in the NCAR-Wyoming Supercomputing Center, Cheyenne is ranked as the fastest supercomputer in the Mountain West region, and 20th fastest in the world.
Cheyenne will be used to study atmospheric and Earth sciences phenomena, such as weather, space weather, renewable energy, and natural disasters. Future applications for Cheyenne will include several studies in long-range weather forecasting, projections of electricity output at wind farms, and climate engineering simulations.
