NOAA Gets Cool New Computers

NOAA will be adding two new Cray computers (one operational and one backup) to replace existing hardware used in weather forecasting. According to a press release, “the computers — each with a 12 petaflop capacity — will be operational and ready to implement model upgrades by early 2022 after a period of code migration and testing. They will replace the existing Cray and Dell systems, “Luna” and “Mars” in Reston, Virginia, and “Surge” and “Venus” in Orlando, Florida.”

When combined with other hardware that will remain in use, the total capacity will rise to 40 petaflops. (A petaflop is a measure of computing speed equal to one thousand million million (1015) floating-point operations per second.) Given upgrades in storage and connectivity, and this increasing computing power, there will be a noticeable increase in resolution and other features of NOAA’s modeling of earth systems.

There is a rumor that the Trump Whitehouse plans to sell off the hardware to some friends who live out near the airport in Queens, and replace it with lower grade equipment that Trump claims works just as well (see illustration).

Though the press release does not give details, a spokesperson for NOAA just informed me that these computers will run the Linux operating system. I had assumed so, but wanted to check. Linux is the standard operating system for super computers, because it is a super operating system. Nobody wants to see the Blue Screen of Death in the middle of their tornado warning.

Specifically, the computers will run the Cray Shasta Linux Environment. This is a high performance suit designed to run large and complex applications on more than a half a million cores, with docker container support, and the robust Cray system management support including staged upgrading capabilities and the low overhead Cray system snapshot analyze.
