The Durango Herald reports that final testing is being done on NCAR’s Yellowstone supercomputer on the outskirts of Cheyenne that will be used for climate modeling and other Earth sciences. At a cost of $30 Million, the IBM machine will be used to model air movement inside hurricanes and tornadoes and examine how weather and air quality could change in North America in the years ahead.

Yellowstone is a 1.5-petaflops IBM iDataPlex cluster computer with 4,518 dual-socket compute nodes that contains 9,036, 2.6-GHz Intel Xeon E5-2670 8-core processors (72,288 cores), and its aggregate memory size is 144.6 terabytes. The nodes interconnect in a full fat tree network via a Mellanox FDR InfiniBand switching fabric. System software includes the Red Hat Enterprise Linux operating system for Scientific Computing, LSF Batch Subsystem and Resource Manager, and IBM’s GPFS file system.

NCAR hopes to wrap up testing and accept the supercomputer in October. Read the Full Story.
