Forecast Systems Laboratory Supercomputer Upgraded
Today's atmospheric researchers depend on supercomputers to develop high-resolution prediction models that more closely resemble the actual weather. FSL released the interim upgrade of their High Performance Computing System (HPCS) known as Jet to the user community on August 28, 2001. The interim upgrade added 280 additional Alpha CPUs to Jet. This brings the total number of computational CPUs in Jet to 560. Half of the CPUs are clocked at 667MHz while the new CPUs are clocked at 833MHz. The combined machine achieved 442 GigaFLOPS (billion arithmetic operations per second) on the standard LINPACK benchmark. The performance rating makes Jet the 56th most powerful computer in the world.
Jet provides computational capability for FSL modeling efforts, North American Atmospheric Observing System (NAOS) tests, high performance computing software development, and other NOAA entities. The latter include OAR/CDC, OAR/PMEL, OAR/ETL, OAR/AL, OAR/NSSL, NWS/NCEP, and several joint institutes.
Jet is a cluster of GNU/Linux computational nodes interconnected with a high performance network known as MyriNet. The interconnection speed is 1.28 billion bits per second (Gbs) on the older portion of Jet and 2 Gbs on the newer portion. This interconnection network makes it possible for Jet to function as a supercomputer.
