Federal Office of Meteorology and Climatology - MeteoSwiss

CSCS carries out the simulations for the daily forecast of the Swiss national weather service MeteoSwiss. In May 2007, a Cray XT4 system for the new high-resolution forecast suite of MeteoSwiss was installed at CSCS. The model uses a grid of 2.2 km resolution and is operated in addition to the standard long-forecasting model with a 7 km spacing. The high-resolution model is run 8 times a day on a machine with 880 AMD Opteron cores at 2.6 GHz, which reaches a peak performance of 9.2 Tflops.
