SGI Detail

This page shows detailed results submitted across a number of systems and options (detailed below) submitted with the SGI benchmark results.  Scroll down past plots for additional information.

 

12 KM CONUS Benchmark

The domain is 12 KM horizontal resolution on a 425 by 300 grid with 35 vertical levels, with a time step of 72 seconds.  The benchmark is restarted on October 25, 2001 00Z and run for 3 hours and then the time per timestep is averaged over all but the first time step, which is discarded.  The average time per time step is divided by the operation count for an average time step, 30.1 billion floating point operations[1], to determine floating point rate.  Return to the WRF V3 Benchmarks Page for additional information.
