Climate Modeling: How much computing required to run a Century Experiment?
By Josh Simons on Nov 18, 2009
Henry Tufo from NCAR and CU-Boulder spoke this weekend at the Sun HPC Consortium meeting here in Portland, OR. As part of his talk, More than a Big Machine: Why We Need Multiple Breakthroughs to Tackle Cloud Resolving Climate [PDF], he estimated the number of floating-point operations (FLOPs) needed to compute a climate model over a one-century time scale with a 1 km atmosphere model.
His answer was the highlight of the Consortium for me: A Century Experiment requires about a mole of FLOPs.
