  1. Climate Modeling Using computers to do the most impossible math homework known to man

  2. What goes into a Model? http://www.windows2universe.org/earth/climate/images/gcm_model_grid_hi_res.mov

  3. Supercomputer Specs • Bluefire • Houses the POWER6 microprocessor • clock speed of 4.7 gigahertz. • System consists of 4,064 processors, 12 terabytes of memory, and 150 terabytes of FAStT DS4800 disk storage • Peak speed of more than 76 teraflops (76 trillion floating-point operations per second) • Bluefire consists of 11 cabinets weighing 3,200 pounds each.

  4. How Long does it take? • Weather models are done daily, but are for very short time frames • Only “accurate” for 2-4 days • Climate Models can take months to a year • Dependant upon resolution desired • Dependant upon number of variables If a person would try to do all of the calculations for even a simple model, it would take them thousands of lifetimes!
