More Power, Please

The IBM Power 6 computer used by the National Weather Service to run its computer simulations of the atmosphere performs 17,100,000,000,000 calculations per second and it is not fast enough to run all of the models as quickly as we would like.

For example, the latest high resolution model used in extreme weather prediction (available here) is often an hour or two behind because we do not have enough computer power!
