The simulations shown here were conducted on high performance computers at IMCS, and at super-computer centers around the world.

Rutgers IMCS Ocean Modeling Group uses super-computer facilities at:

The model of the North Atlantic Ocean, for example, has 250,000,000 unknown variables and takes 153 days to compute on 32 processors of an SGI Origin 3000 super-computer to obtain 7 years of simulation.
