msnbc.com: Supercomputing has helped astrophysicists create massive models of the universe, but such simulations remain out of reach for many in the US and around the world.To compensate, groups around the world—such as the University of Chicago and CERN in Switzerland—are developing ways in which different research groups can contribute and see the results of supercomputer simulations in real-time by streaming the results over the internet.One of the first tests of such a system occurred last week in which scientists in Portland, Oregon, watched a Chicago-based simulation of how ordinary matter and mysterious dark matter evolved in the early universe.
