"FEDERATION: Remote labs team up to simulate astronaut's heart"
Independent computer simulations running hundreds of miles apart have been harnessed to create a single, interacting supersimulation of the right and left ventricles of an astronaut's heart. The simulation tied together work done in separate labs, and represented the first successful U.S. application of an IEEE standard for organizing independent, distributed simulations into a larger, single simulation, called a federation.
