SC ’97 Inter-Continental Online Visualization and Control of T3E Simulations of Black-Hole-Interactions and Gravitational Waves Researchers at the Max-Planck-Institut für Gravitationsphysik and Rechenzentrum Garching der Max-Planck-Gesellschaft are collaborating with scientists at the National Center for Supercomputing Applications and Argonne National Laboratory to solve the 3D Einstein equations to simulate interactions between black holes and gravitational waves in support of design and interpretation of detection experiments. Gravitational wave iso-surfaces can be selected and displayed near to realtime with the ImmersaDesk equipment. Configuration An 8,000-mile-long intercontinental network connection provided by: RZG (Garching, Germany) - (B-WiN, DFN) - RUS (Stuttgart) - (public ATM, DTAG) - (CANTAT-3, Teleglobe) - (CA*netII, CANARIE INC / NTN) - STAR TAP / Chicago - (vBNS, NSF) - Argonne - (ATM-OC3, ANL) - San Jose.  Special TCP / IP tuning for efficient long distance transfers has been implemented in the communicating applications in Garching and San Jose.
