US Researchers Refine Computer Modeling for Nuclear-Weapons Testing

Purdue University and Lawrence Livermore National Laboratory scientists are using supercomputers to refine the models that the US government uses to conduct critical nuclear-weapons performance simulations. The researchers are developing models that are accurate to the molecular level. These models would improve the accuracy of the highly complex simulations that are critical for the US to verify the performance of nuclear weapons without testing them via explosions. High precision levels are critical because many of the calculations are executed in parallel on separate machines in large clusters, which could turn small errors into large ones. The researchers also developed an automated tool that detects an error in the calculation process after it occurs so that they can correct it. They will present their work at the IEEE/IFIP International Conference on Dependable Systems and Networks in Boston. (EurekAlert)(Purdue University)
