Simulations Show Nuclear Weapon Performance In Molecular Detail
2012-06-06 03:56:29

U.S. researchers are perfecting simulations that show a nuclear weapon's performance in precise molecular detail, tools that are becoming critical for national defense because international treaties forbid the detonation of nuclear test weapons. The simulations must be operated on supercomputers containing thousands of processors, but doing so has posed reliability and accuracy problems, said Saurabh Bagchi, an associate professor in Purdue University's School of Electrical and Computer...

Purdue University researchers, working with high-performance computing experts at Lawrence Livermore National Laboratory, have created an automated program to "debug" simulations used to more efficiently certify the nation's nuclear weapons. The program, called AutomaDeD (pronounced like automated), finds errors in computer code for complex "parallel" programs. "The simulations take several weeks to run, and then they have to be debugged to correct errors in the code," said Saurabh Bagchi, an...
