To calculate the movements of a mere 600 atoms in an explosion-produced mixture of
hydrogen fluoride and water vapor for 1 trillionth of a second, scientists have
had to tie up the most powerful supercomputer available for about 15 days. With

that can perform the task much more quickly.
Housed at the Lawrence Livermore (Calif.) National Laboratory (LLNL), ASCI White
is a product of the National Nuclear Security Administration's Accelerated
Strategic Computing Initiative (ASCI). The initiative is part of an effort to
