Building 453, the Terascale Simulation Facility, is a 253,000-gross-square-foot facility consisting of two computer clean rooms and a four-story office complex. The Terascale Simulation Facility design accommodates parallel processing computer systems of increasing computational power within the same footprint and building space. As computer systems change, old equipment would be removed and replaced with current, state-of-the-art equipment. The basic building structure, components, utilities, and exterior support facilities are designed to support the maximum planned computer load through 2014.

The Terascale Simulation Facility houses the 100-TeraOps-class (trillion operations per second) BlueGene/L computers and networks and the data and visualization capabilities necessary to perform the simulations essential to ensuring the safety and reliability of the U.S. nuclear stockpile. Using data from past test and surrogate experiments, computer scientists would conduct three-dimensional simulations of nuclear weapon performance. Space is available to support a weapons code development team to integrate experimental, physical, material, and computer sciences for support of stockpile stewardship requirements.
