Description

The 23,504-square-meter (253,000-square-foot) TSF at Lawrence Livermore National Laboratory houses the world's most powerful supercomputer—Sequoia. This amazing machine, which performs trillions of operations per second (teraFLOPS), supports the Advanced Simulation and Computing (ASC) Program, a part of the Department of Energy's National Nuclear Security Administration and an important component of stockpile stewardship. Supercomputers reside in the two computer rooms dominating the second level of the two-story supercomputer wing. A non-load-bearing wall separating the two rooms can be removed to create one large room should the need arise for more floor space for future ASC computers. Located on the ground floor beneath each computer room is a mechanical utility room. A total of 28 air-handling units blow cool air up to the second level, each at a rate of 80,000 cubic feet per minute. After cooling the computers, the air continues to rise upward and is forced into large return-air plenums for recirculation. TSF's four-story office tower provides research and development areas for visualization and hardware prototyping, a 150-seat auditorium and visualization theater for unclassified presentations, a second visualization theater for classified reviews, and an operations hub that controls the Computation Directorate's high-performance computers across the Livermore site. It also includes three small computer rooms to support facility infrastructure, an atrium-like lobby, conference rooms, and a classroom.
