Lawrence Livermore National Laboratory

ASC facilities include both the necessary physical facilities and the operational support for reliable, cross-lab production computing and storage environments. Also included is the suite of user services needed for effective use of ASC tri-lab computing resources. The scope of facility operations at LLNL includes planning, integration and deployment, continuing product support, software license and maintenance fees, procurement of operational equipment and media, quality and reliability activities, and collaborations. Facility support covers physical space, power and other utility infrastructure, and local area network (LAN)/wide area network (WAN) networking for local and remote access, as well as requisite system administration, cyber-security, and operations services for ongoing support and addressing system issues.

Building 654 in the Livermore Computing Complex

Sited at Lawrence Livermore National Laboratory (LLNL), a new, dual-level modular facility—Building 654—was dedicated in June 2016, and now houses platforms acquired as part of the commodity technology systems (CTS-1) procurement announced in October 2015. The approximately $10M-building consists of a 6,000-square foot machine floor flanked by support space. The main computer structure is flexible in design to allow for possible expansion and to accommodate future computer technology advances in high performance computing (HPC). In fiscal year 2018, LLNL intends to add to B654 a powerful but smaller companion platform modeled off of the "Sierra" advanced technology system.

B654 provides unclassified HPC system space suitable for supporting the National Nuclear Security Administration's (NNSA's) Advanced Simulation and Computing (ASC) Program, other related national security missions, and collaborations with academia. ASC is the simulation effort for NNSA's stockpile stewardship program to ensure the safety, security and effectiveness of the nation's nuclear deterrent without additional underground testing.

Building 453 in the Livermore Computing Complex

LLNL's world-class computing facility, LCC B453, was designed for multiple generations of supercomputers. The modern structure includes:

  • A four-story office tower, with 121,600 square feet for 285 offices, a visualization theater, a 150-seat auditorium, and several conference rooms.
  • A machine floor, with 48,000 square feet of unobstructed computer room floor, 30 megawatts machine power capacity, and 7,200 tons of air conditioning capacity.
  • A mechanical cooling system, with cooling towers boasting total capacity of 12,600 gallons per minute, a chiller plant with total capacity of 7,200 tons, air handlers with a total capacity of 2,720,000 cubic feet per minute, and a 3,600-gallon-per-minute, closed-loop, liquid-cooling system for Sequoia that can cool up to 9.6 megawatts.

LCC B453 was previously known as the Terascale Simulation Facility (TSF), a name that was outgrown when the ASC Program achieved petascale computing. The building will be home to the next-generation advanced technology system being procured through CORAL.

In 2010, LCC B453 received a Leadership in Energy and Environmental Design (LEED) gold level certification under the U.S. Green Building Council (USGBC) rating system. LEED is an internationally recognized green building certification system that provides third-party verification that a building or community was designed and built using strategies aimed at improving performance in energy savings, water efficiency, carbon dioxide emissions reduction as well as other factors.

Built by M. A. Mortenson Construction Company of Minneapolis, Minnesota, LCC B453 was completed in late 2004, ahead of schedule and within budget. Photos and text documenting the pre-construction site view and artist's renderings, the groundbreaking, month-by-month construction progress, and the ribbon-cutting ceremony are available in the TSF Construction Scrapbook.
