Tour of LLNL Building 453 the Data Livermore Computing Complex (LCC)


The tour will be of LCC B453 building, the world-class computing facility at LLNL. This facility was designed for multiple generations of supercomputers and includes a four story office tower and 48,000 square feet of unobstructed computer room floor. The cooling system capacity 7,200 tons and air handlers with a capacity 2,720,000 cubic feet per minute that can cool 9.6 megawatts. The building will be home to the next-generation advanced technology system being procured to be delivered in early 4th quarter of 2017 - this machine will be called the Sierra.

Livermore computing facilities include both the necessary physical facilities and the operational support for reliable, cross-lab production of computing and storage. Also, included is the suite of user services needed for effective use of tri-lab computing resources with Los Alamos and Sandia National Laboratories.

Anna Maria Bailey


Anna Maria Bailey is LLNL's high performance computing (HPC) Facilities Operations Manager and is the co-chair of the Energy Efficient HPC Working Group (EEHPCWG). Anna Maria holds a B.S. in Electrical Engineering from Cal Poly, San Luis Obispo and is registered with the California Board for Professional Engineers and Land Surveyors as an electrical engineer. She has nearly 30 years experience in multiple engineering roles at Lawrence Livemore, notably serving as the design and construction manager of LLNL's HPC Center, which houses some of the world's most powerful supercomputers. In addition, Anna Maria led the effort to earn LEED certification for two LLNL HPC facilities and is currently just completed overseeing the construction of a new unclassified HPC facility. As the co-lead of the EEHPCWG, she sets the vision to encourage implementation of energy conservation measures and energy efficient design in high performance computing (HPC).

Mark Gary


Mark Gary is a Deputy Division Leader for the Livermore Computing Division within Computations. In this role Mark has responsibilities for the 24X7 operation of LLNL's world-class computing environment. Livermore Computing provides reliable high performance computers, infrastructure and services (networks, data archive, operations, file systems, system software, visualization, system administration, user assistance, and consultation) in support of LLNL missions. Mark leads projects ranging from leading integrated LC planning efforts, to external collaborations in support of extreme scale computing and storage futures.

Mark has worked on all aspects of High Performance Computing (HPC) at Livermore over the last 32 years. While the primary focus of his work has been on mass storage and parable file systems, Mark has also worked on operating systems, driver and kernel development. He is a co-author of HPSS and UniTree archival storage systems. Mark has co-managed successful government/industry collaborations over the last three decades and has led archival storage and Lustre file system development and operations teams.

Mark received his BS in Computer Science from the University of California, Santa Barbara in 1984.
