Sequoia ranked third in TOP500 list

NNSA’s Sequoia supercomputer, housed at Lawrence Livermore National Laboratory, is now listed as the third fastest supercomputer in the world according to the industry-standard Top500 list. 

Sequoia, which recently completed its transition to classified computing in support of NNSA’s Stockpile Stewardship Program, helps ensure the safety, security and effectiveness of the nation’s aging nuclear weapons stockpile without the use of underground testing. Sequoia was first delivered in 2011 and has achieved 17.17 petaflops on the Linpack benchmark using 1,572,864 cores. Sequoia is also one of the most energy efficient systems on the list, consuming a total of 7.84 MW and delivering 2,031.6 Mflops/W.

Vulcan made its first appearance on the Top500 list at No. 8. DOE and NNSA have four supercomputers in the first 10 of the Top500.

The Nevada Field Office (NFO) and its contract partner, the National Security Technologies (NSTec) Remote Sensing Laboratory (RSL) Aviation Department, have received the 2012 U.S. Department of Energy Jeff Snow Aviation Program Memorial Award. This is the fifth time in nine years that the NFO team has been recognized as the most outstanding DOE aviation program. Operating out of Nellis Air Force Base in Las Vegas and Joint Base Andrews, the NFO team provides aerial support to NNSA's Office of Emergency Response.

Les Winfield, NFO Aviation Manager, received the 2012 DOE Federal Aviation Management Professional Award. He is recognized for providing outstanding management and oversight of the NSTec RSL Aerial Measuring System operations at Nellis and Andrews. 

James Williams, Director of Maintenance for WSI-SRS Aviation Operations Department at the Savannah River Site, is the recipient of the 2012 John Cooley Aviation Operations/Support Professional Memorial Award. His outstanding management and leadership skills created a safe and efficient work environment, as well as ensured all maintenance technicians were well trained and knowledgeable in all aspects of the aircraft at Savannah River.

Tim Rourke, NFO Aviation Safety Officer, won the 2012 DOE Aviation Safety Professional Award. Rourke’s approach to safety and risk management of both ground and flight safety issues provided an objective assessment of program operational risks to NSTec senior managers. He recommended mitigation controls to reduce risks to the lowest practical level to permit aircrews to perform their critical national security mission.

The awards were announced by the DOE Office of Aviation Management -- each recipient will be honored at a ceremony in Alexandria, Va., on July 18.

Pantex recognized for outstanding community service

Civic organization Los Barrios de Amarillo honored B&W Pantex for its “Outstanding Community Service” this weekend. Los Barrios recognized B&W Pantex for its support of the “Step Up To Success” program, which connects young people with professionals in a variety of career fields that the students may want to pursue. Debra Halliday, community relations coordinator, accepted the award on behalf of the company. Halliday is joined in the photo by Los Barrios officials, from left, Historian Geo Cruz, Vice President Zeke Castro and President Sarena San Miguel.

At the recent ASM International Materials Camp, sixteen students got to check out almost a half-million dollars’ worth of lab equipment – including a precision cutoff saw, hot mounting press, specimen polisher, and scanning electron microscope. The week-long camp is hosted by Y-12, Oak Ridge National Laboratory, Tech 2020 and UT Knoxville, and is designed to expose students to materials science.

The participants learned how to prepare material samples for prosthetic implants, and then used a state-of-the-art optical microscope and digital imaging to identify signs of material failure. Y-12 engineer Steve Dekanich, who co-chairs the camp, remarked on the students’ ability to quickly master the advanced equipment.

The Aiken County Robotics Team “M’Aiken Magic” was recently revived after receiving $10,000 in donations from Savannah River Nuclear Solutions. The team comprises local middle school and high school students who work in groups to build robots capable of completing specified tasks. Competing in regional, state and world competitions, the students gain valuable experience as well as exposure to scientific and engineering concepts.

Last year, despite winning a world championship, the team lost almost half of its funding and multiple sponsors. SRNS President Dwayne Wilson explained that the donation, in addition to supporting local students, is an investment in the next generation of engineers, technicians and scientists.

The annual Laboratory Directed Research and Development program update was held this week in Washington, D.C. Experts from NNSA, Nevada National Security Site and Sandia, Lawrence Livermore and Los Alamos national laboratories attended and shared insights on successful projects and ongoing research. This year’s highlighted subject areas were Materials in Extremes, Big Data to Decisions, and Energy Use Impacts and Mitigation.

Keynote remarks were presented by:

Robert Meisner, Director, NNSA Laboratory Directed Research and Development/Site Directed Research and Development Programs
William Priedhorsky, LDRD Program Director at Los Alamos National Laboratory
Sheryl Martinez, LDRD Program Director at Sandia National Laboratories
William Craig, LDRD Program Director at Lawrence Livermore National Laboratory

The Director of National Intelligence recently recognized Department of Energy for its swift processing of security clearances. The Office of Personnel and Facility Clearances, part of NNSA’s Office of Defense Nuclear Security, handles the majority of DOE’s Q clearances and frequently exceeds established national timeliness goals for initiating and adjudicating them. In 90% of cases, OPFC adjudicates and grants initial security clearances in an average of 10 days once the completed security questionnaire is received, cutting in half the national requirement of 20 days.

OPFC cites several factors that contribute to its successful and timely support to the NNSA and DOE mission, including: utilizing six sigma methods to improve processes, formalizing standard operating procedures with ISO 9001 in mind, and developing a clearly defined strategic mission, vision and operational plan.

LLNL’s supercomputer Vulcan available for collaborative work

Lawrence Livermore National Laboratory’s Vulcan supercomputer is now available for collaborative work with industry and research universities. Operating at 5 petaflops (quadrillion floating point operations per second), Vulcan raises the amount of computing at LLNL available for external collaborations by an order of magnitude.

Named the world’s sixth fastest high performance computing system by the Top500 list in November 2012, Vulcan will allow large systems to be simulated over longer time periods with greater fidelity and resolution. It addition, it will contribute to work being done by scientists, engineers and computer scientists to solve high-impact problems across a broad range of scientific, technological and business fields.

Ron McIntosh, the Sandia National Laboratories/New Mexico (SNL/NM) Classification Officer, was recently awarded the Department of Energy’s Classification Award of Excellence for 2013.

McIntosh joined the SNL/NM Classification Office in 2002 and quickly demonstrated his vast knowledge of nuclear weapons classification. His excellent management and leadership skills led to his appointment as the Classification Officer for SNL/NM.  As a leader in the classification community, his innovative thinking brought numerous improvements to the classification process throughout NNSA and DOE.  McIntosh is an excellent example of the high quality of personnel within NNSA and continues set the bar high, as NNSA classification officials have received the award eight of the last ten years.
