|LLNL is home to Sequoia, ranked No. 3
TOP500 list of world's most powerful supercomputers.
Livermore Computing Center (LC) is home to a first-class computational infrastructure that supports the computing requirements of the Laboratory's research scientists. A particular focus of the Center is to develop solutions (in collaboration with tri-lab partners at Los Alamos and Sandia National Laboratories) that will create a functional problem-solving environment for high performance computers under the Advanced Simulation and Computing (ASC) program. Another goal is to provide leveraged, cost-effective high performance computing to multiple programs and independent researchers under the Multiprogrammatic and Institutional Computing (M&IC) program.
