LLNL is home to Sequoia, ranked No. 3 on the
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.

Announcements

LLNL Collaborators. The processes for managing the accounts of LLNL Collaborators have been revised. All LLNL Collaborators and their sponsors should review the changes to computing access for Collaborators.
Using the Sequoia BG/Q System. This online tutorial provides guidance for using LC's Sequoia, Vulcan, and RZuSeq systems. Additional BG/Q documentation is available on LC's internal wiki at https://lc.llnl.gov/confluence and in /usr/local/docs on all BG/Q systems.

Reminders

Access to LC machines requires a one-time password (OTP) token + PIN from an LLNL-issued RSA token and an LLNL-issued OTP CRYPTOCard for Restricted Zone (RZ) access. If you do not possess an LLNL-issued RSA token or are an RZ user and need an LLNL-issued CRYPTOCard, please contact the Hotline.
