LLNL is home to Sequoia, ranked No. 2 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
- 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.
- Tips and usage notes for CZ and RZ access
- Computing resource management information
- Scratch and temporary (tmp) file systems are subject to purge. See the File Purge Policy and save important files to another location or archive needed files to storage.
- Possible purge of the Lustre parallel file systems. See Technical Bulletin 411.
- Tri-Lab High Performance Computing support
