Vulcan is one of the largest, most capable computational resources available in the U.S. for industrial collaborators. This prodigious unclassified supercomputer is shared by the M&IC and ASC programs, with 1.5 of its 5 petaflops directly supporting NNSA’s mission to enhance U.S. economic competitiveness. Partners access Vulcan, whether for open, publishable science or business-sensitive and proprietary research, through the High Performance Computing Innovation Center.
HPCIC partners gain access to both a percentage of Vulcan for a period of time and to the entire associated infrastructure available in the world-class LC HPC environment, including subject-matter experts, network access, file systems, archive storage, and help-line support.
In addition to supporting HPCIC efforts, Vulcan is used for NNSA research programs, academic alliances, and LLNL institutional science and technology efforts.
The 24-rack IBM Blue Gene/Q system is based on the POWER architecture. Vulcan was part of the contract that brought Sequoia to Livermore.
