Vulcan is the first of four computers in the top 10 running on IBM's powerful BlueGene/Q platform with Power BQC 16-core 1.6GHz processors. Besting the previous entry by over a petaflop, this powerhouse performs at 4.3 petaflops with its nearly 400,000 cores.

This supercomputer is one of two in the top 10 operating at the U.S. Department of Energy's National Nuclear Security Administration (NNSA) at the Livermore National Laboratory (LLNL) in California. In mid-2013, the lab opened up computer time on Vulcan to U.S. businesses for collaborative work on projects that will increase scientific and technological advancement, improve U.S. competitiveness and enhance the high-performance computing (HPC) workforce, all in exchange for a share of the operational costs. Vulcan is also intended for collaboration with academic and research institutions in areas such as energy, security, atmospheric science and bioscience.
