Vulcan is a 24-rack supercomputer system that was created by IBM for the DoE and is stationed at the Lawrence Livermore National Laboratory in Livermore, California. It has a 5 PetaFLOPS peak, and is currently the ninth fastest supercomputer in the world, according to Top500.org. The BlueGene/Q is the third generation of IBM projects (after BlueGene/L and BlueGene/P) that aims at creating supercomputers that can reach operating speeds in the PFLOPS range, with low power consumption.
Vulcan became usable in 2013, and Lawrence Livermore National Laboratory for research in biology, plasma physics, climate science, molecular systems, solid and fluid engineering, and other complex subjects of study. It is also used in support of DoE and National Nuclear Security Administration (NNSA) missions.
