ORNL’s supercomputing program has grown from humble beginnings to deliver some of the most powerful systems in the world, including computing resources like Summit, an IBM AC922 supercomputer, Titan, a Cray XK7 supercomputer, and Eos, a Cray XC30 cluster.
The OLCF hosts data resources, like the HPSS archival file system and the Spider II center-wide parallel file system, and visualization tools, like the EVEREST analysis and visualization laboratory.
