What is a Core Hour on Titan?

For 2013 the Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program awarded 1.84 billion core hours on Titan, a hybrid-architecture high-performance computing (HPC) system that sports central processing units (CPUs) and graphics processing units (GPUs), which are radically different, in the same machine. So what exactly does…
