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…

Simulating Turbulent Combustion Speeds Design of Power and Propulsion Devices

Supercomputers help optimize engines, turbines, and other technologies for clean energy High-fidelity large eddy simulation (LES) of direct-injection processes in internal-combustion engines provides an essential component for development of high-efficiency, low-emissions vehicles. Here LES reveals how fuel from a state-of-the-art injector mixes with air inside an engine cylinder. Image credit:…
