At #1 on the TOP500, the 17.59 Petaflop Titan supercomputer at Oak Ridge is a hybrid system powered by 299,008 AMD Opteron cores and 18,688 Tesla K20X GPUs. ORNL uses Adaptive Computing’s Moab HPC Suite and TORQUE to prioritize jobs, and Moab gives them the flexibility to schedule jobs based on a variety of criteria, including user, project and resource utilization.
As an important resource of the Department of Energy, we are focused on answering the most pressing questions in science today,” noted Don Maxwell, HPC systems team lead at Oak Ridge National Laboratory. “Keeping our utilization high is important as we produce results, and Adaptive Computing’s Moab technology gives us tremendous flexibility in allocating our resources according to our priorities.”
On the Green500 side, the Beacon System at the National Institute for Computational Sciences at the University of Tennessee was able to achieve a peak performance of 112,200 gigaflops while using just 44.89 kW of power.
One of the hallmarks of being green is keeping energy consumption at a minimum while maintaining performance,” said Troy Baer, Senior HPC System Administrator at the National Institute for Computational Sciences, University of Tennessee. “That means we need flexibility in scheduling, which makes Adaptive Computing’s Moab technology an indispensible tool for us.”
