Application #1. Updated scaling study on ORNL Cray XK7 system
Recent scaling results out to 80,000 cores on the Cray XK7 system at Oak Ridge National Lab. Several grid sizes shown, with grid element counts in parenthesis. Largest case is a grid based on one of the wing-body geometries from the 3rd AIAA Drag Prediction Workshop, containing 918 million nodes and 5.5 billion elements. Scaling is reasonable despite only ~11,000 degrees of freedom per core at the high end. Future runs will use larger meshes providing more work per core to hopefully scale further.
