Scaling tests of a new algorithm for DFT hybrid-functional calculations on Trinity Haswell

Wright, Alan F.; Modine, N.A.

We show scaling results for materials of interest in Sandia Radiation-Effects and High-Energy-Density-Physics Mission Areas. Each timing is from a self-consistent calculation for bulk material. Two timings are given: (1) walltime for the construction of the CR exchange operator (Exchange-Operator) and (2) walltime for everything else (non-Exchange-Operator).
