DASHMM Strong Scaling on Cori

A strong scaling test of the DASHMM library on the Cori supercomputer. The data plotted is the average of five repetitions of the evaluation times for three different kernels for two different source and target distributions. The left panel in the absolute time for the evaluation in second as a function of the number of nodes used (Cori has 32 core nodes). The right panel is the speedup relative to a single node of Cori. Shown in blue, yellow and red are the data for the Laplace, Yukawa and Helmholtz potentials, respectively. Lines with square markers used sources and targets distributed in a cube, and lines with circular markers are for runs that used sources and targets on the surface of a sphere.
