Lukas Spies works within XPACC under the supervision of Dr. Luke Olson. His main focus is on using large heterogeneous systems for BLAS-1 type computations, and how such systems can be used to increase the performance of PlasComCM. In addition, he also works on general halo exchanges between CPUs and GPUs. He holds a B.S. in Mathematical Science from the National University of Ireland, Galway, and a M.S. in Scientific Computing from Memorial University of Newfoundland, Canada.
