Speakers: Richard Gerber, Jack Deslippe, and Doug Doerfler, National Energy Research Scientific Computing Center (NERSC)

NERSC is the production high-performance computing (HPC) center for the United States Department of Energy (DOE) Office of Science. The center supports over 6,000 users in 600 projects, using a variety of applications in materials science, chemistry, biology, astrophysics, high energy physics, climate science, fusion science, and more.

NERSC deployed the Cori system on over 9,000 Intel® Xeon Phi™ processors. This session describes the optimization strategy for porting codes that target traditional manycore architectures to the processors. We also discuss highlights and lessons learned from the optimization process on 20 applications associated with the NERSC Exascale Science Application Program (NESAP).
