Targeting CCM-, CEA-, and CSM-Based Computing to Specific Architectures Based upon HPCMP Systems Assessment

Each year the Department of Defense High Performance Computing Modernization Program (HPCMP) acquires new super computing hardware through a rigorous acquisition process, denoted "TI" for technology insertion, based primarily on application benchmarking. The corresponding suite of applications spans many disciplines and is carefully constructed to ensure that the HPCMP workload is accurately reflected. For the most recent acquisition cycle (TI-06), GAMESS, LAMMPS, OOCORE, and CTH7 were used to represent the computational chemistry and materials (CCM), computational electromagnetics and acoustics (CEA), and computational structural mechanics (CSM) computational technology areas (CTAs) in the workload, respectively. This paper will compare the performance of these four codes representing the CCM, CEA, and CSM components, respectively, of the TI-06 benchmarking suite on HPCMP systems to determine which system is best suited for each CTA
