A performance evaluation of CCS QCD Benchmark on the COMA (Intel(R) Xeon Phi$^{TM}$, KNC) system

Understand

The most computationally demanding part of Lattice QCD simulations is solving quark propagators.

• Quark propagators are typically obtained with a linear equation solver utilizing HPC machines.
• The CCS QCD Benchmark is a benchmark program solving the Wilson-Clover quark propagator, and is developed at the Center for Computational Sciences (CCS), University of Tsukuba.
• We optimized the benchmark program for a \Intel \XeonPhi (Knights Corner, KNC) system named "COMA (PACS-IX)" at CCS Tsukuba under the Intel Parallel Computing Center program.
