“…the linear equation solver, while keeping the framework and measurement codes of Bridge++ available. This strategy was previously adopted to use GPUs with OpenCL and Ope-nACC [6,7]. We apply this extended-Bridge++ approach to KNL with modifications proper to the many-core and SIMD architecture.…”

We report the performance of Wilson and Domainwall Kernels on a new Intel Xeon Phi Knights Landing based machine named Oakforest-PACS, which is co-hosted by University of Tokyo and Tsukuba University and is currently fastest in Japan. This machine uses Intel Omni-Path for the internode network. We compare performance with several types of implementation including that makes use of the Grid library. The code is incorporated with the code set Bridge++.

“…The original fixed data layout with double precision floating point numbers is generalized to flexible data layouts in double or single precisions. Exploratory implementations and tuning have been studied for the SIMD architecture with Intel AVX-512 [5][6][7], GPU architectures with OpenACC [8,9] or OpenCL [10? ], the PEZY-SC manycore accelerator [11], and a vector architecture of NEC SX-Aurora TSUBASA [4]. In the framework of Bridge++ version 2, these machine-specific implementations are provided as alternative codes to the original implementation which takes over the specific tasks such as calculation of fermion propagators.…”

Bridge++ is a general-purpose code set for lattice QCD simulations aiming at a readable, extensible, and portable code while keeping practical high performance. The new version 2.0 employs machine-dependent optimization, enabling flexible data layout in float/double precision, while it was fixed layout and only with the double precision in previous versions. We report the performance on supercomputer Fugaku with Arm A64FX-SVE architecture by Fujitsu.
