| 概要 | This project focuses on porting CPU-based applications to accelerator-equipped supercomputers and developing efficient methodologies for this transition. Targeting the upcoming Miyabi-G supercomputer, equipped with NVIDIA GH200, the project aims to optimize the seismic wave simulation code OpenSWPC and other applications using standard methods, ensuring ease of use for non-HPC researchers. Key objectives include evaluating Kokkos, a performance portability library, against OpenMP, OpenACC, and SYCL, and exploring its use for both C++ and Fortran applications. By utilizing GH200’s tightly coupled GPU-CPU architecture, the project aims to enhance communication, IO, and overall application performance while maintaining productivity and portability. |
