文件输出或检查点的中间结果经常出现在适当的时间间隔，在大规模的时间推进数值模拟，它们被用于模拟后处理和/或重新启动连续的模拟。然而，由于处理器和/或辅助存储系统（如硬盘驱动器（HDD）和固态驱动器（SSD））之间的带宽限制，用于大规模数据的文件输入/输出（I/O）通常花费过多的时间。因此，正在努力减少文件I/O操作所需的时间，以便加速这种模拟，这意味着有必要获得与所使用的高性能计算系统相关的高级I/O性能知识。在这项研究中，I/O性能相对于矢量主机（VH）服务器和矢量引擎（VE）之间的连接带宽的SX-Aurora TSUB-ASA超级计算机系统的三种配置，特别是A300-2，A300-4和A300-8配置，进行了测量和评估。加速I/O功能是SX-Aurora TSUBASA I/O系统的一个显著特征，与其正常I/O功能相比，该功能具有出色的性能。
File outputs or checkpoints for intermediate results frequently appear at appropriate time intervals in large-scale time-advancement numerical simulations where they are utilized for simulation post-processing and/or for restarting consecutive simulations. However, file input/output (I/O) for large-scale data often takes excessive time due to bandwidth limitations between processors and/or secondary storage systems like hard disk drives (HDDs) and solid state drives (SSDs). Accordingly, efforts are ongoing to reduce the time required for file I/O operations in order to speed up such simulations, which means it is necessary to acquire advanced I/O performance knowledge related to high-performance computing systems used. In this study, I/O performance with respect to the connection bandwidth between the vector host (VH) server and the vector engines (VEs) for three configurations of the SX-Aurora TSUB-ASA supercomputer system, specifically the A300-2, A300-4, and A300-8 configurations, were measured and evaluated. The accelerated I/O function, which is a distinctive feature of the SX-Aurora TSUBASA I/O system, was demonstrated to have excellent performance compared to its normal I/O function.
