The Joint Center for Advanced High Performance Computing (JCAHPC) announced that the storage performance of the Oakforest-PACS supercomputer has ranked #1 in the first IO-500 list released in November 2017. The IO-500 is a world ranking list of storage performance, which is evaluated by the IO-500 benchmark that measures the storage performance using read/write bandwidth for large files and read/write/listing performance for small files. Storage performance in supercomputers is critical for large-scale simulation, big data analysis, and artificial intelligence. The IO-500 list facilitates to improve the storage performance that greatly helps to improve the CPU performance.
