1．Outline of the system In addition to SORA-MA, JSS2 consists of advanced systems such as SORA-LM, a large-scale memory system, SORA-PP, a pre-post system, SORA-FS, a file system and J-SPACE an archiving system. JSS2 is also designed for energy saving by adoption of a water-cooling system. JSS2 is composed of these well-developed systems and eco-friendly policy. In April 2016, SORA-MA was updated to the peak performance 3.49 PFLOPS and the total memory size 100 TiB. Since then, JSS2 has been・・・<<read more>>
