摘要：

RIKEN and Fujitsu have been developing the world's fastest supercomputer, the K computer. In addition to over 80 000 compute nodes, the K computer has several tens of petabytes storage capacity and over one terabyte per second of I/O bandwidth. It is the largest and fastest storage system in the world. In order to take advantage of this huge storage system and achieve high scalability and high stability, we developed the Fujitsu Exabyte File System (FEFS), a clustered distributed file system. This paper outlines the K computer's file system and introduces measures taken in FEFS to address key issues in a large-scale system.
