Gfarm 是一个分布式的文件系统，主要用于大规模的集群计算。It’s implemented in userland, and can be mounted by FUSE. It utilizes locality of a file to access a data node, and supports Globus GSI for Wide Area Network. Users can control file replica location on Gfarm. Gfarm can be used as an alternative storage system to HDFS for Hadoop, Samba, and GridFTP.
