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.

XtreemFS 是一个为互联网存储系统设计的分布式文件系统。-It allows you to mount an XtreemFS volume from anywhere, given the right permissions. It includes support for POSIX ACLs and extended attributes (xattrs). As an object-based parallel file system, it allows you to stripe files over multiple storage servers for high-performance parallel access with file-specific striping pattern. It can be integrated in X.509-based security infrastructures. When deployed as part of an XtreemOS Grid installation, you will benefit from its transparent integration with the XtreemOS Virtual Organization (VO) infrastructure in the form of dynamic user mappings and automatic mounting of home volumes。

ExpressionJ 是一个用来解析简单的算术表达式的 Java 类库。ExpressionJ is a Java library allowing to interpret simple numeric expressions, which may be used in all applications which have to combine numeric values, but do not want to use full-blown scripting languages.
