It is ideal +for large storage problems faced by HPC, BigData, Streaming Video, +Genomics, Bioinformatics. + +Orangefs, originally called PVFS, was first developed in 1993 by +Walt Ligon and Eric Blumer as a parallel file system for Parallel +Virtual Machine (PVM) as part of a NASA grant to study the I/O patterns +of parallel programs. + +Orangefs features include: + + * Distributes file data among multiple file servers + * Supports simultaneous access by multiple clients + * Stores file data and metadata on servers using local file system + and access methods + * Userspace implementation is easy to install and maintain + * Direct MPI support + * Stateless + + +MAILING LIST +============ + +http://beowulf-underground.org/mailman/listinfo/pvfs2-users + + +DOCUMENTATION +============= + +http://www.orangefs.org/documentation/ + + +USERSPACE FILESYSTEM SOURCE +=========================== + +http://www.orangefs.org/downloads/LATEST/source/orangefs-2.9.0.tar.gz + +Orangefs versions prior to 2.9 would not be compatible with the +upstream version of the kernel client. + + +BUILDING THE USERSPACE FILESYSTEM ON A SINGLE SERVER +==================================================== + +When Orangefs is upstream, "--with-kernel" shouldn't be needed, but +until then the path to where the kernel with the Orangefs kernel client +patch was made is needed to ensure that pvfs2-client-core (the bridge +between kernel space and user space) will build properly.
