The Parallel Virtual File System is a user-space parallel file system for use on clusters of PCs (and Beowulfs in particular). It provides transparent file striping across multiple machines and includes a loadable kernel module for use with existing binaries. TCP/IP is used for data transmission, and file data is stored on existing file systems on each machine. License: GNU General Public License (GPL) Changes:
Additional support for the latest Linux kernel versions. Improved performance for a number of metadata-intensive workloads, and improved support for multithreaded use of the system interfaces. A security layer has been implemented. This includes validation with credentials, conditional compilation for RSA, DSA, and no encryption, and private key loading and capability signatures. A deadlock bug has been fixed. file_aio_write_iovec has been implemented. There is code cleanup and minor bugfixes.
