the Parallel Virtual File System (PVFS) is a high-performance and scalable parallel file system for clusters. PVFS is open source and released under the GNU General Public License. It requires no special hardware or modifications to the kernel. PVFS provides four important capabilities in one package: a consistent file name space across the machine transparent access for existing utilities physical distribution of data across multiple disks in multiple cluster nodes high-performance user space access for applications

PVFS is an Open Source parallel file system. A parallel file system is a type of distributed file system that distributes file data across multiple servers and provides for concurrent access by multiple tasks of a parallel application. PVFS was designed use in large scale cluster computing.

Stands for Post Viral Fatigue Syndrome. Rough synonym for Chronic Fatigue Syndrome, but tends to be used where the illness is of a shorter duration and less severe.
