This article discusses pNFS (parallel NFS), a protocol that is being standardized as part of the NFSv4.1 specification to bridge the gap between current NFS protocols and parallel cluster file system interfaces.

Data-intensive applications such as data mining, movie animation, oil and gas exploration, and weather modeling generate and process huge amounts of data. File-data access throughput is critical for good performance. To scale well, these HPC (high-performance computing) applications distribute their computation among numerous client machines. HPC clusters can range from hundreds to thousands of clients with aggregate I/O demands ranging into the tens of gigabytes per second.
