ABSTRACT
The GPFS is IBM’s parallel file system for high performance computing and data-intensive applications [7, 10]. GPFS is designed to enable seamless and efficient data sharing between nodes within and across small-to-large clusters using standard file system APIs and standard POSIX [1] semantics. At the same time, GPFS exploits the parallelism and redundancy available in a cluster to provide the large capacity, high performance, and high availability required by the most demanding scientific and commercial applications.
