Abstract
GPFS is IBM's parallel, shared-disk file system for cluster computers, available on the RS/6000 SP parallel supercomputer and on Linux clusters. GPFS is used on many of the largest supercomputers in the world. GPFS was built on many of the ideas that were developed in the academic community over the last several years, particularly distributed locking and recovery technology. To date it has been a matter of conjecture how well these ideas scale. We have had the opportunity to test those limits in the context of a product that runs on the largest systems in existence. While in many cases existing ideas scaled well, new approaches were necessary in many key areas. This paper describes GPFS, and discusses how distributed locking and recovery techniques were extended to scale to large clusters.

Making resonance a common case: A high-performance implementation of collective I/O on parallel file systems

TL;DR: Resonant I/O rearranges requests from multiple MPI processes according to the presumed data layout on the disks of I/o nodes so that non-sequential access of disk data can be turned into sequential access, significantly improving I/W performance without compromising the independence of a client-based implementation.

Scalability in the XFS file system

TL;DR: The architecture and design of a new file system, XFS, for Silicon Graphics' IRIX operating system is described, and the use of B+ trees in place of many of the more traditional linear file system structures are discussed.
