Abstract

Ever more frequently users of clusters find themselves in an interesting situation: it isn’t the processors, communication network, or memory that is limiting their application; it is the storage system. This might force the users to checkpoint less frequently than they would like, might limit the resolution of output visualization data, or might prevent the use of out-of-core solutions needed for the largest of problems. What’s worse, the I/O hardware in the system may indeed be adequate for the user’s needs but may be being used ineffectively by one of the many software layers involved. A lot of mystery surrounds I/O solutions in clusters today. For this reason we have rewritten this chapter in the second edition. We begin by covering what we believe are some of the most important issues in parallel I/O systems. These include parallel access patterns, parallel I/O system components and architectures, and consistency semantics. Knowing how parallel I/O systems operate and the issues involved can be useful when performance tuning an application for a particular system or choosing an I/O solution to match expected workloads.
