Abstract—Parallel file systems are designed to mask the everincreasing gap between CPU and disk speeds via parallel I/O processing. While they have become an indispensable compo...
Programs accessing disk-resident arrays, called out-of-core programs, perform poorly in general due to an excessive number of I/O calls and insufficient help from compilers. In ord...

This paper proposes methodologies to control the access of B-tree-indexed data in a batch and real-time fashion. Algorithms are proposed to insert, query, delete, and rebalance B-...
With an ever increasing amount of data to store, hierarchical storage management (HSM) systems must still use tape for tertiary storage. A disk cache is used to reduce the access ...
Noncontiguous data access is a very common access pattern in many scientific applications. Using POSIX I/O to access many pieces of noncontiguous data segments will generate a lot...
