National Facility for I/O Characterization and Optimization
Overview
I/O delays often limit the performance achieved with application codes on today's high-performance computers. Although the performance of both microprocessors and disks is increasing rapidly, both are not increasing at the same rate.Without a substantial base of empirical data on the I/O access patterns of single and multiple processor systems, researchers and educators can do little to overcome limitations imposed by I/O on the overall performance of emerging systems.
This facility is extending, documenting, archiving, and disseminating tools, sample applications, and experimental data to stimulate education and research on I/O system design, analysis, and optimization for large-scale commodity and workstation clusters, petascale systems, and distributed computational grids.
The National Facility for High-Performance I/O Characterization and Optimization is operated by the Pablo Research Group at the University of Illinois at Urbana-Champaign's Department of Computer Science under a grant to the U.S. National Science Foundation and is supported by funds from the National Science Foundation and the Department of Energy.
