The I/O demands of many applications have outpaced the capabilities of I/O subsystems, especially for extreme scale systems. This situation is expected to only get worse as the community moves toward exascale systems. The ORNL Future Technologies Group has been investigating these extreme-scale I/O challenges. We study application I/O demands (including how best to determine these demands), how well current and expected I/O solutions meet these demands, and how to address the gap between application demands and achievable performance.
