Abstract

This paper will summarize an IO1 performance analysis effort performed on Sandia National Laboratories Red Storm platform. Our goal was to examine the IO system performance and identify problems or bottle-necks in any aspect of the IO sub-system. Our process examined the entire IO path from application to disk both in segments and as a whole. Our final analysis was performed at scale employing parallel IO access methods typically used in High Performance Computing applications.
