TopicIO Pattern Characterization of HPC Applications
Abstract:  The HPC world is finally waking up to the importance of storage as an integral part of an HPC solution. However, the biggest problem that HPC centers face is that they don't understand how their applications perform IO (i.e. IO pattern) and how to then translate the results into useful requirements to define the hardware and file system for the HPC storage. In addition, the knowledge of the IO patterns allows the application developers to change the IO pattern to improve the IO performance. This talk presents a new technique for obtaining IO information and analyzing it to present IO pattern information.
