Abstract: The dominant paradigm for I/O interfaces and implementation in the supercomputing world is based on the POSIX standards. While this is well known to be sub-optimal, many acceptable mitigation strategies and alternative approaches have not yet been investigated. This talk will give a quick overview of a few current, popular, representative, system I/O architectures, application I/O strategies, and I/O middleware. Then, we will examine and discuss a consensus-based list of open problems in the field that is used by various U.S. government agencies, such as DOE and NSF, to motivate research proposals.
