DESCRIPTION:ABSTRACT: I/O on HPC systems is a black art. This tutorial sheds light on the state-of-the-art in parallel I/O and provides the knowledge necessary for attendees to best leverage I/O resources available to them. We cover the entire I/O software stack from parallel file systems at the lowest layer\, to intermediate layers (such as MPI-IO)\, and finally high-level I/O libraries (such as HDF-5). We emphasize ways to use these interfaces that result in high performance\, and benchmarks on real systems are used throughout to show real-world results.  This tutorial first discusses parallel file systems in detail (PFSs). We cover general concepts and examine four examples: GPFS\, Lustre\, PanFS\, and PVFS. We examine the upper layers of the I/O stack\, covering POSIX I/O\, MPI-IO\, Parallel netCDF\, and HDF5. We discuss interface features\, show code examples\, and describe how application calls translate into PFS operations. Finally we discuss I/O best practice.
