SUMMARY:Parallel I/O In Practice: Part 1
DESCRIPTION:Tutorial\n\nParallel I/O In Practice: Part 1\n\nLatham, Ross, 
 Welch, Lockwood\n\nI/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 n
 ecessary for attendees to best leverage I/O resources available to them. W
 e cover the entire I/O software stack including storage and parallel file 
 systems at the lowest layer, the role of burst buffers (NVRAM), intermedia
 te layers (such as MPI-IO), and high-level I/O libraries (such as HDF-5). 
 We emphasize ways to use these interfaces that result in high performance,
  and tools for generating insight into these stacks.\n\nOur first third of
  the tutorial covers parallel I/O fundamentals. We discuss storage technol
 ogies, both present and near-future and the major parallel and distributed
  file systems.  We focus on application in our second third, connecting st
 orage to our examination of the upper library layers of the I/O stack; cov
 ering MPI-IO, Parallel netCDF and HDF5.  Finally, we discuss tools for und
 erstanding I/O behavior.\n\nTag: Best Practices, Data Movement, File Syste
 ms and I/O, Storage\n\nRegistration Category: Tutorial Reg Pass
