SUMMARY:Parallel I/O In Practice: Part 2
DESCRIPTION:Tutorial\n\nParallel I/O In Practice: Part 2\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). W
 e emphasize ways to use these interfaces that result in high performance a
 nd tools for generating insight into these stacks. Benchmarks on real syst
 ems are used throughout to show real-world results.\n\nIn the first third 
 of the tutorial we cover the fundamentals of parallel I/O. We discuss stor
 age technologies, both present and near-future. Our parallel file systems 
 material covers general concepts and gives examples from Lustre, GPFS, Pan
 FS, HDFS, Ceph and Cloud Storage. Our second third takes a more applicatio
 n-oriented focus. We connect storage to our examination of the upper libra
 ry layers of the I/O stack, covering MPI-IO, Parallel netCDF and HDF5. We 
 discuss interface features, show code examples and describe how applicatio
 n calls translate into PFS operations. Finally, we discuss tools for captu
 ring and understanding I/O behavior.\n\nTag: Best Practices, Data Movement
