SUMMARY:High Performance I/O Frameworks 101
DESCRIPTION:Scott Klasky (Oak Ridge National Laboratory), Qing Liu (New Je
 rsey Institute of Technology), Manish Parashar (Rutgers University), Norbe
 rt Podhorszki and David Pugmire (Oak Ridge National Laboratory), and Keshe
 ng Wu (Lawrence Berkeley National Laboratory)\n\nAs concurrency and comple
 xity continue to increase on high-end machines, I/O performance is rapidly
  becoming a fundamental challenge to achieving exascale computing. Wider a
 doption of higher-level I/O abstractions will be critically important to a
 ddress this challenge. Modern I/O libraries provide data models, portable 
 APIs, storage abstractions, and self-describing data containers. They achi
 eve high performance and scalability, allow data to be managed more effect
 ively throughout the data lifecycle, and enable reproducible science. \n\n
 Part I of this tutorial will provide an overview of parallel I/O systems a
 nd summarize the key techniques for obtaining high performance I/O on high
 -performance computing (HPC) resources at scale. Part II introduces ADIOS 
 and HDF5 libraries, delving through their usage models and examples, showi
 ng how to achieve high performance scalable I/O. Part III explains data co
 mpression. Part IV covers techniques for creating in situ analytics and te
 aches how to generate visualization services using VTK-M.  Finally, Part V
  will explain data indexing/querying and how to use the libraries to query
  data both in situ and on files. Over one half of this tutorial will be ha
 nds-on sessions, where we provide access to the software and go through li
 ve examples.\n\nInstructions for installing software for the tutorial: htt
