High Performance Parallel I/O

<p><em>Gain Critical Insight into the Parallel I/O Ecosystem</em></p><p></p><p>Parallel I/O is an integral component of modern high performance computing (HPC) especially in storing and processing very large datasets to facilitate scientific discovery. Revealing the state of the art in this field <strong>High Performance Parallel I/O</strong> draws on insights from leading practitioners researchers software architects developers and scientists who shed light on the parallel I/O ecosystem.</p><p></p><p>The first part of the book explains how large-scale HPC facilities scope configure and operate systems with an emphasis on choices of I/O hardware middleware and applications. The book then traverses up the I/O software stack. The second part covers the file system layer and the third part discusses middleware (such as MPIIO and PLFS) and user-facing libraries (such as Parallel-NetCDF HDF5 ADIOS and GLEAN). </p><p></p><p>Delving into real-world scientific applications that use the parallel I/O infrastructure the fourth part presents case studies from particle-in-cell stochastic finite volume and direct numerical simulations. The fifth part gives an overview of various profiling and benchmarking tools used by practitioners. The final part of the book addresses the implications of current trends in HPC on parallel I/O in the exascale world.</p>
