In the 1990s, high performance computing (HPC) made a dramatic transition to massively parallel processors. As this model solidified over the next 20 years, supercomputing performance increased from gigaflops—billions of calculations per second—to petaflops—quadrillions of calculations per second—generating a tsunami of data along the way.

In this era of “big data,” high performance parallel I/O—the way disk drives efficiently read and write information on HPC systems—is extremely important. Yet, the last book to summarize best practices in this area was written more than 10 years ago. To fill the void, Prabhat of the Lawrence Berkeley National Laboratory (Berkeley Lab) and Quincey Koziol of the HDF Group brought together leading practitioners, researchers, software architects, developers and scientists to contribute their insights for a new book called “High Performance Parallel I/O.”

Published on October 24, the editors will be signing copies of the book and answering questions in the Department of Energy’s booth (#1939) at SC14 (Supercomputing Conference, 2014) on Tuesday, November 18 at 5:15-6:00 p.m.

“This book provides a survey of the significant accomplishments in file systems, libraries and tools that have been developed for about a decade. These developments have now reached a state of relative maturity and are ripe for a treatment in book format,” writes Horst Simon, Deputy Director of Berkeley Lab in the book’s forward. “I highly recommend this timely book for computational scientists and engineers.”

According to Prabhat, the book is divided into six parts. The first part explains how large-scale HPC facilities scope, configure, and operate systems, with an emphasis on choices of I/O hardware, middleware, and applications. It then traverses up the I/O software stack. The second part covers the file system layer and the third part discusses middleware and user-facing libraries.

Delving into real-world scientific applications that use the parallel I/O infrastructure, he notes that 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, addresses the implications of current trends in HPC on parallel I/O in the exascale world.

“This book is a soup to nuts collection of everything you need to know about high performance parallel I/O, from hardware all the way up into the software layers and future work,” says Koziol.

About Computing Sciences at Berkeley Lab

High performance computing plays a critical role in scientific discovery, and researchers increasingly rely on advances in computer science, mathematics, computational science, data science, and large-scale computing and networking to increase our understanding of ourselves, our planet, and our universe. Berkeley Lab’s Computing Sciences Area researches, develops, and deploys new foundations, tools, and technologies to meet these needs and to advance research across a broad range of scientific disciplines.

Founded in 1931 on the belief that the biggest scientific challenges are best addressed by teams, Lawrence Berkeley National Laboratory and its scientists have been recognized with 13 Nobel Prizes. Today, Berkeley Lab researchers develop sustainable energy and environmental solutions, create useful new materials, advance the frontiers of computing, and probe the mysteries of life, matter, and the universe. Scientists from around the world rely on the Lab’s facilities for their own discovery science. Berkeley Lab is a multiprogram national laboratory, managed by the University of California for the U.S. Department of Energy’s Office of Science.

DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. For more information, please visit energy.gov/science.
