In this video from the 2017 Argonne Training Program on Extreme-Scale Computing, Phil Carns from Argonne presents: HPC I/O for Computational Scientists.
“Darshan is a scalable HPC I/O characterization tool. It captures an accurate but concise picture of application I/O behavior with minimum overhead.”
Darshan was originally developed on the IBM Blue Gene series of computers deployed at the Argonne Leadership Computing Facility, but it is portable across a wide variety of platforms include the Cray XE6, Cray XC30, and Linux clusters. Darshan routinely instruments jobs using up to 786,432 compute cores on the Mira system at ALCF.
Philip Carns is a principal software development specialist in the Mathematics and Computer Science division of Argonne National Laboratory and a fellow of the Northwestern-Argonne Institute of Science and Engineering. He received his Ph.D. in computer engineering from Clemson University in 2005. His research interests include development, measurement, and simulation of large-scale storage system.
