The IDEAS Productivity project, in partnership with the DOE Computing Facilities of the ALCF, OLCF, and NERSC and the DOE Exascale Computing Project (ECP) has resumed the webinar series on Best Practices for HPC Software Developers, which we began in 2016.

As part of this series, we offer one-hour webinars on topics in scientific software development and high-performance computing, approximately once a month. The next webinar was titled Parallel I/O with HDF5: Overview, Tuning, and New Features, and was presented by Quincey Koziol (NERSC). The webinar took place on Wednesday, March 13, 2019 at 1:00 pm ET

Abstract:

HDF5 is a data model, file format, and I/O library that has become a de facto standard for HPC applications to achieve scalable I/O and for storing and managing big data from computer modeling, large physics experiments and observations. This webinar gave an introduction to using the HDF5 library, with a focus on parallel I/O and performance tuning options. The webinar also presented an overview of the latest performance and productivity enhancement features being developed as part of the DOE’s Exascale Computing Project (ECP) ExaHDF5 effort, and optimizations used in improving I/O performance of ECP applications.
