We have scheduled a webinar for Friday, September 24 at 11:00 a.m. CDT covering the major new features of the HDF5 1.13.0 release. This will mainly cover pluggable virtual file drivers (VFDs) and changes to the virtual object layer (VOL). We'll also show how to build and use the async, pass-through, and cache VOL connectors. Registration is required....

On Friday, May 14, 2021, we hosted JP Swinski as he presented the webinar, H5Coro: The HDF5 Cloud-Optimized Read-Only Library. NASA’s migration of science data products and services to AWS has sparked a debate on the best way to access science data stored in the cloud. Given that a large portion of NASA’s science data is in the HDF5 format or one of its derivatives, a growing number of efforts are looking at ways to efficiently access H5 files residing in S3. This presentation describes one of those efforts and argues for the creation of a standardized subset of the HDF5 specification targeting cloud environments.

May 28, 2021 11:00 a.m. CDT Register In this webinar, we continue our exploration of Hermes. We will pick up where we left from the first webinar in which we showcased the Hermes API basics & adapters and showed how applications could benefit by using Hermes. We will run the popular VPIC kernel with Hermes and highlight the performance improvements due to the hierarchical buffering system. We will also present an HDF5 Virtual File Driver (VFD) for Hermes. All demonstrations will be accompanied by detailed performance analysis, and there will be time for audience questions and answers.

On Friday, April 30, The HDF Group's Gerd Heber presented HDF5 Application Tuning: There is more than one way to skin a cat(fish), Part 2. Before returning to application tuning (in part 3), in this second part of the series, we take a closer look at HDF5 performance variability. We highlight the main variability sources, their impact on performance, and considerations for HDF5 container design. https://youtu.be/JEnYLWpBjso...
