The HDF Community

The HDF Group is excited to announce we're participating in the Exascale Computing Project (ECP) 2023 Community Birds-of-a-Feather (BOF) Days. Make sure to join the HDF5 session, HDF5: Pre-ECP, Present, and Future on February 14....

The HDF Group hosted, Loïc Huder of ESRF for a webinar on Vscode-h5web: A VSCode extension to explore and visualize HDF5 files on August 31, 2022. H5Web is a web viewer for HDF5 files. It can be used to browse HDF5 files and display datasets with performant WebGL-based visualisations. While such files can be requested from a separate server (e.g. HSDS) for modularity, it is now possible to load and explore a file fully in the browser by using a WebAssembly HDF5 library called h5wasm. In this talk, presenter Loïc Huder will show how the team leveraged h5wasm to design a VSCode extension that uses H5Web to explore and visualize HDF5 files. Once the H5Web extension is installed, exploring and visualising...

The purpose of this introduction is to highlight and celebrate a community contribution the impact of which we are just beginning to understand. Its principal author, Mr. Lucas C. Villa Real, calls it HDF5-UDF and describes it as "a mechanism to generate HDF5 dataset values on-the-fly using user-defined functions (UDFs)." This matter- of-fact characterization is quite accurate, but I would like to provide some context for what this means for us users of HDF5....

The group at BioSimulations.org has been doing some very interesting work using HSDS on Kubernetes to store biomodelling data and visualizing the results using Vega as described in the paper below. Biosimulations chose to use HSDS due to its support for very large data sets,  REST API (for use with web applications), and its ability to run on Google Cloud as well as on-premise installations. ...

Hermes is a distributed I/O buffering system for deep distributed storage hierarchies, which are commonly found on modern HPC systems. On December 1st, 2021, members of the Hermes team gave a presentation to show Hermes in action, talk about the new release and plan for future development. Here are the materials from that session: Slide Deck - Part I - Intro, Overview, and FAQ Slide Deck - Part II - Demonstration https://youtu.be/zDmUdynklJs    ...
