Webinars

On January 19, 2021 The HDF Group participated in the NCSA’s Webinar series, The University of Illinois New Frontiers Initiative Webinar Series with sessions presented by Gerd Heber, John Readey, and Aleksander Jelenak. HDF Technologies and Resources for Geospatial Data Abstract: The HDF Group created HDF at NCSA in 1988 to enable scientists and engineers to describe, store, and access large, complex data structures and collections. Since then we have worked with data producers, providers, and users all over the world and in every discipline to develop and evolve HDF to meet the needs of changing technologies and applications. Applications as diverse as gravity wave detection, gene sequencing, and finance use the HDF5 data model and software to acquire and share data and solve...

On February 12, 2021, we were pleased to host Lucas Villa Real of IBM Research to discuss his project HDF5-UDF, a data virtualization tool for HDF5. The tool enables users to associate logic in source code form (i.e., in user-defined functions, written in Python, C/C++, or Lua) with HDF5 datasets. Such UDFs are compiled into a binary form (which often takes no more than a few KB) and embedded into HDF5; once an application reads such a dataset, HDF5-UDF executes that binary code and generates the data on-the-fly. Lucas has just released HDF5-UDF 1.2 which offers several new features: among other benefits, it makes it possible to easily virtualize CSV files so they look like regular HDF5 datasets. Attached you'll find the slide deck...

On Friday, July 31, The HDF Group employee Chen Wang presented a Study of HACC-IO Benchmarks. We wanted to share these presentations with our community. Slide Deck https://youtu.be/AkcOwg3qLZo   Additionally, Chen Wang also wrote the white paper, An I/O Study of ECP Applications....
