The HDF Group’s technical mission is to provide rapid, easy and permanent access to complex data. FishEye's vision is "Synthesizing the world’s real-time data". This white paper is intended for embedded system users, software engineers, integrators, and testers that use or want to use HDF5 to access, collect, use and analyze machine data. FishEye has developed an innovative process that provides the most efficient method to expose data from embedded systems that simplifies and liberates data for real-time analysis, machine learning, and cloud-enabled services....

HSDS (Highly Scalable Data Service) is a REST-based service for reading and writing HDF data. Initially developed as a NASA Access 2015 project, the HDF Group has continued to invest in the project, and as we'll see, the latest version has a bevy of new and interesting features....

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....

Why do we use HDF5? We moved to HDF5 for our simulation data in 2016 from using our own proprietary file format. HDF5 had been on our radar for some time and we spent a couple of years investigating it and other file formats before deciding which we should switch to. HDF5 met all the criteria we had at the time. Amongst the criteria were: performance in speed and size, an accepted standard for scientific data, being open source, providing additional tools....

With MyIRE and HDF, everyone from a doctor in a small-town office to big data genetics researchers can work together to find new and powerful insights across data sets using a common set of tools - and do so in a repeatable way. And, because of HDF5, any user—whether large or small—is powered by the same technology used by CERN and NASA. We knew we wanted all of MyIRE’s users to have the power of NASA in their pocket. HDF5 made that possible....

Reproducibility in computing has important impacts in data sets of all shapes and sizes.  HDF provides high throughput interfaces to data sets in a reproducible way. Using HDF allows MyIRE users to analyze data across experiments and domains.  Methods, techniques, and case studies for using and increasing access to HDF will be presented. Please join us for a webinar with the team at MyIRE on Tuesday, February 12th, at 10:00 a.m. CST. Register now!...
