The HDF Group’s Gerd Heber hosts a weekly session where he tries to answer attendee questions and, for example, go over the previous week’s HDF Forum posts. The HDF Clinics are free sessions intended to help users tackle real-world HDF problems from a common cold to severe headaches and offer relief where that’s possible. As time permits, we will include how-tos, offer advice on tool usage, review your code samples, teach you survival in the documentation jungle, and discuss what’s new or just around the corner in the land of HDF. Please submit questions/topics in this google doc. One-time registration required. Thanks to all who attended our first HDF Clinic on February 9, 2021. The resources from this clinic are archived here. Gerd's Notes https://youtu.be/g5h_YlvI9Aw  ...

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....

We are pleased to post this white paper from The HDF Group intern, Chen Wang. This paper looks at the steps of analyzing and tuning the HACC-IO benchmarks, the impact of different access patterns, stripe settings and HDF5 metadata. It also compares the five benchmarks on two different parallel file systems, Lustre and GPFS and shows that HDF5 with proper optimizations can catch up the pure MPI-IO implementations. An I/O Study of ECP Applications...
