Why should I care about the HDF5 1.10.2 Release?

HDF Server: Best Use of HPC in the Cloud – vote in HPCwire’s 2016 Readers’ Choice Awards
The HDF Group’s HDF Server has been nominated for Best Use of HPC in the Cloud, and Best HPC Software Product or Technology in HPCWire’s 2016 Readers’ Choice Awards. HDF Server is a Python-based web service that enables full read/write web access to HDF data – it can be used to send and receive HDF5 data using an HTTP-based REST interface. While HDF5 provides powerful scalability and speed for complex datasets of all sizes, many HDF5 data sets used in HPC environments are extremely large and cannot easily be downloaded or moved across the internet to access data on an as-needed basis. Users often only need to access a small subset of the data. Using HDF Server, data can be kept in one...

To Serve and Protect: Web Security for HDF5
John Readey, The HDF Group
| Editor’s Note: Since this post was written in 2015, The HDF Group has developed Kita, a new product that addresses the challenges of adapting large scale array-based computing to the cloud and object storage while intelligently handling the full data management life cycle. If this is something that interests you, we’d love to hear from you. |
HDF Server is a new product from The HDF Group which enables HDF5 resources to be accessed and modified using Hypertext Transfer Protocol (HTTP).
HDF Server [1], released in February 2015, was first developed as a proof of concept that enabled remote access to HDF5 content using a RESTful API. HDF Server version 0.1.0 wasn’t yet intended for use in a production environment since it didn’t initially provide a set of security features and controls. Following its successful debut, The HDF Group incorporated additional planned features. The newest version of HDF Server provides exciting capabilities for accessing HDF5 data in an easy and secure way.
