HDF5

Description

HDF5 is a self-describing, portable, and hierarchical file format designed for high-performance I/O and featuring various integrated features that can help optimize storage space and access time. Because it can optimize system-tailored I/O at scale, HDF5 is widely used by industry, academic, and government organizations. It’s also highly compatible with other systems, making data sharing, collaboration, and analysis quick and trouble-free.

Impact, Sustainability, and Quality

Property	State
Impact	The HDF5 library is crucial for the large-scale data input/output process of the DOE. It is extensively used at all DOE computing facilities and relied upon by other I/O standards, libraries, and DOE research applications.
Sustainability	HDF has been developed for 25 years with significant government funding. This funding is used for new feature development, maintenance, documentation, and testing at DOE computing facilities.
Quality	The HDF5 library has well-established quality metrics, software, and testing processes.
