# HDF5

Hierarchical Data Format version 5 (HDF5) is a file format used for portable, accessible storage of large amounts of data in a hierarchical, filesystem-like format. The HDF5 libraries available on Aire support C, C++, Fortran and Java. More information is available in the [official documentation](https://support.hdfgroup.org/documentation/hdf5/latest/).

## The HDF5 module on Aire

Aire offers three versions of HDF5; one base versions, and two compiled for use on top of different versions of OpenMPI:
