Szip compression software, providing lossless compression of scientific data, is provided with HDF software products as of HDF5 Release 1.6.0 and HDF4 Release 2.0.

Szip is an implementation of the extended-Rice lossless compression algorithm. The Consultative Committee on Space Data Systems (CCSDS) has adopted the extended-Rice algorithm for international standards for space applications. Szip is reported to provide fast and effective compression, specifically for the EOS data generated by the NASA Earth Observatory System (EOS). It was originally developed at University of New Mexico (UNM) and integrated with HDF4 by UNM researchers and developers.

For more information see the SZIP Website.


Szip is available as a module. There are modules for both xeon and mic builds.

Once the Szip module has been loaded, it can be linked against it with
