LZ4 is a very fast lossless compression algorithm, providing compression speed at 300 MB/s per core, scalable with multi-cores CPU. It also features an extremely fast decoder, with speeds up and beyond 1GB/s per core, typically reaching RAM speed limits on multi-core systems. For a format description of the LZ4 compression filter in HDF5, see HDF5_LZ4.pdf.
Although the LZ4 software is not supported by The HDF Group, it is included in The HDF Group SVN repository so that it can be tested regularly with HDF5. For convenience, users can obtain it from SVN with the following command:
svn checkout https://svn.hdfgroup.org/hdf5_plugins/trunk/LZ4 LZ4
