This H5Z-ZFP plugin supports ZFP versions 0.5.0 and newer.

This plugin uses the [*registered*](https://portal.hdfgroup.org/documentation/hdf5-docs/registered_filter_plugins.html)

HDF5 plugin filter id 32013

The  HDF5  filter  plugin  code here is also part of the Silo library.

However, we have made an  effort to also support  it as a  stand-alone

package  due  to  the  likely  broad  appeal  and  utility  of the ZFP

compression library.

This plugin supports all modes of the ZFP compression library, *rate*,

*accuracy*, *precision*, *expert* and *reversible*. It supports 1, 2, 3 and

4 dimensional datasets (for ZFP version 0.5.5 and newer) of single and double

precision integer and floating point data. It can be applied to HDF5 datasets

of more than 3 dimensions (or 4 dimensions for ZFP versions 0.5.5 and newer)

as long as no more than 3 (or 4) dimensions of the HDF5 dataset *chunking* are

of size greater than 1.
