Hierarchical Data Format library (from NCSA) 1.8

HDF5 is a completely new Hierarchical Data Format product consisting of a data format specification and a supporting library implementation. HDF5 is designed to address some of the limitations of the older HDF product and to address current and anticipated requirements of modern systems and applications.

HDF5 includes the following improvements

  • A new file format designed to address some of the deficiencies of HDF4.x, particularly the need to store larger files and more objects per file.
  • A simpler, more comprehensive data model that includes only two basic structures a multidimensional array of record structures, and a grouping structure.
  • A simpler, better-engineered library and API, with improved support for parallel I/O, threads, and other requirements imposed by modern systems and applications.

Note two releases of HDF5 are available. HDF5-1.10 can read files created with earlier releases, but earlier releases such as HDF5-1.8 may not be able to read HDF5-1.10 files. If you need the latest, please see the port science/hdf5.
