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.
|
|
|
|
Why HDF5? The development of HDF5 is motivated by a
|
|
number of limitations in the older HDF format and library.
|
|
|
|
HDF5 includes the following improvements over HDF4
|
|
|
|
o 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.
|
|
o A simpler, more comprehensive data model that includes only two
|
|
basic structures: a multidimensional array of record structures,
|
|
and a grouping structure.
|
|
o A simpler, better-engineered library and API, with improved
|
|
support for parallel I/O, threads, and other requirements imposed
|
|
by modern systems and applications.
