/** \page collective_calls Collective Calling Requirements in Parallel HDF5 Applications
*
* \section sec_collective_calls_intro Introduction
* This document addresses two topics of concern
in a parallel computing environment:
<ul><li>HDF5 functions that must be called collectively and when
<li>Properties that must be used in a coordinated manner
</ul>
The term <i>@ref options</i> in the "Additional notes"
column indicates that the first item in the "Function"
column of the same row is a macro that is selectively mapped to one
of the two immediately-following functions.
For example, #H5Acreate is a macro that can be mapped to
either #H5Acreate1 or #H5Acreate2.
This mapping is configurable and is explained in
\ref api-compat-macros.
The macro structure was introduced at HDF5 Release 1.8.0.
*
* \section sec_collective_calls_func Always collective
* The following functions must always be called collectively.
