<p class=""><i> Advice to implementors.</i> Groups of variables that belong closely together, but have different classes, can have the same name. This choice is useful, e.g., to refer to multiple variables that describe a single resource (like the level, the total size, as well as high and low watermarks). (End of advice to implementors.)</p>
<p class="">It implies pvar names are not unique among pvar classes. So we need to require unique pvar names, or add a pvar class argument to MPI_T_PVAR_GET_INDEX.</p></div><div><div dir="ltr">--Junchao Zhang</div></div>
