<div dir="ltr"><div>Hello, </div><div><br></div>At p578 of the standard, <div><br></div><div>MPI_T_PVAR_HANDLE_ALLOC(session, pvar_index, obj_handle, handle, count)</div><div>...</div><div>OUT <span class="">count </span>number of elements used to represent this variable (integer)<br>
</div><div><br></div><div>It looks to me that pvar can have different classes, e.g., MPI_T_PVAR_CLASS_COUNTER, and datatypes, e.g., MPI_UNSIGNED. And a pvar can be an array (of length <i>count)</i> of such datatypes.</div>
<div><br></div><div>I guess the common case is count=1.</div><div><br></div><div>Is my understanding correct?</div><div><br></div><div>Thanks</div><div><br></div><div>--Junchao Zhang</div></div>
