Hi Junchao,
<div><br>

<div> The MPI standard says "However, MPI implementations are not allowed to change the index of a performance variable or to delete a variable once it has been added to the set. When a variable becomes inactive, e.g., through dynamic unloading, accessing
its value should return a corresponding error code." Does it imply, </div>
<div> 1) MPI_T_pvar_get_num() will return a N that counts both active and inactive pvars</div>
</div>

<div><br>
</div>
Yes. <br>

<div dir="ltr">
<div> 2) MPI_T_pvar_get_info(par_index, ...,) may return MPI_T_ERR_INVALID_INDEX even for a par_index < N </div>

</div>
Yes.<br>

<div> 3) When a pvar is re-activated, it keeps its old index?</div>

Yes.<br>

<div> These are not obvious in the standard.</div>

Thanks for your feedback. We have updated the example for control variables (Example 14.4) to illustrate your first point (will be part of the next released standard). However, I realize now that we should do the same for other examples in the chapter.</div>
<div><br>
</div>
<div>We possibly need to add some text to address this as well, maybe as errata since it seems clarification could help avoid confusion. I'll bring this up in the working group.</div>
