Hi Jeff,
<div><br>
</div>
<div> Thanks. Pardon my ignorance but I I wanted to just use MPE with an existing OpenMPI installation and it's not clear to me ( even after searching and reading ), how to do that from the full MPICH code base at that repo. I can't really even find MPE in
that code at all. What am I missing?</div>
<div><br>
</div>
<div> Thanks</div>
<div><br>

Thanks, Jeff. The actual function definitions should be modified as well, which your patch seems to miss.<br>
<br>
But I think the potentially time consuming part is to get buy-in from all the ABI consortium folks for this change. It doesn't exactly break ABI for applications, but will be an annoying change for tools. Ken is looking into this.<br>
