</div>No. You shouldn't need to run mpd at all.<br>
<br>

an annoying mpdboot step that is fragile and difficult to use<br>
correctly. The mpd process manager is deprecated at this point ..."<br>
<br>
Perhaps when you typed "mpiexec", you were not really running the<br>
mpiexec binary that you had just built, but rather some other (really<br>
old) version that was already lying around on your system?<br>
<br>
I'd suggest:<br>
running "which mpiexec" and "mpiexec --version"<br>
checking your $PATH<br>
specifying an absolute pathname to the new mpiexec binary instead<br>
of just "mpiexec"<br>
<br>
Hope this helps,<br>
Nicolás<br></div></div>
