    <p>Hello</p>
    <p>Please note that netloc is dead. We stopped
      developing/maintaining it several years ago, and it's already
      removed from the hwloc git master branch.</p>
    <p>IIRC <a class="moz-txt-link-freetext" href="https://mvapich.cse.ohio-state.edu/userguide/osu-inam/">https://mvapich.cse.ohio-state.edu/userguide/osu-inam/</a> could
      help here, no idea if it's still maintained.</p>
    <p>Brice<br>

              outputs what i need (though i only need the CA
              perspective), but it's<br>
              going to be an atrocious effort in text parsing.   would
              be nice if<br>
              there was a nice simple command, preferably that outputs
              json, but<br>
              that's likely wishful thinking<br>
