<br>
to see your topology, you can use Netloc from hwloc:<br>
<a href="https://github.com/open-mpi/hwloc" target="_blank" rel="noreferrer">https://github.com/open-mpi/<wbr>hwloc</a><br>
See the image in attachment.<br>
<br>
You need to compile and install the whole project.<br>
Then, you will have a tool called netloc_ib_gather_raw that will use<br>
ibnetdiscover to collect data about your Infiniband network.<br>
This tool needs root access or at least access to the Infiniband device<br>
file (like ibnetdiscover).<br>
<br>
Then you need to convert your ibnetdiscover data into Netloc data with<br>
netloc_ib_extract_dats.<br>
<br>
Once it is done, the last step is to convert Netloc data into json<br>
format with netloc_draw_to_json.<br>
<br>
Now you will be able to open netloc_draw.html in your web browser and<br>
display your json file.<br>
<br>
Contact me if you have any question or problem about using it.<br>
<br>
Regards.<br>
<br>
<br>
Cyril.<br>
