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