We have the need to discover which GPUs and NICs are close to which CPUs, independent from CUDA. From the overview page there are hints that there is some kind of support planned, but it's unclear to me of how much of this is implemented.
Is there support in hwloc, and in which version, for this? If yes, can you give me a hint/code snippet on how to do this? If no, what does it take to get this support in hwloc?
