sorry if this is an uninvited feedback

I was reading this — https://github.com/Quansight/open-gpu-server/blob/main/docs/openstack.md#iommu-groups , did you try enbling ACS in server's BIOS? It should be able to increase the number of IOMMU groups

Hey @tryauuum thanks for the feedback, highly appreciate it.

While playing with the IOMMU groups, I did looked at ACS override patch for more IOMMU groups. The ACS override doesn’t actually changes the groups. It just changes how they appear to Linux, which may and may not work and either ways it's a nightmare for stability, and stability is really very important for a CI system and this is why we didn't take that path.
