This is touched on in this bug
https://bugs.schedmd.com/show_bug.cgi?id=7834 where it appears at one
point MPS appeared to work for multiple users.
It may be that the side-channel attack via performance counters when
sharing NVIDIA GPUs between users caused them to rethink that
(speculating here, but would make a lot of sense). That was
CVE‑2018‑6260 patched back in February.
All the best,
