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,
