I would assume that this will need sophisticated programming, as the

one CPU by a GPU will still make the other processes not faster and the fast

I wonder about the variance in mathematical precision whether the CPU or a GPU
is used too.
All good points. I think I need to do some testing before enabling this
globally on our system. There may be a good chance that it may produce
some weird side effects in terms of GPU resource contention and possibly
mathematical inaccuracies as you've noted.
Rajil, if you get a chance to do some testing in this regard, please
report back and share with the group.
This may well turn out to be one of those things that we "can" do, but
probably "shouldn't" do.
Thanks,
