Sorry about the long delay, but I think we've been going in circles for quite
a while now. Let's try to make it really simple as the first step. How about
something like the following?
* gpu.weight (should it be gpu.compute.weight? idk) - A single number
per-device weight similar to io.weight, which distributes computation
resources in work-conserving way.
* gpu.memory.high - A single number per-device on-device memory limit.
The above two, if works well, should already be plenty useful. And my guess is
that getting the above working well will be plenty challenging already even
though it's already excluding work-conserving memory distribution. So, let's
please do that as the first step and see what more would be needed from there.
Thanks.
