I brought this KEP up with wg-device-management. It seemed to over well and they pointed out a few improvements.

I added this KEP to the wg-batch agenda next week. Maybe from there we can continue to discuss this KEP.

Yeah, I'm open to discussion. But, I will start to review this PR after the 0.9 release due to the 0.9 release tight deadline.

Forgive the naive question, still getting familiar with DRA. How does this work exactly? Does the resulting workload end up with 2 GPUs from this claim? Do we need to differentiate between the "time-slice" vs "space-partition" GPUs?

[kannon92]

So claims correspond to device classes. We can only limit device classes so I think you would set up a device with time-slicing enabled. Your claim would request this device.
