Jobs requesting TPU resources may also have requests for CPU and memory. However when pathways is enabled, Kueue will not be able to admit such jobs since there is no cpu and memory quota. This fix adds a very high number of CPU and memory for TPU/GPU resources and merges the pathways resource group with the accelerator resource group. This also allows us to run AXLearn jobs without having to make changes manually.
Otherwise the pathways head pod will not first get assigned to CPU only resource flavors.

Seems @lukebaumann encountered an issue when not using |
|
Seems NAP without pathways is also impacted. I think we need a different fix. See #603 |
|
This PR should solve NAP and AXLearn support as well. Would prefer to get this merged and will check with Luke on why it wasn't working for him. |

It's still needed for us to be able to run AXLearn on xpk clusters. |

I think it's set in xpk/src/xpk/core/kueue_manager.py Line 324 in f0626b9 |
