When GPU training demand exceeds physical capacity by 2x to 3x, replacing traditional priority-based queuing with hierarchical fair-share budgeting and strict time-slicing contracts is necessary to prevent GPU squatting and priority inflation. This operational shift automates resource allocation, eliminating the need for infrastructure engineers to manually negotiate preemptions and resolve cluster starvation. For teams shipping large-scale models, adopting this contract-based scheduling ensures predictable debugging access and continuous cluster occupancy without constant operational overhead.
Ai2 replaced a priority-based GPU scheduler with a system of time-slicing contracts and hierarchical fair-share budgeting to eliminate "GPU squatting" and priority inflation. This shifts resource contention from manual operational negotiations to a transparent administrative budget, ensuring high-impact workloads are prioritized without sacrificing total cluster occupancy.
