Ai2 replaces priority-based GPU scheduler with budgeted fair-share and time-slicing
The Allen Institute for AI replaced its priority-based GPU scheduler with a system using GPU time budgets, hierarchical fair-share allocation, and a time-slicing contract to improve which projects receive scarce GPU resources while preserving occupancy. The change shifts allocation decisions from ad-hoc operational moves to a transparent administrative budgeting process across clusters of H100/B200/B300 GPUs serving ~150 researchers.
