Ai2's AI Infrastructure team replaced a priority-based GPU scheduler with a system using GPU time budgets, hierarchical fair-share allocation, and a time-slicing contract. The change shifted GPU time allocation from case-by-case operational decisions to a transparent administrative budgeting process, aiming to prioritize high-impact research while maintaining full cluster occupancy.

## Evidence

Verbatim from https://allenai.org/blog/impactful-scheduling:

> We recently replaced a priority-based scheduler with a system including GPU time budgets, hierarchical fair-share allocation, and a time-slicing contract. As a result, we shifted the debate about how much GPU time each research project deserves from a case-by-case operational task to a transparent administrative budgeting process.
