The AI Infrastructure team at the Allen Institute for Artificial Intelligence (Ai2) has developed a new scheduling system for their GPU clusters to improve the impact of resource allocation. This system replaces a problematic priority-based scheduler with features like GPU time budgets and hierarchical fair-share allocation. The team manages thousands of NVIDIA H100 and B200 GPUs for large-scale AI model training, facing demand that outstrips supply by 2-3x. The new approach aims to resolve issues like GPU squatting and priority inflation by shifting resource allocation from a case-by-case negotiation to a transparent budgeting process. AI
IMPACT Optimizes GPU cluster scheduling to ensure high-value AI research workloads receive priority, potentially accelerating scientific discovery.
