Instant GPU Efficiency Visibility at Fleet Scale
Researchers have developed a new metric called Overall FLOP Utilization (OFU) to measure GPU efficiency for AI workloads. OFU is derived from on-chip performance counters and does not require application instrumentation, making it applicable across different GPU generations and precisions. When tested on production training jobs, OFU showed a strong correlation with application-level metrics and helped identify efficiency regressions and framework miscalculations. AI
