Maximizing GPU Utilization: From Allocation to FLOP/s

This article delves into three levels of GPU utilization: GPU Allocation Utilization, GPU Kernel Utilization, and Model FLOP/s Utilization. The authors highlight the importance of maximizing GPU utilization given their high cost and performance sensitivity. The article analyzes factors affecting utilization at each level, such as economic limitations, DevOps limitations, and host overhead, and proposes optimization strategies like using the Modal platform for improved GPU allocation efficiency, optimizing kernel code, and increasing arithmetic intensity. Finally, the article shares the current state of GPU utilization in the industry and best practices, providing valuable experience and guidance for developers.
