GPU Utilization Analysis and Optimization for Alibaba's Intelligent Creative Video Service

The paper analyzes why Alibaba Mama’s intelligent creative video service suffers low GPU utilization—due to Python GIL blocking, lack of kernel fusion, and serialized CUDA streams—and details service‑level changes (separate CPU/GPU processes, shared‑memory queues, priority scheduling) and operator‑level kernel‑fusion techniques (channels‑last layouts, custom pooling, TensorRT conversion) that raise utilization from ~30 % to near 100 % and boost throughput by 75 %.
