Optimizing Inference with Parameter/Data (P/D) Separation in vLLM Framework

Large language models often encounter GPU memory bottlenecks during inference deployment: Model parameters (P) can reach hundreds of GB and must remain resident in GPU memory. Input/output data (D) changes dynamically with each request but is often coupled with parameters on the same device, leading to imbalanced memory usage and limited scalability. To solve this problem, we can leverage the vLLM framework to implement Parameter/Data (P/D) Separation, improving the flexibility and throughput of inference systems....
