When One GPU Isn’t Enough: Serving GLM-5.3 Across Two NVIDIA DGX Stations with vLLM

A deployment approach using two NVIDIA DGX Stations connected via RDMA enables serving the large-scale GLM-5.3 NVFP4 model by distributing its weights and computation across multiple GPUs using tensor parallelism. This setup allows the model to be served through a unified endpoint despite exceeding the memory capacity of a single machine.
