This feature thread tracks the evolution of enabling high-performance AI inference across multiple GPUs and edge devices. Initial efforts focused on the challenges of scaling generative AI workloads beyond single-GPU memory and compute limits. TensorRT 11.0 introduced native multi-device inference support, leveraging NVIDIA NCCL for distributed collectives and enabling seamless scaling of generative AI pipelines. This includes the implementation of context parallelism strategies like AllGather KV, Ring Attention, and DeepSpeed Ulysses to efficiently handle long-sequence attention workloads, optimizing for compute, memory, and communication overhead. Benchmarks demonstrate significant latency improvements for diffusion-based media generation at extreme context lengths.
