Disaggregated Inference Frameworks

Evidence

NVIDIA uses Dynamo for its disaggregated inference setup. Dynamo is an inference framework designed for multi-node distributed inference, featuring techniques such as prefill-decode disaggregation, request routing, and KV cache offloading. It is inference-engine agnostic, allowing us to use SGLang and TRT LLM as backends in our benchmark. For AMD, we use SGLang with two different KV cache transfer frameworks: MoRI and Mooncake. MoRI is a high-performance communication interface focusing on RDMA and GPU integration, offering applications such as network collective operations and expert parallel kernels. Mooncake, which recently joined the PyTorch ecosystem , supports prefill-decode disaggregation and many fault tolerant multi-node features.
