Dynamo 1.0 Powers Multi-Node Inference

🔑 Enhanced Key Takeaways

• •NVIDIA Dynamo is open-source and supports inference engines like SGLang, TensorRT-LLM, and vLLM for modular distributed serving[5][6].
• •Features disaggregated prefill and decode phases, dynamic GPU scheduling, and LLM-aware request routing to optimize throughput and latency[2][3].
• •Integrates with NVIDIA Run:ai for gang scheduling and topology-aware placement, and with Grove for Kubernetes-based multi-node deployments[2][5].
• •Includes Dynamo Planner Profiler and SLO-based Planner for automated GPU allocation and rate matching in disaggregated inference on AKS[3][4].

🛠️ Technical Deep Dive

• •Disaggregates prefill (input processing) and decode (token generation) phases across separate GPU pools for independent optimization using custom tensor parallelism (TP) configurations[2][3][4].
• •Employs LLM-aware request routing to reuse KV caches and avoid recomputation, alongside dynamic scheduling for fluctuating workloads[2][6].
• •Dynamo Planner Profiler tests TP sizes, simulates hardware performance via AI Configurator (AIC) in 20-30 seconds, and identifies optimal GPU ratios for TTFT and ITL[3].
• •SLO-based Planner automates scaling based on latency targets, handling traffic spikes in Kubernetes environments like AKS[3][4].
• •Supports topology-optimized serving via Grove Kubernetes API for declarative startup of interdependent components and NVLink-enabled systems like GB200 NVL72[5].
