Key point
NVIDIA announced that Nemotron 3.5 Lightning generation speed on DGX Spark is up to 1.73 times faster when DSpark is applied.
Details
- NVIDIA published the execution and optimization procedures for Nemotron 3.5 Lightning using TensorRT Edge-LLM 0.11.1 in a DGX Spark 64GB environment.
- Applying DSpark speculative decoding improves generation speed by 1.45 to 1.73 times, with first token latency increasing by only 0.6 to 2.1ms, showing almost no change.
- Maximum acceleration was confirmed on the HumanEval coding benchmark, increasing from 73.4 tok/s to 126.9 tok/s.
- When deploying to other edge devices such as Jetson Thor, engine rebuilding is mandatory due to GPU architecture differences.
- The model features a 3B active MoE structure out of 30B parameters, and Korean is not included in the supported language list, being present only in the pre-training data.
- Running an OpenAI-compatible API server is experimental, with the default concurrent request limit set to 1.
