While most large-scale LLM training systems are built around GPU-based clusters, this report presents an end-to-end optimization practice on the Ascend NPU SuperPOD. Using the DeepSeek-V4 model family as the target workload, we develop a hierarchical optimization framework spanning model-level parallelism, computation-communication orchestration, and low-level kernel execution. The resulting system achieves 34.22% Model FLOPs Utilization (MFU) with a 2.93x improvement over the open-source baseline recipe while maintaining training…","meta_description":"🤗 Upvotes: 51 | cs.CL, cs.AI Authors: Dongfang Li, Xiaodong Luo, Ruoyu Sun, Xuhui Chen, Linyuan Qiu, Jian Meng, Zhengxuan Lu, Yiting Wang, Yucheng Xie, Ta…","key_points":[],"chapters":[],"topics":[],"duration_seconds":1197,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/daily-paper-cast-7079649/episodes/slai-t-rex-full-parameter-post-training-of-the-deepseek-v4-family-on-ascend-superpod/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/daily-paper-cast-7079649/slai-t-rex-full-parameter-post-training-of-the-deepseek-v4-family-on-ascend-superpod.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
