Halving Training Time: LoongForge Full‑Stack Optimizations Boost GR00T N1.6 Throughput 2.3×

LoongForge applies system‑level optimizations—async data prefetch, fine‑grained communication‑compute overlap via a Megatron distributed optimizer, and per‑microbatch CUDA Graph scheduling—to the GR00T N1.6 Vision‑Language‑Action model, delivering up to 2.3× higher training throughput and a 56.6% reduction in overall training time on an 8×A800 cluster.
