# Qwen3-30B-A3B fine-tuning with HybridEP token dispatch.
#
# HybridEP fuses permutation, communication, and expert permutation into
# a single step, reducing kernel-launch overhead compared to DeepEP.
#
# To run this recipe:
# automodel examples/llm_finetune/qwen/qwen3_moe_30b_te_hybridep.yaml --nproc-per-node 8
# Adjust --nproc-per-node to the number of GPUs available on your machine.
