# Kimi-K3 SGLang multi-node TP=32 EP=32 deployment profile (4x RTX 6000D).
# Nodes: 174.1.60.5~8 (rank 0~3), 32x NVIDIA RTX 6000D (85GB, sm_120).
#
# 关键点（实测踩坑，勿随意改）:
#   - MoE 后端必须 marlin（K3 的 MXFP4 缩放因子为 uint8，DeepGEMM 只接受 fp32/UE8M0）
#   - RoCE: NCCL_IB_HCA=mlx5_0..3（4 张独立卡, 10.100.21-24/24, RoCEv2 GID index 3）
#     实测 32-rank 117MB allreduce 2.4ms；勿用 mlx5_bond_0（仅 4.5GB/s）
#   - 容器必须 --ulimit memlock=-1（否则 ibv_create_cq 报 Cannot allocate memory）
#   - 不要设 NCCL_ALGO=TREE（CUDA graph 捕获报 "NCCL error: invalid usage"）
#   - 首次请求含 ~110s Triton JIT 编译，属正常现象，预热一次后回落
#   - flashkda 可选后端（与 triton prefill 性能等价）见 docs/KIMI_K3_DEPLOY.md 附录
#
# Model-team only. Ops only run `python -m sskj.bench` against the served URL.
