+## DeepInfer on AWS Trainium
+
+DeepInfer runs on Trainium2 through the native PyTorch `neuron` device (torch-neuronx 2.14, no torch-xla),
+structured like the Ascend port: `PlatformNeuron`, the `tilelang_ops/neuron` kernel backend and pure-torch
+drop-ins for DeepGEMM / FlashMLA / DeepEP / DeepSelect / TileKernels in `deepinfer/neuron_ops/vendor`.
+Design notes and conventions: [deepinfer/neuron_ops/NEURON_PORT.md](deepinfer/neuron_ops/NEURON_PORT.md).
+
+**Status — basic mode.** Eager execution; DSpark/MTP, zero-overhead scheduling, CP, EPLB, YOCO bounded replay and
+VL are off. EP > 1 runs on real neuron collectives. A tiny checkpoint in the real FP8/FP4 layout matches the
+official reference implementation within its own noise floor, on CPU and on a NeuronCore
+([examples/neuron](examples/neuron/README.md)). Performance work (static graphs, NKI kernels) and the remaining
+features are tracked in the [roadmap](https://github.com/whn09/DeepInfer/issues/19).
+
+On a Neuron DLAMI (trn2.48xlarge, SDK 2.33):
+
+``` bash
+bash tests/neuron/setup_trn2.sh          # venv on the DLAMI torch-neuronx env, build, tiny checkpoint + golden
+bash tests/neuron/run_all.sh cpu         # host-only tests
+CORES=0-7 bash tests/neuron/run_all.sh device
+```
+
+or build by hand in a venv layered on the DLAMI's torch-neuronx environment (the `torch-neuronx` wheel on the
+Neuron pip repository needs glibc >= 2.43, newer than Ubuntu 24.04's; the DLAMI ships a compatible build):
+
+``` bash
+python3.12 -m venv venv && echo "import site; site.addsitedir('/opt/aws_neuronx_venv_torch_neuronx_2_14_0/lib/python3.12/site-packages')" \
+  > venv/lib/python3.12/site-packages/zz_neuron.pth && source venv/bin/activate
+export PATH=$PATH:/opt/aws_neuronx_venv_torch_neuronx_2_14_0/bin   # neuronx-cc
+export DEEPINFER_ACCELERATOR=neuron
+./build.sh                               # requirements-neuron.txt (torch / torch-neuronx already satisfied) + C++ build
+python examples/neuron/offline_inference_neuron.py --model_name /path/to/DeepSeek-V4.1-Flash-1017 --ep 64
+```

+
+DeepInfer 通过原生 PyTorch 的 `neuron` 设备（torch-neuronx 2.14，不依赖 torch-xla）在 Trainium2 上运行，结构与
+Ascend 移植一致：`PlatformNeuron`、`tilelang_ops/neuron` kernel 后端，以及 `deepinfer/neuron_ops/vendor` 中
+DeepGEMM / FlashMLA / DeepEP / DeepSelect / TileKernels 的纯 torch 实现。设计说明与约定见
+[deepinfer/neuron_ops/NEURON_PORT.md](deepinfer/neuron_ops/NEURON_PORT.md)。
+
+**现状：basic mode。** 逐算子即时执行；DSpark/MTP、零开销调度、CP、EPLB、YOCO 有界重放和 VL 均关闭。EP > 1 使用
+真实的 neuron 集合通信。按真实 FP8/FP4 布局生成的小 checkpoint 在 CPU 和 NeuronCore 上都与官方参考实现一致（误差在
+参考实现自身的噪声范围内，见 [examples/neuron](examples/neuron/README.md)）。性能优化（静态图、NKI kernel）和其余特性
+在 [roadmap](https://github.com/whn09/DeepInfer/issues/19) 中跟踪。
+
+在 Neuron DLAMI（trn2.48xlarge，SDK 2.33）上：
+
+``` bash
+bash tests/neuron/setup_trn2.sh          # 基于 DLAMI 的 torch-neuronx 环境建 venv、编译、生成小 checkpoint 和真值
+bash tests/neuron/run_all.sh cpu         # 只用 host 的测试
+CORES=0-7 bash tests/neuron/run_all.sh device
+```
+
+或者在叠加于 DLAMI torch-neuronx 环境之上的 venv 里手动构建（Neuron pip 源上的 `torch-neuronx` wheel 需要
+glibc >= 2.43，比 Ubuntu 24.04 的版本新；DLAMI 自带的是兼容的构建）：
+
+``` bash
+python3.12 -m venv venv && echo "import site; site.addsitedir('/opt/aws_neuronx_venv_torch_neuronx_2_14_0/lib/python3.12/site-packages')" \
+  > venv/lib/python3.12/site-packages/zz_neuron.pth && source venv/bin/activate
+export PATH=$PATH:/opt/aws_neuronx_venv_torch_neuronx_2_14_0/bin   # neuronx-cc
+export DEEPINFER_ACCELERATOR=neuron
+./build.sh                               # requirements-neuron.txt（torch / torch-neuronx 已满足）+ C++ 编译
+python examples/neuron/offline_inference_neuron.py --model_name /path/to/DeepSeek-V4.1-Flash-1017 --ep 64
