# Multi XPU (GLM-5-W8A8-INT8)

## Run vllm-kunlun on Multi XPU

Setup environment using container:

Please follow the [installation.md](../installation.md) document to set up the environment first.

Create a container
```bash
# !/bin/bash
# rundocker.sh
XPU_NUM=8
DOCKER_DEVICE_CONFIG=""
if [ $XPU_NUM -gt 0 ]; then
    for idx in $(seq 0 $((XPU_NUM-1))); do
        DOCKER_DEVICE_CONFIG="${DOCKER_DEVICE_CONFIG} --device=/dev/xpu${idx}:/dev/xpu${idx}"
    done
    DOCKER_DEVICE_CONFIG="${DOCKER_DEVICE_CONFIG} --device=/dev/xpuctrl:/dev/xpuctrl"
fi

export build_image="xxx"

docker run -itd ${DOCKER_DEVICE_CONFIG} \
    --net=host \
    --cap-add=SYS_PTRACE --security-opt seccomp=unconfined \
    --tmpfs /dev/shm:rw,nosuid,nodev,exec,size=32g \
    --cap-add=SYS_PTRACE \
    -v /home/users/vllm-kunlun:/home/vllm-kunlun \
    -v /usr/local/bin/xpu-smi:/usr/local/bin/xpu-smi \
    --name "$1" \
    -w /workspace \
    "$build_image" /bin/bash
```

### Preparation Weight

- Pull GLM-5-W8A8-INT8 weights
  ```
  wget -O GLM-5-W8A8-INT8-Dynamic.tar.gz https://aihc-private-hcd.bj.bcebos.com/LLM/AICapX-Quant-Models/GLM-5-W8A8-INT8-Dynamic.tar.gz
