 \*\*Note: \*\* tp can be configured to enable TensorParallel inference on several gpus, suitable for the inference of very large models.
+
 \*\*Note: \*\* The max_total_token_num in the above command will affect the throughput performance during testing. It can be configured according to the documentation on the [Lightllm homepage](https://github.com/ModelTC/lightllm). As long as it does not run out of memory, it is often better to set it as high as possible.
 
+\*\*Note: \*\* If you want to start multiple LightLLM services on the same machine, you need to reconfigure the above port and nccl_port.

 You can use the following Python script to quickly test whether the current service has been successfully started.

 ```
 
 **注：** 上述命令可以通过 tp 的数量设置，在 tp 张卡上进行 TensorParallel 推理，适用于较大的模型的推理。
+
 **注：** 上述命令中的 max_total_token_num，会影响测试过程中的吞吐性能，可以根据 [Lightllm 主页](https://github.com/ModelTC/lightllm) 上的文档，进行设置。只要不爆显存，往往设置越大越好。
 
+**注：** 如果要在同一个机器上起多个 Lightllm 服务，需要重新设定上面的 port 和 nccl_port。
+
 可以使用下面的 Python 脚本简单测试一下当前服务是否已经起成功
