最近在一台 8卡H20 机器上，先后部署了 DeepSeek-R1-AWQ （671B）和最新的 DeepSeek-V3-0324 (685B) ，测试了下性能和数学问题跑分。服务器由火山引擎提供。先来看一下机器配置：

这里踩过一个坑：最初的这个驱动版本有问题，在RTX4090上是好的，在H20上跑 DeepSeek-R1-AWQ 试过各种配置及软件版本，一推理就崩溃。后来换了NVIDIA官网为H20推荐的驱动版本 Driver Version: 550.144.03 （ CUDA 12.4）， 什么配置都没改就好了。

启动推理
用 vLLM v0.8.2 启动推理服务，分别先后启动如下两个模型的推理：
- DeepSeek-R1-AWQ： https://huggingface.co/cognitivecomputations/DeepSeek-R1-AWQ
- DeepSeek-V3-0324：https://modelscope.cn/models/deepseek-ai/DeepSeek-V3-0324
H20 性能评测
启动性能评测：
nohup python3 -u simple-bench-to-api.py --url http://localhost:7800/v1 \ --model DeepSeek-R1 \ --concurrencys 1,10,20,30,40,50 \ --prompt "Introduce the history of China" \ --max_tokens 100,1024,16384,32768,65536,131072 \ --api_key sk-xxx \ --duration_seconds 30 \ > benth-DeepSeek-R1-AWQ-8-H20.log 2>&1 &
这个命令会分别用 max_tokens 为100,1024,16384,32768,65536,131072， 来对1个并发，10个并发，。。。，50个并发，进行批量测试。每个max_tokens取值生成一个不同并发的表格。压测脚本 simple-bench-to-api.py 及详细参数含义在上一篇文章 《单卡4090上部署的DeepSeek-R1小模型的并发性能》 中有，需要的小伙伴可以自取。
压测结果：
8卡H20部署DeepSeek-R1-AWQ性能实测
----- max_tokens=100 压测结果汇总 -----
其中有几个概念需要解释下
- ”延迟“：从发出请求，到接收到最后一个token/字符的时间(包含了首字延迟时间)
- “P90延迟”：分位数90的延迟，计算方法为延迟从小到大排序，前90%的最大延迟值，和下一个延迟值，基于线性插值计算的一个介于2者之间的值。
- “首字延迟”：从发出请求，到接收到第一个返回字符的时间。
- “单并发吞吐量”的概念，是指站在每个并发用户/通道的角度看，从首token返回后，token的生成速度。统计时间不包含首字延迟。即一个通道的吞吐量 = 该通道生成的token数/除首token延迟外的生成时间。个人觉得，这个指标加上平均首字延迟，能反映真实的用户体感。
具体指标的含义：
- 平均延迟：所有通道的延迟平均值(包含了首字延迟时间)
- 单并发最小吞吐量： 所有并发通道中，吞吐量最小的通道的吞吐量(不包括首字延迟时间)
- 单并发最大吞吐量： 所有并发通道中，吞吐量最大的通道的吞吐量(不包括首字延迟时间)
- 单并发平均吞吐量：所有并发通道的吞吐量的平均值(不包括首字延迟时间)
- 总体吞吐量：在压测期间所有通道生成的tokens总数/压测开始到结束的时间

数学数据集跑分实测
用 GitHub - huggingface/lighteval: Lighteval is your all-in-one toolkit for evaluating LLMs across multiple backends 分别对部署在8卡H20上的 DeepSeek-R1-AWQ 和 DeepSeek-V3-0324 做了数学测试集跑分。这里我们修改了少量 lighteval 代码，让其不去自己启动模型推理，而是调用已经部署好的模型的OpenAI API接口。测试结果如下：

aime25 是比较新的，但是这个分数貌似低于之前别人公布过的评测分数。可能是评测方法的问题，也可能评测过程中上下文有截断影响结果。
