# vllm-auto-test
# vLLM 0.9.2 Management
vLLM-0.9.2的软件版本管理及脚本程序管理
## 当前版本信息
1. 最新镜像
docker pull image.sourcefind.cn:5000/dcu/admin/base/vllm:0.9.2-ubuntu22.04-dtk25.04.1-rc5-rocblas104381-0915-das1.6-py3.10-20250916-rc2-ds3.2
该镜像默认使用V1 Engine，并且默认开启了Prefix Caching功能
2. 推荐使用的环境变量（可作为测试参考）
```
# 表示在并发数小于阈值时执行cudagraph模式，大于阈值时执行eager模式（产品建议K100AI设置成44，BW1000不设置该参数）
export VLLM_ENFORCE_EAGER_BS_THRESHOLD=44
# vllm 0.8.5/0.9.2版本出现精度乱码问题，可以尝试该环境变量解决
export VLLM_USE_FLASH_ATTN_PA=0
```
2. 常见模型部署方法
参考智算产品部提供的部署手册（定期更新）：https://r0ddbu55vzx.feishu.cn/docx/LL7KdYsWeoch7PxaS7wcBR5OnLe?from=from_copylink
3. 常见模型性能摸测结果
【金山文档 | WPS云文档】 大模型推理性能记录表_2025 https://www.kdocs.cn/l/cpcfyAiQx4WW（by 徐晓欧/刘煦/孙中谦）
4. 通用小参数量的大模型推荐的w8a8精度的量化方法是compressed-tensors、quark、w8a8-dynamic？（by 王凯雄）
DCU推荐使用: compressed-tensors
compressed-tensors 量化方法见链接: https://sw4sldkryl8.feishu.cn/docx/RJqldrez2o477Cxyo40cg3Ven7h?from=from_copylink
w8a8-dynamic 是华为卡上模型量化后的格式

离线环境安装包
api server测试方法需要jq和netcat依赖包，在离线环境内需要自行安装
jq_depends.zip和netcat_depends.zip是deb包，在ubuntu环境下可以直接安装
```
unzip jq_depends.zip
unzip netcat_depends.zip
dpkg -i *.deb
```
jq-1.5.tar.gz和netcat-0.7.1.tar.gz是源码，可以直接源码编译

<details>
<summary><b>🚀 Example - Online Benchmark</b></summary>
<br/>
First start serving your model
```bash
vllm serve NousResearch/Hermes-3-Llama-3.1-8B --disable-log-requests
```
Then run the benchmarking script
```bash
# download dataset
# wget https://huggingface.co/datasets/anon8231489123/ShareGPT_Vicuna_unfiltered/resolve/main/ShareGPT_V3_unfiltered_cleaned_split.json
python3 vllm/benchmarks/benchmark_serving.py \
--backend vllm \
--model NousResearch/Hermes-3-Llama-3.1-8B \
--endpoint /v1/completions \
--dataset-name sharegpt \
--dataset-path <your data path>/ShareGPT_V3_unfiltered_cleaned_split.json \
--num-prompts 10
```
If successful, you will see the following output
```

P99 ITL (ms): 8.39
==================================================
```
**Custom Dataset**
If the dataset you want to benchmark is not supported yet in vLLM, even then you can benchmark on it using `CustomDataset`. Your data needs to be in `.jsonl` format and needs to have "prompt" field per entry, e.g., data.jsonl
```
{"prompt": "What is the capital of India?"}
{"prompt": "What is the capital of Iran?"}
{"prompt": "What is the capital of China?"}
```
```bash
# start server
VLLM_USE_V1=1 vllm serve meta-llama/Llama-3.1-8B-Instruct --disable-log-requests
```
```bash
# run benchmarking script
python3 benchmarks/benchmark_serving.py --port 9001 --save-result --save-detailed \
--backend vllm \
--model meta-llama/Llama-3.1-8B-Instruct \
--endpoint /v1/completions \
--dataset-name custom \
--dataset-path <path-to-your-data-jsonl> \
--custom-skip-chat-template \
--num-prompts 80 \
--max-concurrency 1 \
--temperature=0.3 \
--top-p=0.75 \
--result-dir "./log/"
```
You can skip applying chat template if your data already has it by using `--custom-skip-chat-template`.
**VisionArena Benchmark for Vision Language Models**
```bash
# need a model with vision capability here
vllm serve Qwen/Qwen2-VL-7B-Instruct --disable-log-requests
```
```bash
python3 vllm/benchmarks/benchmark_serving.py \
--backend openai-chat \
--model Qwen/Qwen2-VL-7B-Instruct \
--endpoint /v1/chat/completions \
--dataset-name hf \
--dataset-path lmarena-ai/VisionArena-Chat \
--hf-split train \
--num-prompts 1000
```
**InstructCoder Benchmark with Speculative Decoding**
``` bash
VLLM_USE_V1=1 vllm serve meta-llama/Meta-Llama-3-8B-Instruct \
--speculative-config $'{"method": "ngram",
"num_speculative_tokens": 5, "prompt_lookup_max": 5,
"prompt_lookup_min": 2}'
```
``` bash
python3 benchmarks/benchmark_serving.py \
--model meta-llama/Meta-Llama-3-8B-Instruct \
--dataset-name hf \
--dataset-path likaixin/InstructCoder \
--num-prompts 2048
```
**Other HuggingFaceDataset Examples**
```bash
vllm serve Qwen/Qwen2-VL-7B-Instruct --disable-log-requests
```
**`lmms-lab/LLaVA-OneVision-Data`**
```bash
python3 vllm/benchmarks/benchmark_serving.py \
--backend openai-chat \
--model Qwen/Qwen2-VL-7B-Instruct \

--model Qwen/QwQ-32B \
--dataset-name hf \
--dataset-path philschmid/mt-bench \
--num-prompts 80
```
**Running With Sampling Parameters**
When using OpenAI-compatible backends such as `vllm`, optional sampling
parameters can be specified. Example client command:
```bash
python3 vllm/benchmarks/benchmark_serving.py \
--backend vllm \
--model NousResearch/Hermes-3-Llama-3.1-8B \
--endpoint /v1/completions \
--dataset-name sharegpt \
--dataset-path <your data path>/ShareGPT_V3_unfiltered_cleaned_split.json \
--top-k 10 \
--top-p 0.9 \
--temperature 0.5 \
--num-prompts 10
```
**Running With Ramp-Up Request Rate**
The benchmark tool also supports ramping up the request rate over the
duration of the benchmark run. This can be useful for stress testing the
server or finding the maximum throughput that it can handle, given some latency budget.
Two ramp-up strategies are supported:
- `linear`: Increases the request rate linearly from a start value to an end value.
- `exponential`: Increases the request rate exponentially.
The following arguments can be used to control the ramp-up:
- `--ramp-up-strategy`: The ramp-up strategy to use (`linear` or `exponential`).
- `--ramp-up-start-rps`: The request rate at the beginning of the benchmark.
- `--ramp-up-end-rps`: The request rate at the end of the benchmark.

# This script aims to tune the best server parameter combinations to maximize throughput for given requirement.
# The current server parameter combination is max_num_seqs and max_num_batched_tokens
# It also supports additional requirement: e2e latency and prefix cache.
# Pre-requisite:
# 1. Checkout to your branch, install/ update the correct running env. For TPU, activate conda env and install the corresponding torch, xla version.
# 2. If the model is customized, replace the MODEL's config with the customized config.
# 3. Set variables (ALL REQUIRED)
# BASE: your directory for vllm repo
# MODEL: the model served by vllm
# SYSTEM: the hardware, choice TPU or GPU, for other systems, "get best profile" might not support.
# TP: ways of tensor parallelism
# DOWNLOAD_DIR: directory to download and load model weights.
# INPUT_LEN: request input len
# OUTPUT_LEN: request output len
# MIN_CACHE_HIT_PCT: prefix cache rate
# MAX_LATENCY_ALLOWED_MS: (e2e) latency requirement. If there's no latency requirement, set it to a large number like 1000000000
# NUM_SEQS_LIST: a list of `max-num-seqs` you want to loop with.
# NUM_BATCHED_TOKENS_LIST: a list of `max-num-batched-tokens` you want to loop with.
# Note that the default NUM_SEQS_LIST and NUM_BATCHED_TOKENS_LIST are set for medium size input/output len, for extra short context (such as 20:20), you might need to include larger numbers in NUM_SEQS_LIST.
# 4. Run the script, it might take a long time, you can use tmux to avoid the script stop if disconnection happens.
# 5. The final result will be saved in RESULT file.
# Example use cases
# 1. Given input_len=1800, output_len=20, what's the best max_num_seqs and max_num_batched_tokens to get highest throughput?
# Use INPUT_LEN=1800, OUTPUT_LEN=20, MIN_CACHE_HIT_PCT=0, MAX_LATENCY_ALLOWED_MS=100000000000
# 2. If we have latency requirement to be lower than 500ms, what's the best server parameter?
# Use INPUT_LEN=1800, OUTPUT_LEN=20, MIN_CACHE_HIT_PCT=0, MAX_LATENCY_ALLOWED_MS=500
# 3. If we want to reach 60% prefix cache, what's the best server parameter?
# Use INPUT_LEN=1800, OUTPUT_LEN=20, MIN_CACHE_HIT_PCT=60, MAX_LATENCY_ALLOWED_MS=500

Benchmark the efficiency of prefix caching.
This script allows you to benchmark the performance of
a model with and without prefix caching using either fixed prompts
or prompts sampled from the ShareGPT dataset.
Fixed example usage:
python benchmark_prefix_caching.py \
--model meta-llama/Llama-2-7b-chat-hf \
--enable-prefix-caching \
--num-prompts 1 \
--repeat-count 100 \
--input-length-range 128:256
ShareGPT example usage:
# This command samples 20 prompts with input lengths
# between 128 and 256 tokens from the ShareGPT dataset,
# then replicates each prompt 5 times.
python benchmark_prefix_caching.py \
--model meta-llama/Llama-2-7b-chat-hf \
--dataset-path /path/to/ShareGPT_V3_unfiltered_cleaned_split.json \
--enable-prefix-caching \
--num-prompts 20 \
--repeat-count 5 \
--input-length-range 128:256
