# 0.8.5
1. Offline推理 根据需求自定义参数
benchmark_throughput_0.8.5.py
使用如下脚本可以减少不同参数推理时反复load模型
batch prompt_tokens completion_tokens可以用空格分隔传成字符串
其他参数与标准脚本一致
<pre>
export HIP_VISIBLE_DEVICES=1
tp=1
model_path=/llm-models/qwen1.5/Qwen1.5-0.5B-Chat

batch="1 2"
prompt_tokens="16 64"
completion_tokens="128 256"
python benchmark_throughput_0.8.5.py --model ${model_path} --tensor-parallel-size ${tp} --num-prompts ${batch} --input-len ${prompt_tokens} --output-len ${completion_tokens} \
    --dtype float16  --trust-remote-code --max-model-len 32768 --output-json ./test_0.5B-0.7.2.txt
</pre>

按照如上传参，则计算的场景如下：
bs    input    output
1      16        128
1      64        256
2      16        128
2      64        256

推理结果汇总在--output-json ./test_0.5B-0.7.2.txt当中,示例如下：

bash
bs_in_out,elapsed_time,Throughput,total_tokens,output_tokens,ttft_mean,ttft_median,ttft_p99,tpop_mean,tpop_median,tpop_p99,output_token_throughput_mean,output_token_throughput_median,output_token_throughput_p99,inout_token_throughput_mean,inout_token_throughput_median,inout_token_throughput_p99

2. Server推理
先 bash server.sh  等待服务起来后 再bash test.sh   根据需求修改测试参数

#发送请求
#--distributed-executor-backend ray等其他参数根据实际情况添加

python  benchmark_servein_0.7.2.py --backend vllm --ignore-eos  --dataset-name random --random-input-len  $input_len --random-output-len  $output_len --model $MODEL_PATH  --num-prompts $num_prompts --endpoint /v1/completions
</pre>

tp=1
model_path=/llm-models/qwen1.5/Qwen1.5-0.5B-Chat


batch="1 2"
prompt_tokens="16 64"
completion_tokens="128 256"
python benchmark_throughput_0.6.2.py --model ${model_path} --tensor-parallel-size ${tp} --num-prompts ${batch} --input-len ${prompt_tokens} --output-len ${completion_tokens} \
    --dtype float16  --trust-remote-code --max-model-len 32768 --output-json ./test_0.5B-0.6.2.txt
</pre>
按照如上传参，则计算的场景如下：

1      16        128
1      64        256
2      16        128
2      64        256

推理结果汇总在--output-json ./test_0.5B-0.6.2.txt当中,示例如下表：

bash
bs_in_out,elapsed_time,Throughput,total_tokens,output_tokens,ttft_mean,ttft_median,ttft_p99,tpop_mean,tpop_median,tpop_p99,output_token_throughput_mean,output_token_throughput_median,output_token_throughput_p99,inout_token_throughput_mean,inout_token_throughput_median,inout_token_throughput_p99

2. Server推理
benchmark_servein_0.6.2.py
backend_request_func.py
使用此方式可以减少server生成长度和指定长度差距过大
<pre>
#使用提供的脚本进行测试

#启动server
vllm serve $MODEL_PATH  --trust-remote-code   --dtype $dtype --max-model-len $max_len -tp $tp  --gpu-memory-utilization 0.97



#发送请求
#--distributed-executor-backend ray等其他参数根据实际情况添加
方式与平常一样，只是需要加上--ignore-eos
python  benchmark_servein_0.6.2.py --backend vllm --ignore-eos  --dataset-name random --random-input-len  $input_len --random-output-len  $output_len --model $MODEL_PATH  --num-prompts $num_prompts --endpoint /v1/completions
</pre>
