“ShareGPT dataset”是一个包含500个提示的数据集,用于测试模型的性能。“TPS”(Tokens Per Second)是每秒处理的标记数,TPOT(Time Per Output Token)是每个输出标记所需的时间。 作者在一个月前发布了性能路线图,承诺将性能作为首要任务。现在他们发布了vLLM v0.6.0,相比之前的版本,吞吐量提升了1.8到2.7倍,同...
这里有个例子,2xH100,14~15 tokens/s。 在a100 x8 上(小吐槽,slurm 上装东西装出阴影了,反正最终是搞定了。如突出问题) 24 层在 GPU (对齐一下 a6000 的实验),2.83 tokens per second,比 a6000 慢,可能是 cpu 性能问题,没有深究。 全部在 8x GPU: 8.45 tokens per second 只用6x GPU: 8.33 tokens p...
Also, can we make sure there is no python overhead when sending async calls and also that there's is a large enough max batch size / number of tokens per batch set for vLLM? Sorry, something went wrong. Copy link Author joehoovercommentedDec 13, 2023 ...

I have trouble reading the screenshots you shared; can you share throughput (tokens per second) with both TGI and vLLM at a fixed QPS? it should include with and without speculation as well (without speculation may be faster in both cases). ...
为了优化 TPOT(Token Processing Over Time)和 TTFT(Time To First Token)性能,可以使用 vLLM 的分块预填充功能(--enable-chunked-prefill)。根据实验结果,推荐的批处理大小为 256(--max-num-batched-tokens=256)。 最后,让我们来看看 vLLM 使用 OpenVINO 后端运行大语言模型推理的效果,运行命令如下: ...
llama.cpp是本地编译的,编译的时候使⽤Intel oneAPI可以有效提升它的性能。英特尔尝试⽤了oneAPI⾥的Intel C++编译器和数学加速库MKL,结合jemalloc内存管理优化,推理速度可以达到每秒9.7~10词元 (TPS, tokens per second)。 上⾯的实验是在单路CPU上进⾏的,我们⼜在两路CPU上各⾃独⽴启动1个模型实例,...
rms核函数按照不同的token数划分,所以一共有num_tokens个block,每个block内开多个线程去执行rms算子。 template<typenamescalar_t> __global__voidrms_norm_kernel( scalar_t* __restrict__ out,// [num_tokens, hidden_size] constscalar_t* __restrict__ input,// [num_tokens, hidden_size] ...
