<p dir="auto"><img src="https://upload.lcz.me/uploads/b49a7e37-de56-4722-831c-3a3aeafbcfee.jpeg" alt="image.jpeg" class="img-markdown  img-fluid" /></p>
<p dir="auto">啥也不说，先放PR:<a href="https://github.com/Niko1221/Strata/pull/260" rel="nofollow ugc">https://github.com/Niko1221/Strata/pull/260</a> 找个趁手的Agent帮你部署一下就好了。</p>
<p dir="auto">简单谈几个可能会被忽视的小细节：</p>
<ol>
<li>
<p dir="auto">这个引擎的专家基本都在RAM缓存，支持CPU/GPU混合计算，所以会看到一个奇怪现象：段上下文的pp/tg比长上下文的pp低，这主要是VRAM caching构建中的摩擦成本，所以这模型越用越快也是有点意思。刚开始随机跟它对话的话tg大概40左右，用dsh加一个9k的prompt居然tg到了50，考虑到这是个80GB+模型，这个引擎也算是agent圣体了。<br />
下面是一个dsh 120k session的 tg随context下降的图表：<br />

</li>
<li>
<p dir="auto">pp阶段主要瓶颈是pcie带宽，我本来是双卡7900xtx pcie4<em>8 拆分，把另一张卡关机拔了重启后主显卡自动获得pcie4</em>16，pp自动涨了+30%，tg也涨了10%。另外可以看到12GB 的5070 tg和24g的7900xtx一样，主要是因为人家是pcie5*16，估计未来R9700支持之后速度会更快，当然要搭配更贵的PCIE5主板和内存。</p>
</li>
</ol>
<p dir="auto">最后API server的拉起命令:</p>
<pre><code>cd path/to/Strata
HIP_VISIBLE_DEVICES=0 PYTHONUNBUFFERED=1 \
  ~/.config/strata/venv/bin/python -m serve.server \
    --engine strata --config /home/jianwei/.config/strata/serve.json --port 8080
