# 废弃GPU变废为宝：DumpsterCluster用60美元显卡跑LLaMA-70B

arXiv新论文研究使用数据中心淘汰的二手GPU构建DumpsterCluster集群，成功运行LLaMA-70B大模型推理。随着AI数据中心大量退役尚可使用的GPU，这些设备进入二级市场，论文探索了它们是否能继续发挥价值。结果显示，通过合理的分布式策略，低价回收的GPU依然能支撑现代LLM推理服务，大幅降低推理成本。

## English Version

**DumpsterCluster: Serving LLaMA-70B on $60 Retired GPUs**

A new arXiv paper explores building a DumpsterCluster from retired datacenter GPUs to serve LLaMA-70B inference. As AI datacenters retire functional hardware, these accelerators flood secondary markets. The study shows that with proper distributed strategies, low-cost recycled GPUs can still power modern LLM inference, dramatically reducing serving costs.
