DeepSeek 开源日第 5 天:发布高性能并行文件系统 3FS,数据吞吐量高达 6.6 TiB/s

2025年2月28日,DeepSeek 在开源周的第五天发布了 3FS(Fire-Flyer File System),这是一个专为现代 SSD 和 RDMA 网络带宽设计的高性能并行文件系统。该系统在数据访问性能上表现出色,特别适用于深度学习等数据密集型应用。

3FS 在180节点集群中实现了6.6 TiB/s的聚合读取吞吐量,在25节点的GraySort基准测试中达到了3.66 TiB/min的吞吐量。每个客户端节点的KVCache查找峰值吞吐量超过40 GiB/s。3FS采用去中心化架构,提供强一致性语义。

该文件系统在DeepSeek V3 / R1版本中广泛应用,涵盖了数据预处理、数据集加载、检查点保存/加载等关键过程,同时DeepSeek还开源了基于3FS的处理框架Smallpond。

Stocks dropped on Friday afternoon, as gains made earlier in the day on hopes for diplomatic progress between Russia and Ukraine turned to losses. Technology stocks were hit particularly hard by higher bond yields. Either way, Durov says that he withdrew his resignation but that he was ousted from his company anyway. Subsequently, control of the company was reportedly handed to oligarchs Alisher Usmanov and Igor Sechin, both allegedly close associates of Russian leader Vladimir Putin. The fake Zelenskiy account reached 20,000 followers on Telegram before it was shut down, a remedial action that experts say is all too rare. The regulator said it has been undertaking several campaigns to educate the investors to be vigilant while taking investment decisions based on stock tips. The Dow Jones Industrial Average fell 230 points, or 0.7%. Meanwhile, the S&P 500 and the Nasdaq Composite dropped 1.3% and 2.2%, respectively. All three indexes began the day with gains before selling off.
