LLM 查找表针对慢速存储进行优化,减少内存使用

研究人员开发了一种方法,通过利用按层预取截止时间来优化像 DeepSeek-V4.1 这样的 LLM 的大型查找表的放置。这种方法允许将表存储在 NVMe 等慢速存储或远程内存上,在不显著影响性能的情况下大大减少主机内存需求。研究表明,通过智能管理读取时间和利用会话重用等技术,可以大幅削减内存使用量,为 KV 缓存等其他关键功能释放资源,从而提高吞吐量并降低延迟。 AI

影响 能够显著减少 LLM 服务的内存占用,可能降低硬件成本并提高部署可行性。

    按层预取截止时间放置 LLM 查找表

    arXiv:2611.13413v1 Announce Type: cross Abstract: DeepSeek-V4.1's 203 GB of Engram n-gram tables sit in host DRAM today, taking 190 of the 223 GiB a 4-GPU serving process uses. Row indices depend only on input tokens, so reads can start with each step and overlap earlier layers. …
