建议CPU选至强四代以上。

你现在觉得性能发挥不出来,感觉是什么瓶颈?

CPU 是两个8168, 目前感觉是带宽,感觉8卡并行不太行,跟4卡差不多速度

CPU有点老,17年的,参考链接:https://www.intel.com/content/www/us/en/products/sku/120504/intel-xeon-platinum-8168-processor-33m-cache-2-70-ghz/specifications.html

这个CPU的能力带八卡训练应该有点难。

另外这个CPU也只有PCIE3.0,通信应该也是有瓶颈的。主板也得考虑升级一下。

可以根据这个机箱配置新的机器:https://servers.asus.com.cn/products/Servers/GPU-Servers/ESC8000-E11P/

  • CPU支持4代和5代至强
  • 支持八张双槽显卡
  • 内部有PCIE交换,八卡都可以达到 PCIE5.0 x16的速度
  • 前面支持插8个NVME硬盘
  • 万兆电口
