当然我们也可以做个优化,让每个 GPU 在 pipeline parallelism 中处理的 80 组梯度数据首先在内部做个聚合,这样理论上一个 training step 就需要 48 秒,通信占用的时间不到 1 秒,通信开销就可以接受了。当然,通信占用时间不到 1 秒的前提是机器上插了足够多的网卡,能够把 PCIe Gen4 的带宽都通过网络吐出去,否...
The Belt and Road Initiative draws investment from diverse sources, encourages third-party market cooperation, and aims to build industry, supply, service, and value chains that benefit all and are shared by all, so as to provide new growth drivers for faster development in the participating coun...
And our decade-long mission is to bring one million women into mobility and be the largest network of women drivers connected to each other. 道路已准备就绪,迫不及待。我们长达十年的使命是让100万女性进入机动领域,成为相互联系的最大女性司机网络。 By rethinking mobility for women, giving them a ...
这是一个好问题。先说结论,大模型的训练用 4090 是不行的,但推理(inference/serving)用 4090 不仅可行,在性价比上还能比 H100 稍高。4090 如果极致优化,性价比甚至可以达到 H100 的 2 倍。 事实上,H100/A100 和 4090 最大的区别就在通信和内存上,算力差距不大。
