为什么寒武纪的dp cambricon-device-plugin是用的原生的,但昇腾、NV的dp是HAMI自己写的?昇腾、NV原生的DP不适配吗,什么原因?

我们的调度 GPU 资源的前提,首先就是 scheduler 可以从 Node 上可以解码出对应卡的相关信息,即 dp 能够注册上 scheduler 需要的数据:
总之需要相关的信息,如果官方的 dp 无法提供 sched 需要的信息,我们就需要自己实现这个 dp,昇腾官方的 dp 是每种卡都需要对应的 dp
于是我们把昇腾的各种卡类型,对应的卡模版给抽象出来了,自己实现通过一个 dp 来处理不同卡不同模版的情况,方便与 sched 进行协同
NVIDIA 那就更是因为我们需要实现更多高级的特性(如算力显存限制,超配,NUMA 感知等),就需要更多信息了
Sorry, something went wrong.
感谢答疑
