> GPU topology affects performance dramatically. There's been a discussion in YARN-7481. But we'd like to move related discussions here.
> Please note that YARN-8851 will provide a pluggable device framework which has a shared scheduler which could support default topology scheduling. And Based on the framework, GPU plugin could have custom scheduler too.
