Zhankun Tang updated YARN-8821:
-------------------------------
Description:
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 can
support plugin custom scheduler. And based on the framework, GPU plugin could
have own topology scheduler.

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.
