Xiao Liang commented on YARN-8168:
----------------------------------
Thanks [~elgoiri], yes it should link to the NUMA work for Linux, and similar
implementation would be added in some way for Windows I think.
> Add support in Winutils for reporting CPU cores in all CPU groups, and
> aggregate kernel time, idle time and user time for all CPU groups

> Currently winutils can only report the CPU cores of the CPU group that it's
> running in, and the cpuTimeMs calculated from kernel time, idle time and user
> time is also for that CPU group only, which is not complete and incorrect for
> systems with multiple CPU groups (NUMA system for example).
