Linux kernel 5.14 adds the support for Core Scheduling. This allows setting and copying core scheduling 'task cookies' between the container process and the threads (PID), processes (TGID), and process groups (PGID), which helps define groups of tasks that can be co-scheduled on the same core. These groups can be specified either for security usecases or for performance usecases. opencontainers#1113 Signed-off-by: Kailun Qin <kailun.qin@intel.com>

There was a problem hiding this comment.
Did you mean thread groups?
