CPU interference: For the the purpose of this document, CPU interference is defined as any case where kernel management functions will take CPU time from a pure CPU bound user task making no system call and running pinned to an isolated CPU with no other contending user tasks. Specifically, any kernel activity that occurred as a result of the the specific task activity is not considered interference. However, kernel activity on the specific CPU happening as a result of work of other tasks or the general kernel infrastructure not related a specific task are considered interference.
