Select all statements that are true. With the Completely Fair Scheduler, the task with the smallest value of vruntime is considered to have the highest priority. With fine-grained multithreading, a thread executes on a core until a long-latency event such as a memory stall occurs. Pull migration occurs when an idle processor pulls a waiting task from a busy processor. The Completely Fair Scheduler assigns a proportion of CPU processing time to each task. Load balancing is typically unnecessary on systems where each processor has its own private ready queue of eligible threads to execute. Systems using the one-to-one model schedule kernel-level threads using process contention scope. Interrupt latency refers to the period of time from the arrival of an interrupt at the CPU to the start of the routine that services the interrupt. In asymmetric multiprocessing, each processor is self-scheduling. | Balancing loads by moving a thread from one processor to another may counteract the benefits of processor affinity
