Question 8 (1 point) Non-Uniform Memory Access (NUMA) is a computer memory design used in multiprocessing, where the memory access time depends on the memory location relative to the processor. Under NUMA, a processor can access its own local memory faster than non-local memory (memory local to another processor or memory shared between processors). The benefits of NUMA are limited to particular workloads, notably on servers where the data is often associated strongly with certain tasks or users. True False Question 14 (1 point) With the Linux CFS Scheduler, each task is assigned a proportion of CPU processing time. True False Question 15 (1 point) With the Linux CFS scheduler, the scheduler directly assigns priorities. True False Question 16 (2 points) A CPU-scheduling algorithm determines an order for the execution of its scheduled processes. Given n processes to be scheduled on one processor, n^2 different schedules are possible. True False Question 20 (1 point) Process Contention Scope (PCS) scheduling is local to the process. It is how the thread library schedules threads onto available light weight processes. True False Question 21 (1 point) System Contention Scope (SCS) scheduling is used when the operating system schedules kernel threads. True False Question 22 (1 point) On systems using either the many-to-one or the many-to-many model, PCS and SCS are fundamentally different. On systems using the one-to-one model, PCS and SCS are the same. True False Question 25 (1 point) Saved Heterogeneous multiprocessing (HMP) could be very useful in a mobile system. True False
