"Consider a system running five I/O-bound tasks and 2 CPU-bound tasks. Assume that the I/O-bound tasks issue an I/O operation once for every millisecond of CPU computing and that each I/O operation takes 10 milliseconds to complete. Also assume that the contextswitching overhead is 0.2 millisecond and that all processes are long-running tasks. Remember that when a process requests for I/O operations, it will suspend and another process will need to be selected for execution. What is the CPU utilization for a round-robin scheduler when:
a. The time quantum is 1 millisecond b. The time quantum is 10 milliseconds"
Construct a resource allocation graph with the following processers and resources, the system consists of four processers P1, P2, P3, and P4 and five resources R1, R2, R3, R4, and R5.
Write a bash shell script filestatic. The script should examine the number files in directories given as arguments (parameters) to this script.
Suppose an operating system maps user-level threads to the kernel using the many-to-many model and the mapping is done through LWPs.
Explain a complication that concurrent processing adds to an operating system.
Remembering that there's a trade-off between memory use. Then give an example where doing so will cause throughput to suffer.
How many page faults would occur under pure demand paging (all frames are initially empty), assuming four frames are available, under FIFO, LRU.
Other user user threads belonging to the same process also be affected by the page fault (i.e., would they also have to wait for the faulting page to be brought into memory?) Explain.
Describe three solutions to critical section problem Explain the different methods used to handle deadlocks Distinguish between "No preemption" and "circular wait" in deadlocks prevention
