Sep 6, 2024 · Practice example problems of CPU scheduling algorithms like FCFS, SJF, Round Robin, SRTF, and Priority Scheduling with Gantt Chart.

Practice Problems on CPU Scheduling Algorithms. Various CPU Scheduling Algorithms are- FCFS Scheduling, SJF Scheduling, SRTF Scheduling, Round Robin Scheduling, Priority Scheduling.

There is an algorithm that optimally solves the problem with time complexity O((n ⋅log(max p j))k) for some fixed k. NP-hard in the ordinary sense (pseudo polynomial time complexity): The problem cannot be optimally solved by an algorithm with polynomial time complexity but with an algorithm of time complexity O((n ⋅max p j)k).

Apr 4, 2025 · CPU scheduling is a process used by the operating system to decide which task or process gets to use the CPU at a particular time. This is important because a CPU can only handle one task at a time, but there are usually many tasks that need to be processed. The following are different purposes of a CPU scheduling time.

The document contains sample problems and their solutions for different CPU scheduling algorithms including FCFS, SJF, Round Robin, and Priority scheduling. For each algorithm, multiple problems are presented with the arrival times and burst times of processes.

Draw four Gantt charts that illustrate the execution of these pro-cesses using the following scheduling algorithms: FCFS, SJF, non-preemptive priority (a larger priority number implies a higher priority), and RR (quantum = 2). b. What is the turnaround time of each process for each of the scheduling algorithms in part a? c.

Urban legend about IBM 7074 at MIT: when shut down in 1973, low-priority processes were found which had been submitted in 1967 and had not yet been run... This is the biggest problem with static priority systems: a low priority process is not guaranteed to run — ever!

Issues with this approach? How do you choose time slice? A (100ms CPU), B (100ms CPU), C (1ms CPU + 10ms I/O), ... What do we learn from this example? T1 tries to acquire L, fails, blocks. T3 enters system at priority 3. What does this method do? ... Is this a good idea?

Here are 30 questions on RR (Round Robin) process scheduling algorithms . Each question is presented in a table format, followed by the solution with Gantt charts, average turnaround time (TAT), and average waiting time (WT).

We have covered the following aperiodic task scheduling algorithms: –Largest Processing Time Algorithm (no precedence constraints, no preemption) –Priority List Scheduling Algorithm (with precedence constraints, no preemption) –Decreasing Priority List Scheduling Algorithm (with precedence constraints, no preemption, LPT rule for priority)
