In first phase, TOPSIS algorithm is applied to obtain the relative closeness of tasks with respect to selected scheduling criteria (i.e., execution time, transmission time and cost). In second phase the particle swarm optimization (PSO) begins with computing relative closeness of the given three...
The process state of the executing process is saved in the process table and the higher priority process starts to execute. Another scenario is when a short process enters the system which uses Shortest Remaining Time Next scheduling algorithm. If a longer process is executing, it is pre-empted...
Key Difference - Preemptive vs Nonpreemptive Scheduling in OS A process is a program in execution. A computer should perform many tasks at the same time.

In this paper, we propose a tabu search algorithm for nonpreemptive scheduling of periodic real-time tasks in multiprocessor systems under precedence and resource constraints. The real-time tasks are characterized by their periods, deadlines, worst-case computation times and precedence and resources ...

Preemptive scheduling is a type of scheduling where the operating system can interrupt a running process and allocate the central processing unit (CPU) to another process. The operating system decides when to preempt a process based on predefined rules, such as priority levels or time quantum. In...
