What is multiprocessor scheduling explain with example?
Multiple processor scheduling or multiprocessor scheduling focuses on designing the scheduling function for the system which is consist of ‘more than one processor’. With multiple processors in the system, the load sharing becomes feasible but it makes scheduling more complex.
What is multiprocessor scheduling in operating system?
Multiple processor scheduling or multiprocessor scheduling focuses on designing the system’s scheduling function, which consists of more than one processor. Multiple CPUs share the load (load sharing) in multiprocessor scheduling so that various processes run simultaneously.
What are 4 major scheduling algorithms?
Operating System Scheduling algorithms
- First-Come, First-Served (FCFS) Scheduling.
- Shortest-Job-Next (SJN) Scheduling.
- Priority Scheduling.
- Shortest Remaining Time.
- Round Robin(RR) Scheduling.
- Multiple-Level Queues Scheduling.
What are two types of scheduling algorithms?
Six types of process scheduling algorithms are: First Come First Serve (FCFS), 2) Shortest-Job-First (SJF) Scheduling, 3) Shortest Remaining Time, 4) Priority Scheduling, 5) Round Robin Scheduling, 6) Multilevel Queue Scheduling.
What are the main features of multiprocessor scheduling?
In the multiprocessor scheduling, there are many processors and they are identical and we can run any process at any time. The multiple CPU’s in the system are in the close communication which shares a common bus, memory and other peripheral devices….3. Symmetric multiprocessor
- Locking system.
- Shared data.
- Cache coherence.
What are the CPU scheduling algorithms?
Types of CPU Scheduling algorithms
- First Come First Serve.
- Shortest Job First.
- Shortest Remaining Time First.
- Round Robin Scheduling.
- Priority Scheduling.
- Multilevel Queue Scheduling.
- Multilevel Feedback Queue Scheduling.
Which scheduling algorithm is best?
Sometimes FCFS algorithm is better than the other in short burst time while Round Robin is better for multiple processes in every single time. However, it cannot be predicted what process will come after. Average Waiting Time is a standard measure for giving credit to the scheduling algorithm.
Which data structure is used for multiprocessor scheduling?
This approach uses Symmetric Multiprocessing where each processor is self-scheduling. The scheduling proceeds further by having the scheduler for each processor examine the ready queue and select a process to execute.
Where are multiprocessor systems used?
Multiprocessor systems are being used successfully today to improve performance in systems running multiple programs concurrently. In addition, multiprocessor systems have shown the ability to improve single-program performance significantly for certain applications containing easily parallelized loops.
