Analysis of Optimization of Multi Level Average Queue with Multi Dynamic Queue

Introduction

Scheduling is a vital component in the operating system that functions to regulate the Central Processing Unit (CPU) to determine which processes must be executed first. Without the right scheduling, the CPU cannot choose the process wisely, which can lead to deadlock or deadlocked conditions in compiling the order of processing data queues. This situation becomes more complicated considering the number of queuing data processes is very large, where the time allocation for execution is very limited. Therefore, efficiency in the use of execution time is strongly influenced by the speed of CPU in carrying out various processes.

The operating system has an important task to divide the CPU time allocation between various processes waiting to be executed. Good management of this scheduling is needed so that all processes in the queue can be served optimally, without being rejected or experienced a long delay. Prolonged delays can have a negative impact on the time allocated for each process.

To overcome challenges in managing the queue process, multi-dynamic queue scheduling algorithms can be used. This algorithm combines several scheduling approaches such as First-Comce, First-Served (FCFS), Shortest Job First (SJF), and Round Robin to deal with dynamic data queues, based on a predetermined waiting time. In the application of this algorithm, it is expected that the optimization value of the average waiting time can be obtained, so that the waiting time in the queue process can be more efficient and optimal.

Scheduling Algorithm Analysis

1. FCFS (First-Come, First-Served)

FCFS is a simple scheduling algorithm where the process that comes first will be executed first. Although easy to understand, the weakness of FCFS is that it can cause the problem "Convoy Effect", where small processes that come after a large process must wait a long time, so the overall waiting time becomes inefficient. This algorithm is not suitable for systems with a large number of processes, as it can lead to a significant increase in waiting time.

2. SJF (Shortest Job First)

SJF is a scheduling algorithm that prioritizes the process with the shortest execution time. This approach can reduce the average waiting time, but the difficulty in determining the duration of the process is a challenge. In addition, SJF can cause starvation for longer processes, which can lead to a significant decrease in system performance.

3. Round Robin

Round Robin is a scheduling algorithm that divides the CPU time fairly to all processes in the queue by giving each process of the same execution time slot. This method is very effective for an operating system that is interactive, because it provides a rapid response to each process, but can increase the waiting time if not managed properly. Round Robin is a good choice for systems with a large number of processes, as it can help to reduce the waiting time.

Optimization with Multi Dynamic Queue

The use of multi-dynamic queue algorithms optimizes the average waiting time by combining the advantages of each scheduling algorithm. More dynamic scheduling allows the CPU to adjust to the changing queue conditions, so as to minimize the waiting time. By implementing this algorithm, we can get more optimal results in managing the queue data process. Efficient scheduling not only improves CPU performance, but also provides better user experience, especially in systems that require fast response.

Benefits of Multi-Dynamic Queue

  1. Improved CPU Performance: Multi-dynamic queue algorithms can help to improve CPU performance by reducing the waiting time and increasing the throughput.
  2. Better User Experience: Efficient scheduling can provide a better user experience, especially in systems that require fast response.
  3. Optimized Resource Allocation: Multi-dynamic queue algorithms can help to optimize resource allocation by allocating the right amount of resources to each process.
  4. Reduced Waiting Time: Multi-dynamic queue algorithms can help to reduce the waiting time by prioritizing the process with the shortest execution time.

Conclusion

In conclusion, the use of multi-dynamic queue algorithms can help to optimize the average waiting time by combining the advantages of each scheduling algorithm. More dynamic scheduling allows the CPU to adjust to the changing queue conditions, so as to minimize the waiting time. By implementing this algorithm, we can get more optimal results in managing the queue data process. Efficient scheduling not only improves CPU performance, but also provides better user experience, especially in systems that require fast response.
