Process Scheduling Simulator

Optimize Your Process Management

Welcome to the Process Scheduling Simulator

Our simulator helps you understand and visualize different process scheduling algorithms, allowing you to optimize resource utilization and improve system performance.

FCFS Scheduling

Feature 1

First-Come First-Served (FCFS) Scheduling is one of the simplest CPU scheduling algorithms. In FCFS scheduling, processes are executed in the order they arrive in the ready queue. The process that arrives first gets executed first, hence the name "First-Come First-Served."

Simulate First-Come First-Served scheduling algorithm to understand its behavior.

SRT Scheduling

Feature 2

Shortest Remaining Time (SRT) Scheduling is a preemptive CPU scheduling algorithm that selects the process with the shortest remaining burst time to execute next. Unlike FCFS, which always executes the first arrived process, SRT continuously compares the remaining burst times of all processes and selects the one with the shortest remaining time to execute next. If a new process arrives with a shorter burst time than the currently executing process, the current process is preempted, and the new process is executed.

Experience Shortest Remaining Time scheduling algorithm with preemption for efficient process execution.

RR Scheduling

Feature 3

Round-Robin (RR) Scheduling is a preemptive CPU scheduling algorithm that allocates CPU time to each process in equal-sized time slices, typically referred to as time quantum or time slice. When a process's time quantum expires, it's preempted, and the CPU is allocated to the next process in the ready queue. If a process has more work to do, it's placed back in the queue to await its turn again. This cycle continues until all processes complete their execution.

How It Works

Our simulator operates by simulating the execution of multiple processes on a CPU using the Shortest Remaining Time (SRT) scheduling algorithm. Here's a breakdown of its operation:

  1. Input Gathering: The simulator collects input from the user, including the number of processes, their arrival times, and burst times. These parameters are crucial for accurately simulating the scheduling algorithm.

  2. SRT Algorithm Execution: Once the input is gathered, the simulator implements the Shortest Remaining Time (SRT) scheduling algorithm. This algorithm selects the process with the shortest remaining burst time to execute next. If a new process arrives with a shorter burst time than the currently running process, it preempts the current process and starts executing the new one.

  3. Time Quantum Handling: Unlike traditional Round-Robin scheduling, SRT dynamically adjusts the time quantum based on the remaining burst times of the processes. This ensures that shorter processes are given priority, potentially leading to lower average turnaround and waiting times.

  4. Process Execution and Tracking: The simulator tracks the execution of each process, updating completion times, turnaround times, and waiting times as the simulation progresses. It also calculates the total turnaround time and total waiting time for all processes.

  5. Result Presentation: Once the simulation completes, the simulator presents the results to the user. This includes detailed information such as completion times, turnaround times, waiting times for each process, as well as the average turnaround time and average waiting time across all processes.

  6. Visualization: Additionally, the simulator provides a visual representation of the scheduling using a Gantt chart. This chart displays the timeline of process execution, highlighting the start and end times of each process along with their respective quantum usage.
