Scheduling algorithms play a pivotal role in determining the order and efficiency of processes in computational systems. With growing digital transformation, there’s a rising need for tools that simplify these complex calculations. Enter the Scheduling Algorithm Calculator – a device meticulously designed to tackle such computations head-on, ensuring users get the results they require without the hassle.
Definition
A Scheduling Algorithm Calculator is a computational tool designed to determine the average waiting time for different processes based on established scheduling algorithms. This calculator evaluates metrics like total waiting time, total burst time, and quantum time to derive essential outcomes, offering users clarity in decision-making.
Detailed explanations of the calculator’s working
Our calculator, rooted in intricate coding, evaluates user-provided metrics based on the chosen scheduling algorithm. Users can select from First-Come, First-Served (FCFS), Shortest Job Next (SJN) / Shortest Job First (SJF), or Round Robin (RR). Once input fields are populated, the calculator seamlessly computes the average waiting time, providing a clear, accurate result.
Formula with variables description
When diving into the scheduling algorithms and their formulas:
- First-Come, First-Served (FCFS):
- Average Waiting Time = (Total Waiting Time for all processes) / (Number of processes)
- Shortest Job Next (SJN) / Shortest Job First (SJF):
- Average Waiting Time = (Total Waiting Time for all processes) / (Number of processes)
- Note: SJN/SJF aims to minimize the total execution time.
- Round Robin (RR):
- Average Waiting Time = [(n – 1) * Quantum Time + Total Burst Time of all processes] / (n * Number of processes)
- Note: RR allocates a fixed time quantum to each process in a cyclic manner.
Example
Consider a scenario where we’re assessing three processes in the RR algorithm. Given:
- Total Waiting Time: 15 units
- Total Burst Time: 20 units
- Quantum Time: 3 units
- Number of Processes: 3 The calculator evaluates to produce an average waiting time based on the RR formula, simplifying user computations.
