This program simulates and demonstrates how the algorithms of operating systems work.

To run this apllication you will need:

• .NET 4.0 Framework installed

To demonstrate the algorithms listed below do the followings:

• Download the released binaries and examples or download the source files then build the application
• Start the application and load some input files
• Run some simulations

1. Download the zip archive or clone this repository by using git command: git clone https://github.com/prokhyon/OS_Algorithm_Simulator.git
2. Open the OS_SIMULATOR.sln file (located in OS_Simulator folder in the repository) in Visual Studio 2013 or higher
3. Build the project
4. Start the application by pressing F5

0. Start the application (a main view will be visible)
1. Open one of the *.xml examples (located in inputs/examples or inputs/test folder in the repository) by pressing Load Simulation button
2. Select the opened simulation and open the simulation's view by pressing Open Simulation button
3. Run the simulation by pressing Next Step or Previous Step buttons

The following algorithms can be simulated and demonstrated by the program:

• Task Scheduler algorithms
  • First Come First Served (FCFS) / First Input First Output (FIFO)
  • Round Robin (RR)
  • Shortest Job First (SJF)
  • Shortest Remaining Time First (SRTF)
• Memory Allocation Algorithms
  • First Fit (FF)
  • Next Fit (NF)
  • Best Fit (BF)
  • Worst Fit (WF)
• Page Replacement Algorithms
  • Optimal (OPT)
  • First Input First output (FIFO)
  • Second Chance (SC)
  • Last Recently Used (LRU)
  • Least Frequently Used (LFU) / Not Frequently Used (NFU)
  • Not Recently Used (NRU)
• Virtual Address Mapping
