Open the src folder with your Java IDE and run the "Main.java" file
Simulate the following process of the kernel of an O.S :
- Dispatching, scheduling transitioning
- Dispatching following a round robin technique and priority
- Change the status of the process accordingly
- All processes are arrived at time 0, before being fed into the system.
- The OS is fairly simple: It will not deal with I/O process that require user interaction, time delay. Thus, no I/O process will appear in the system. The provided process is simple, it just prints out some text.
- The system in question 1 only demonstrate a simple interacting flow between components of the operating system depends on the methods (Round Robin or Priority Queue).
In 4 classes: OperatingSystem.java, ProcessWareHouse.java, Scheduler.java, Dispatcher.java, they have the start() method that will be called to do that component specific missions (storing, scheduling, picking process). The CPU.java has the toExecute() method that execute the given process.
There are 4 main components in this stimulation namely ProcessWareHouse (in ProcessWareHouse.java – similar term used: PWH), Scheduler (in Scheduler.java), Dispatcher (in Dispatcher.java) and CPU (in CPU.java). They interact in Operating System class (in OperatingSystem.java). Each has different purposes and interleave with each other.
