Round Robin Process Scheduler (Group 10)

The program is a simulator of a Round-Robin process scheduler written in C with a graphical user interface (GUI) using the IUP library.

Method 1: Directly run batch file (RUN_AND_SAVE.bat or RUN_ONLY.bat)

• To run the program, from the ./run folder, run RUN_AND_SAVE.bat or RUN_ONLY.bat. Input your data.
• RUN_AND_SAVE.bat will save the simulation output in two places: 1) ./run/analysis.txt and 2) a relevant timestamped file inside the ./run/log folder. The ./run/analysis.txt file will automatically open for review.
• RUN_ONLY.bat only prints the simulation output to the terminal.
• For both batch files, users are prompted in the terminal if they wish to start a new simulation. Press 'Y' to start a new simulation or 'N' to terminate the application.
• Please ensure that roundrobin.exe and iup.dll are in the same folder as the batch files. This should already be the structure of the ./run folder.

Method 2: Compile executable then run batch file (RUN_AND_SAVE.bat or RUN_ONLY.bat)

• For modularity and to facilitiate division of work, more than one c file is used.

2.1 Using command line (gcc)

• Please ensure that you are in the directory where the c files and the iuplib folder are located.
• Please ensure that the iuplib folder (containing the include directory with the iup.h file inside it) is in the same folder as the c files.
• Run the following commands:

// Compile each source file into an object file
gcc -Wall -g -Wextra -Iiuplib\include -Iiuplib -c .\queue.c -o .\queue.o
gcc -Wall -g -Wextra -Iiuplib\include -Iiuplib -c .\robinui.c -o .\robinui.o
gcc -Wall -g -Wextra -Iiuplib\include -Iiuplib -c .\roundrobin.c -o .\roundrobin.o

// Link the object files together to create the executable
gcc -Liuplib -o .\run\roundrobin.exe .\queue.o .\robinui.o .\roundrobin.o -lgdi32 -luser32 -lkernel32 -lcomctl32 .\iuplib\libiup.a

• To run the program, from the ./run folder, run RUN_AND_SAVE.bat or RUN_ONLY.bat. Input your data.
• RUN_AND_SAVE.bat will save the simulation output in two places: 1) ./run/analysis.txt and 2) a relevant timestamped file inside the ./run/log folder. The ./run/analysis.txt file will automatically open for review.
• RUN_ONLY.bat only prints the simulation output to the terminal.
• For both batch files, users are prompted in the terminal if they wish to start a new simulation. Press 'Y' to start a new simulation or 'N' to terminate the application.

2.2. Using Code::Blocks

• In Code::Blocks, import the directory and open the RoundRobin.cbp file.
• Build and run from within the IDE.
• Please ensure you have the iuplib folder, roundrobin.c and roundrobin.cbp file in the same folder (same structure as in the repository).
• The simulation output is only printed to the console.
