Stellar simulator

This repository contains the final project of the subject Operating Systems of the Escuela Politécnica from the Universidad Autónoma de Madrid.

Description

The simulator process is the main process which is responsible to manage shared resources and coordinate the components in the simulation. Indeed, he establishes the arrival of a new turn. It will generate a leader process for each team. They will be responsible to coordinate and manage their spaceships. Each spaceship will be a child process of the leader process and they execute commands sent by the leader process within each shift.

The monitor process show the development of the simulation and has to be executed in another terminal.

The interprocess communication used are:

• simulator -> leaders : pipes
• leaders -> spaceships: pipes
• spaceships -> simulator: message queue
• state and map: shared memory
• turn: alarm

Requirements

• Make
• Ncurses

  sudo apt install libncurses-dev

Play It!

make
cd build
# First terminal
./simulator
# Second terminal
./monitor

Note: If you don't launch first the simulator you will get an error saying that one semaphore was not able to be opened. So, you always have to launch the simulator program first.
