Plazza project:

  • Tools:
    • Project made in C++ version 20
    • Compiled with CMake, minimum version required : 3.6
    • a justfile is provided to compile it

The purpose of the project is to simulate a pizzeria, which is composed of two main parts:

- a Reception:
    - Takes and send orders to kitchens
    - Receives the finished order and gives it to the customer
    - Keeps a log of all orders made

- Kitchens containing:
    - a fridge with ingredients stocks
    - a set number of cooks, represented as a thread pool
  • Notions we had to implement and encapsulate:
    • Load balancing
    • processes synchronization & commmunication (IPC)
    • POSIX threads synchronization & commmunication

For further details about the implementation of these notions, you can click here to be redirected to our documentation.

Usage:

  • How to compile the project:

    • To build on debug mode : mkdir build && just debug

    • To build on release mode : mkdir build && just build

  • How to start the program:

    • ./plazza 2 5 4000

The first parameter is a multiplier for the cooking time of the pizzas.
-> If the value is between 0 and 1, kitchens will cook faster
-> Else it will cook slower

The second parameter is the number of cooks per kitchen. Each kitchen represents its cooks in a thread pool.

The third parameter is the time in milliseconds, used by the kitchen to replace ingredients.

Highlights:

  • C++ thread pool implementation : documentation

    • Generic creation and run of a thread pool.
    • You can choose the number of threads you want in your pool.

  • C++ process wrapper : documentation

    • This class is a wrapper to the unix fork and wait functions
    • It allows to create a new process and wait for its termination.

  • C++ named pipe wrapper : documentation

    • The NamedPipe class is a wrapper around the mkfifo and open system calls.
    • It allows to create a named pipe with two directions, one for reading and one for writing.

  • C++ class object serialization and deserialization : documentation

    • Send serialized datas during inter-process communication
    • Recovers the datas and recreates an instance of the class with the provided serialized datas
