Three projects made for the course "Distributed and Concurrent Programming" (MSc, Computer Science @Unibo). The focus of these projects is about concurrency, so other aspects of software development (Testing, code quality, OOP principles, etc..) were left out.

1st Assignment

Professor Ricci gave us a program which simulate the behaviour of N bodies inside a field. These bodies are moving because of the repulsive force between them. The program needs to do a lot of computation, so the simulation is slow. Our goal is to provide a solution to speed-up the simulation using different threads. For more information you can check the assignment report (only available in italian).

2nd Assignment

This assignment is divided in three points:

• Implement a task-based version of the first assignment.
• Event-driven Asynchronous Programming.
• Reactive Programming.

3rd Assignment

Implement an application to monitor rain level in a city. The city is divided in a NxM grid: in each zone there are multiple sensors and an Emergency Station. Each sensor monitor the rain level: if it exceed a treshold the sensor change its state to 'Alarm'. if the majority of sensors in a zone are in alarm, the local Emergency station will be notified. A sensor can also randomly fail. Once the emergency is handled by the station, the zone return in a normal state.

The application is developed using Akka and Scala.
