Pintos Project 1: Threads - Alarm Clock and Advanced Scheduler

Overview

This repository contains the implementation of Project 1 for the Software Infrastructure (IF677) course at CIn-UFPE. The project focuses on enhancing the Pintos operating system by implementing an alarm clock and an advanced scheduler for thread management.

Group Members

  • Alberto Guevara de Araújo Franca
  • Felipe Mateus Falcão Barreto
  • Felipe Torres de Macedo

Project Goals

  1. Alarm Clock:

    • Implement a mechanism to allow threads to wake up at specific times.
    • Ensure that threads are correctly unblocked when their alarm time expires.
    • Handle thread priority adjustments based on alarm time.

  2. Advanced Scheduler:

    • Enhance the default scheduler (round-robin) to support multiple priority levels.
    • Implement the Multi-Level Feedback Queue (MLFQ) scheduling algorithm.
    • Prioritize threads based on their recent CPU usage and execution history.

Tools Used

  • Git: Version control system for collaborative development.
  • Live Share: Collaborative real-time coding sessions.
  • Bochs(2.6.11) and QEMU: Simulators for testing and debugging Pintos.
