📙 About

  • A CPU scheduler determines an order for the execution of its scheduled processes; it decides which process will run according to a certain data structure that keeps track of the processes in the system and their status.
  • A process, upon creation, has one of the three states: Running, Ready, Blocked (doing I/O, using other resources than CPU or waiting on unavailable resource).

📃 System Description

  • Consider a Computer with 1-CPU and fixed size memory (1024 ==> can be changed). Our scheduler implemented the complementary components as sketched in the following diagrams.

📌 NOTE:

We are supporting the following Scheduling algorithms:

  1. HPF (Highest Priority First)
  2. STRN (Shortest Time Remaining Next)
  3. RR (Round Robin)

    For memory we are using the buddy memory allocation system.
