Question

I need help with a MINIX programming problem.

45. Modify the MINIX 3 scheduler to keep track of how much CPU time each user process
has had recently. When no task or server wants to run, pick the user process that has
had the smallest share of the CPU.

Expert Solution

Step 1

Introduction

The MINIX 3 operating system is a microkernel-based system that provides a reliable and secure environment for running user processes and managing system resources. One of the critical components of the operating system is its scheduler, which is responsible for allocating CPU time to various system processes and ensuring fair and efficient use of system resources. In this project, we propose a modification to the MINIX 3 scheduler to keep track of how much CPU time each user process has had recently and select the user process that has had the smallest share of the CPU when no task or server wants to run.
