Key Features

Dynamic Priorities

Automatically adjusts task priorities based on current system workloads.

Real-Time Scheduling

Ensures tasks are scheduled based on strict deadlines and real-time requirements.

Workload Adaptation

Adjusts to changing system workload dynamically, enhancing efficiency.

Algorithm Overview

Our adaptive scheduling algorithm adjusts priorities in real-time based on workload changes and deadlines. Below are the two key algorithms implemented:

Rate-Monotonic Scheduling (RMS)

Rate-Monotonic Scheduling (RMS) is a fixed-priority algorithm where tasks with shorter periods (i.e., tasks that need to execute more frequently) are assigned higher priorities. It is optimal for static task sets in real-time systems.

  • Priority is assigned based on task period: the shorter the period, the higher the priority.
  • Best suited for periodic tasks with fixed deadlines.
  • Optimal for systems where tasks do not change dynamically.
  • Used in systems where predictability and deadlines are key.

Earliest Deadline First (EDF)

Earliest Deadline First (EDF) is a dynamic priority algorithm where tasks with the earliest deadlines are given the highest priority. It is optimal for systems where tasks may vary and deadlines can be flexible.

  • Priority is based on the task's deadline: the earlier the deadline, the higher the priority.
  • Best suited for systems where tasks have varying deadlines.
  • Can adapt dynamically to workload changes.
  • Optimal for systems where deadlines are more critical than periodicity.
