EE5903 CA2: Simulation of FEST and EnSuRe, 2 fault-tolerant real-time scheduling algorithms that aim to improve energy savings in multicore systems.

Analysing Energy Consumption When Tolerating Faults in Two Real-Time Fault Tolerant Scheduling Algorithms on Heterogeneous Systems

FEST and EnSuRe are two fault tolerant scheduling algorithms for real-time heterogeneous multicore systems that has two types of processors: one or more low-power (LP) cores, and one high-performance (HP) core. They both use a backup overloading strategy with the goal of minimising the energy consumption of the system.

Requirements

Python 3.8

Setup

Clone this repository.

git clone https://github.com/djtfoo/FT-RT-Scheduling.git

The required Python libraries can be installed using pip via requirements.txt.

cd FT-RT-Scheduling
pip install -r ./requirements.txt

How to Run

Navigate to this directory. Then, launch Jupyter Notebook:

jupyter notebook

Open "FEST and EnSuRe Simulation.ipynb" and run the cells in order.
