Load balancing plays a critical role in ensuring system stability and optimal performance, and as such, it has been a subject of extensive research across diverse computing domains, particularly in heterogeneous systems. Such systems integrate various computing devices with distinct architectures and computational power, each designed to execute a particular type of workload having diverse and immediate requirements. This research introduces a novel load balancing approach that utilizes machine learning to monitor the load distribution of heterogeneous systems in real-time. It estimates the load of the system's devices according to our proposed definition of the load. This definition provided us with an accurate measurement of the actual load, enabling our approach to detect imbalances and locate underloaded devices. Subsequently, our approach assigns applications to these underloaded devices to achieve load balance. We conducted a comparative analysis between our proposed approach and various established load balancing methods from diverse computing domains. This evaluation included three critical criteria: load balancing, workload execution time, and energy consumption. Additionally, we introduced a novel metric called "IMBALANCE" that quantifies the difference in load distribution among the system devices. We implemented each load balancing approach in a real-time heterogeneous system consisting of a master host and three worker servers each equipped with a Central Processing Unit and Graphical Processing Unit. To ensure a comprehensive validation of our approach, we conducted experiments in three distinct scenarios, involving different types of workloads having varying levels of computing intensity. The experimental results consistently demonstrate significant performance improvements of our approach across all scenarios. Our approach excels in minimizing system imbalance, which, in turn, enhances load balancing. This leads to reduced workload execution times and minimized device idle periods, ultimately improving energy efficiency. [ABSTRACT FROM AUTHOR] |
