Dynamic Load Balancing

Definition

Dynamic load balancing is a method used in high-performance computing to efficiently distribute workloads across multiple resources, such as processors or servers, in real-time. This technique helps to optimize resource utilization, minimize processing time, and reduce bottlenecks by continuously monitoring and redistributing tasks based on current system loads and performance metrics. By dynamically adjusting the workload distribution, this approach enhances overall system performance, particularly in complex bioinformatics applications that require significant computational power.
