Description: Global scheduling is a planning strategy in real-time operating systems characterized by considering all tasks in the system when making scheduling decisions. Unlike local approaches, where the scheduler focuses on a specific task or a limited set of tasks, global scheduling evaluates the entire system’s state, allowing for more efficient resource allocation and better management of execution time. This technique is particularly relevant in environments where multiple tasks must run simultaneously and where meeting deadlines is critical. Key features of global scheduling include the ability to adapt to changes in workload, optimization of CPU usage, and improved system predictability. Additionally, it allows for the implementation of complex algorithms that can prioritize tasks based on their urgency and timing requirements, resulting in more robust and reliable performance in critical applications. In summary, global scheduling is essential for ensuring that real-time systems can efficiently and effectively handle multiple tasks, ensuring that deadlines are met and available resources are optimized.
