Earliest deadline first scheduling
WebFeb 13, 2024 · The Earliest Deadline First (EDF) scheduling algorithm is a dynamic priority scheduling algorithm that is commonly used in real-time systems. In this algorithm, tasks are assigned deadlines, and the task with the earliest deadline is given the highest priority. This algorithm ensures that the most critical task is executed first and prevents ...

Earliest deadline first scheduling
Did you know?
Earliest deadline first (EDF) or least time to go is a dynamic priority scheduling algorithm used in real-time operating systems to place processes in a priority queue. Whenever a scheduling event occurs (task finishes, new task released, etc.) the queue will be searched for the process closest to its deadline. This process is the next to be scheduled for execution.
