Earliest deadline first scheduling examples
WebMar 10, 2024 · Short description: Dynamic scheduling algorithm. 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 … WebJul 11, 2024 · We then focus on improving the optimality of real-time schedules. This is done by learning the principles behind dynamic scheduling methods.
