priority scheduling

priority scheduling

(operating system)
Processes scheduling in which the scheduler selects tasks to run based on their priority as opposed to, say, a simple round-robin.

Priorities may be static or dynamic. Static priorities are assigned at the time of creation, while dynamic priorities are based on the processes' behaviour while in the system. For example, the scheduler may favour I/O-intensive tasks so that expensive requests can be issued as early as possible.

A danger of priority scheduling is starvation, in which processes with lower priorities are not given the opportunity to run. In order to avoid starvation, in preemptive scheduling, the priority of a process is gradually reduced while it is running. Eventually, the priority of the running process will no longer be the highest, and the next process will start running. This method is called aging.

Most real-time scheduling using priority-based scheduling algorithm, this algorithm assigns a priority to the task, priority scheduling at each scheduling time with the highest priority task execution.
Understanding the application is no longer enough -- you now need to understand the context in which the app is used -- go to the user profile and understand the user and dynamically and automatically allow priority scheduling for the user.
