It runs at a lower priority that the normal scheduler (this won't matter, unless you have a lot running in the normal scheduler), but uses slower pre-preemption ticks.

Web22 nov. 2013 · In linux system, scheduler consider processes and threads both as a task. It doesn't differentiate between process and thread while scheduling it. So, does this means that different cores executes different threads of different processes in parallel? When context-switch happens, does this happen only for one core or for all the cores of the cpu? WebThe Scheduler is responsible for two operations: continuously parsing DAG files and synchronizing with the DAG in the database continuously scheduling tasks for execution Those two tasks are executed in parallel by the scheduler and run independently of each other in different processes.
