Are there nice mid-level pieces of documentation of the scheduler? If such documentation does not exist, is documentation on the scheduler independently of interest to people? As a related question, are there meaningful comparisons of different scheduler algorithms in different real world scenarios? The closest I've found is a paper of Abaffy-Kraj=C4=8Dovi=C4=8D, however I'm not equipped to understand whether their methodology is good or bad. *: The more research I've done the less clear it is that ULE is insufficient, so it's all sort of up in the air.
