In classes where you are responsible for presentting a paper, you present a summary of the paper to the class and then lead discussion of the paper, using reviews and questions provided by the rest of the class as needed. Hints for Computer System Design.

Applications that do not want this responsibility communicate with the exokernel through libOSes. Frans ; Engler, Dawson R.
