Computer Science 555 - Reading Report #4 -- Fall 2007

Due: Wednesday, November 14, 2007, 11:00 p.m.

• Compare and contrast the processor management approach of scheduler activations, Mach, Condor, and the Prospero Resource Manager. In answering this question discuss the knowledge available to different entities (kernel, process level schedule if applicable, programmer, user) and how this information is best used to optimize the allocation. Discuss also the kinds of environments within which each approach works best - especially with regard to management or ownership of resources (i.e. are resources all owned and managed by a single system, and are those interests aligned with the users interests).

GUIDELINE:

This is a lot to cover in so few words - so our advice is to write a first pass at your answer that is longer, and then edit out material that is redundant or not to the point. The use of tables can be very effective in conveying your ideas in a small area, but the tables must be integrated with your textual discussion, and not the only item in your submission.
