• [22 Feb] Assignment for Tuesday, 27 February. Read the paper, "Scheduler Activations: Effective Kernel Support for the User-Level Management of Parallelism," by Anderson, Bershad, Lazowska, Levy. Be prepared for a thorough discussion of the paper. I think that "scheduler activations" constitute the first significant structural idea that we have encountered in our study of distributed systems. The paper is not hard to read. There is a good discussion of the weakness of kernel threads, which stands by itself. The main problem is that the definition of "scheduler activations" is tangled up with the explanation of their use in supporting user threads. Please concentrate particularly on extracting a precise definition of the proposed kernel interface, and consider possible variations on it.
