- [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
- [19 Feb] On Thursday 22 February, Mike Papka will give a talk on ATM.

- CS 230 or CS 330.
- This course is a sequel to
Com Sci 230/330, covering
file systems, networking, and parallel systems. The course is
taught in response to popular demand from students who designed
the outline. The future existence and contents of the course
depend on future student interest.
