A set of multigrid tutorials will be presented on Sunday, April 3rd. Attendance is open to all, and there is no charge or required registration. All the tutorials will be elementary in nature, and are designed to familiarize the audience with the basics of the topic.

A Multigrid Tutorial, Part I

8:30 am - 11:30 pm
Presented by Van Emden Henson

This presentation is an updated reincarnation of the tutorials Bill Briggs gave at Copper Mountain in 1987 and 1989. The 1987 tutorial led to the publication of the popular book, A Multigrid Tutorial (SIAM books), which has served as the introduction to multigrid for a good many workers in the field. Assuming no familiarity with multigrid, the tutorial introduces multigrid from first principles, examining basic iterative methods, coarse-grid correction, two-level approaches, and extending to multigrid methods.


A Multigrid Tutorial, Part II

1:30 pm - 4:00 pm
Presented by Van Emden Henson

In this section we will take up some "complications" that arise commonly in practice, and illustrate some of the techniques used to deal with them. These will be presented in simple, model-problem form.  Typical solution methods will be outlined.  Time constraints may prohibit coverage of all topics.



A Parallel Multigrid Tutorial

4:00 pm - 5:00 pm
Presented by Jim E. Jones

This presentation focuses on the issues involved in parallelizing a multigrid algorithm. Assuming no experience with parallel computing, but an understanding of the principles of multigrid, the tutorial introduces some of the standard and efficient techniques for developing a parallel multigrid solver. Contents *Algorithmic and implementation scalability *Parallelization of multigrid by domain partitioning *Performance models and metrics for parallel multgrid solvers


Morning and afternoon sessions will consist of individual talks of approximately 25 minutes each. Workshop and Circus sessions will be held in the evenings.


The program will include special time set aside for Workshops and Circuses. The Workshop Chair will encourage and support informal workshops on special topics of interest. The Circus Chair, for each of the planned circus sessions, will encourage participation and contributions and will organize, set the schedule, and oversee its progress.


We encourage special sessions on focus topics of interest. Anyone wishing to organizing such a session should contact
Van Henson. Anyone interested in contributing to a special session should contact the session chair.
