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.
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.
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.
Workshops and Circus Sessions
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
