KAUST Research Conference on Divide, Conquer, and Combine Methods in Large-scale Simulation and Analytics, a.k.a. the 28th International Conference on Domain Decomposition Methods (DD28)

We are pleased to offer public access to the 11 plenary lectures of DD28 through the links below:

Martin Lanser: Robust nonlinear two-level domain decomposition methods

Simone Scacchi: Parallel solvers for virtual element nonlinear and saddle point problems

Miriam Schulte: How to (not) make multi-physics efficient, sustainable and fun

Hamdi Tchelepi: Scalable Numerical Simulation for Subsurface CO2 Sequestration the GEOS Framework

Gabriele Ciaramella: On space-time RAS methods for wave-type equations

Charbel Farhat: Think globally act locally: From domain decomposition to nonlinear projection-based model order reduction

Giancarlo Sangalli: Combining divide-and-conquer strategies in isogeometric solvers

Marco Discacciati: Overlapping domain decomposition methods for parametric elliptic problems via proper generalised decomposition

Heather Wilber: Superfast direct inversion methods for highly structured matrices

Jongho Park: Theory of subspace correction methods for convex optimization

Lulu Liu: Nonlinear preconditioning for implicit solution of discretized PDEs

A skeleton schedule of the conference is below:

Titles, abstracts, and biographies, wherever supplied by the presenter, can be found at the digital app "eventleaf guide" under the event "DD28".

Minisymposia on the following topics have been accepted (some occupy more than one block of four presentations):

  • Coarse Spaces and Transmission Conditions
  • Domain Decomposition and Machine Learning Algorithms
  • Domain Decomposition Methods for High Frequency Wave Propagation
  • HPC for Training Large Neural Network Models
  • Nonlinear Preconditioning Techniques and Applications
  • Novel Solution Techniques: Theory and Applications
  • Polygonal finite elements, Discontinuous Galerkin, and related methods
  • Schwarz Methods for Steady and Evolution Problems
  • Solvers for Innovative PDE Discretizations and Applications
  • Solvers for Large-Scale Parallel Computations
  • Time Parallel Time Integration
  • Transmission Conditions in DD and Optimal Control

A special feature of DD28 will be an Arabic-style majlis on "The Future of Domain Decomposition Methods."  Topics of discussion may include: problems in mixed dimensions (e.g., unions of domains consisting of segments modeled in 1D connecting subdomains modeled in 3D), multiphysics, nonlinear preconditioning, optimization applications, and neural network applications, and more.

For planning travel, the following should be of interest:

Sunday, 28 January is the arrival date.  There will be an opening reception Sunday evening.  There will also be an optional tutorial on domain decomposition methods and the PETSc software from 2 to 5pm on Sunday afternoon.  This optional pre-conference short course may be useful for first-time participants in the meeting.

The conference banquet, included in the registration fee, will be Tuesday evening, 30 January, on campus.

Thursday, 1 February is the departure day.  The conference program will end by noon and lunch is not included on Thursday.  It should be feasible for most participants to check out of their hotels Thursday morning and store their luggage either at their hotel or behind the operations desk in the conference venue.  The conference will arrange buses to the JED airport from the conference venue in response to sign-up demand.

Optional post-conference excursions may be planned to begin as early as 1:00pm on 1 February without missing any of the conference.  One such event is expected to be a walking tour of old Jeddah ("Al Balad") including open air and souk shopping opportunities and an open-air multi-course traditional Arabic dinner prior to late night flight departures.
