Preconditioning 2022
International Conference on Preconditioning Techniques for Scientific and Industrial Applications

The goal of this series of conferences is to address the complex issues related to the solution of general sparse matrix problems in large-scale applications and in industrial settings.

Date June 08 - 10, 2022
Time schedule The program is available here.
Scientific topics

The topics to be covered at the conference include, but are not limited to, the following:

  • incomplete factorization preconditioners
  • domain decomposition preconditioners
  • approximate inverse preconditioners
  • block preconditioning
  • multi-level preconditoners
  • graph and mesh partitioners
  • preconditioners based on randomization
  • preconditioning techniques for finite element discretizations
  • preconditioning multiphysics problems
  • preconditioning in data science and machine learning
  • preconditioning techniques in eigenvalue computation, optimization problems
  • applications including but not limited to: computational fluid dynamics, materials science and nanosciences, image processing, petroleum industry, semiconductor device simulations, computational finance, and data science


We currently have the following minisymposia:

  • Structured Linear Systems Resulting from Problems Involving PDEs (Santolo Leveque and John Pearson, University of Edinburgh)
  • Preconditioning Techniques for Application Problems in Computational Science and Engineering (Fabian Castelli, KIT)
  • High Performance Preconditioning on GPUs (Hartwig Anzt, Karlsruhe Institute of Technology Yvan Notay, UniversitĀ“e Libre de Bruxelles) (open for possible further contributions)
  • Preconditioning for data assimilation and least squares problems (Melina Freitag, University of Potsdam)
feel free to add to that list.

Accomodation With the keyword "Preconditioning" you may book discounted rooms in the following hotels:
Travel Chemnitz is best reached via plane to Leipzig (LEJ) or Dresden (DRS) both of which are well connected to Frankfurt and Munich. From both airports we will arrange collective pickups using the university shuttle service. If you want to reach Chemnitz via train there are connections via Chemnitz and Leipzig and a new connection to Berlin has just been announced, which might make flying to Berlin also more convenient.

If you plan to arrive a bit earlier or leave later than Prague is relatively close (90 minute drive) and might also make a viable destination for departure or arrival.

For those of you traveling to the Householder meeting in Bari, there seems to be a one-stop flight leaving from Leipzig around lunch time on Friday and Saturday. Please do not hesitate to contact us about further details.

Shuttle service:
We have some spots available in the university shuttle to and from the local airport, which are
