[PDF][PDF] A unified framework for adaptive BDDC

C Pechstein, CR Dohrmann - Electron. Trans. Numer. Anal, 2017 - etna.math.kent.edu
In this theoretical study, we explore how to automate the selection of weights and primal
constraints in BDDC methods for general SPD problems. In particular, we address the three …

Multilevel balancing domain decomposition at extreme scales

S Badia, AF Martín, J Principe - SIAM Journal on Scientific Computing, 2016 - SIAM
In this paper we present a fully distributed, communicator-aware, recursive, and interlevel-
overlapped message-passing implementation of the multilevel balancing domain …

Adaptive BDDC in three dimensions

J Mandel, B Sousedík, J Šístek - Mathematics and Computers in Simulation, 2012 - Elsevier
The adaptive BDDC method is extended to the selection of face constraints in three
dimensions. A new implementation of the BDDC method is presented based on a global …

Multilevel balancing domain decomposition by constraints deluxe algorithms with adaptive coarse spaces for flow in porous media

Adaptive-multilevel BDDC and its parallel implementation

B Sousedík, J Šístek, J Mandel - Computing, 2013 - Springer
We combine the adaptive and multilevel approaches to the BDDC and formulate a method
which allows an adaptive selection of constraints on each decomposition level. We also …

A highly scalable parallel implementation of balancing domain decomposition by constraints

S Badia, AF Martín, J Principe - SIAM Journal on Scientific Computing, 2014 - SIAM
In this work we propose a novel parallelization approach of two-level balancing domain
decomposition by constraints preconditioning based on overlapping of fine-grid and coarse …
