Release Notes by Package
Compadre:
- Inclusion of version 1.7.0
#15023
Ifpack2:
-
Added runtime debug control via the IFPACK2_DEBUG environment variable.
#15166 -
Fixed missing parILUT max-iteration setup.
#15094 -
Add optional row/column 1-norm equilibration of the inner subdomain matrix
in additive Schwarz
#15241
Kokkos, KokkosKernels:
MueLu:
-
Energy minimization multigrid has been completely refactored. The algorithm
now runs on device and uses Belos to solve the optimization problem.
#14989 -
An energy minimization preconditioner for Maxwell problems has been added.
#15215
#15216
#15218 -
Fixed several correctness issues in MultiPhys, Hierarchy setup, and TekoSmoother application.
#15028
#15082
#15173
#15178
Rapid Optimization Library (ROL):
-
Multi-objective optimization methods, including the sampling of
the Pareto frontier using convex combinations of objective
functions as well as the normal boundary intersection method. -
Interface for robust optimal experimental design (OED) which can
account for uncertainty in parameter estimates as well as randomly
failing experiments. -
Improved OED interface that enables OED for vector valued
estimation problems. -
Implementation of greedy OED that leverages fast numerical linear
algebra and that can be used for solution verification and
producing initial guesses for optimization. -
New methods for nonsmooth optimization represented as Type-P
"proximable" problems, where the objective function is a sum of a
smooth nonlinear nonconvex function and a nonsmooth convex
function.
ShyLU:
- Performance improvements in Tacho
#15120
Tpetra:
-
The computation of global constants in Map construction is now optional.
This allows skipping global reductions.
#15093 -
Ongoing effort to move more map and import/export computations to device.
#14902
#14908 -
Added matrix-matrix product support for preserving explicit zeros in the
sparsity pattern when requested.
#15019
