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:

  • Inclusion of version 5.1.1 of Kokkos and Kokkos Kernels
    #15035
    #15198

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
