Trilinos Release 16.0 Release Notes July, 2024

A large number of packages have been marked as deprecated in this release.
We are planning to remove them in the fall of 2025. The list of packages is

  • Amesos
  • AztecOO
  • Epetra
  • EpetraExt
  • Ifpack
  • Intrepid
  • Isorropia
  • ML
  • NewPackage
  • Pliris
  • PyTrilinos
  • ShyLU_DDCore
  • ThyraEpetraAdapters
  • ThyraEpetraExtAdapters
  • Triutils

If you are a user of one of these packages, please transition to the newer
software stack. If you need guidance with finding an adequate replacement
or are missing a particular feature, please open an issue or a discussion
on Github.

Amesos2

  • Add interface to MKL cluster sparse solver.
    #13073

Framework

  • Marked all deprecated packages as 'Secondary Tested'.
  • Reset default for Trilinos_ENABLE_SECONDARY_TESTED_CODE to OFF.
    This will cause the previously-mentioned deprecated packages to NOT be
    automatically enabled to help guide users away from them. The old
    behavior can be restored by setting the variable back to ON, but note
    that the recommended best practice is to explicitly enable packages that
    the user is depending on (e.g. if you depend on ThyraEpetraAdapters, enable
    that explicitly instead of Thyra and Epetra and allowing TriBITS to enable
    the adapters).
  • Added deprecation warnings to all deprecated packages. The warnings are able
    to be disabled via the Trilinos_SHOW_DEPRECATED_WARNINGS option (this is
    also available as a per-package option). These warnings are intended to
    notify users that package capability they are using will be removed in upcoming
    releases.
    #12828

Ifpack2

  • RBILUK now supports Kokkos Kernels as a backend
    #12911

Kokkos, Kokkos Kernels

  • Inclusion of version 4.3.1 of Kokkos and Kokkos Kernels
    #12995

NOX

  • Added preconditioner reuse across multiple nonlinear solves.
    #12986

Teko

  • Add Hierarchical Block Gauss-Seidel Capability
    #13040

Tpetra

  • Some Tpetra features can be toggled via environment variables.
    When an unrecognized variable is found, Tpetra now throws to alert
    to potentially misspelled variables.
    #12944

  • Add a test that checks that vendor TPLs for sparse matrix-vector product
    are called.
    #13018

  • Add team parallelism to kernels associated with matrix equilibration.
    #13017

Amesos2

  • The interface to SuperLU_DIST now also works for the CUDA-enabled
    variant of the library.
    #12524

Framework

  • Began using semantic versioning for Trilinos with 15.1.0 release.

Ifpack2

  • BlockRelaxation can now generate blocks using a Zoltan2.
    #12728

Kokkos & Kokkos Kernels

  • Inclusion of version 4.2.1 of Kokkos and Kokkos Kernels
    #12707

MueLu

  • The reformulated Maxwell solver (RefMaxwell) was generalized to
    also work for grad-div / Darcy flow problems.
    #12142

  • In an effort to consolidate the old non-Kokkos code path with the
    newer Kokkos code path, the following factories were deprecated
    and should be removed from input decks: NullspaceFactory_kokkos,
    SaPFactory_kokkos, UncoupledAggregationFactory_kokkos.
    #12720
    #12740

Panzer

  • MiniEM can now also assemble and solve Darcy problems using first
    or higher order mixed finite elements.
    #12142

PyTrilinos2

  • New package that auto-generates Python interfaces for Trilinos
    packages. Currently, most of Tpetra is exposed. We are planning on
    adding other packages.
    #12332

ROL

  • An auto-generated Python interface was added. A standalone Python
    package can be downloaded from rol.sandia.gov
    #12770

Teko

  • Block Jacobi and Gauss-Seidel methods allow now to specify
    preconditioners for the iterative solves of the diagonal blocks.
    #12675

Tpetra

  • Tpetra will now assume by default that the MPI library is GPU
    aware, unless automatic detection or the user indicates otherwise.
    #12517

  • Reject unrecognized TPETRA_* environment variable. Misspelled or
    removed environment variables are no longer silently ignored.
    #12722

  • In order to allocate in shared host/device space (i.e.
    CudaUVMSpace, HIPManagedSpace or SYCLSharedUSMSpace) by default,
    please use the CMake options
    KokkosKernels_INST_MEMSPACE_CUDAUVMSPACE=ON
    Tpetra_ALLOCATE_IN_SHARED_SPACE=ON
    #12622

Trilinos 15.0.0

CMake

  • Change the default for Trilinos_MUST_FIND_ALL_TPL_LIBS from OFF to
    ON. It was turned off by default because it breaks backward
    compatibility but it also causes problems for new users and new
    configurations.

    Users that do not want this new behavior can set
    -D Trilinos_MUST_FIND_ALL_TPL_LIBS=OFF, which is backward compatible.

  • Change the default for Trilinos_USE_GNUINSTALLDIRS from OFF to ON,
    in the goal to move Trilinos and TriBITS to modern CMake.

    TriBITS has had the ability to use that paths selected by the standard
    CMake module GNUInstallDirs.cmake for a long time. But it is turned off
    in TriBITS by default and was never turned on in Trilinos, both for the
    sake of backward compatibility.

    This may break people's existing configurations because it will install
    libs in <prefix>/libs64/ instead of in <prefix>/libs/ on many systems
    (e.g. Linux systems). For example, this will break downstream CMake
    projects that call find_package(Trilinos ...) before defining the
    compilers (e.g. so they can get the compilers from Trilinos). If the
    compilers are not defined, find_package() will not search
    <prefix>/lib64. To revert back to using <prefix>/lib but still use
    GNUInstallDirs.cmake for Trilinos, set -D CMAKE_INSTALL_LIBDIR:STRING=lib when configuring Trilinos. To avoid the
    find_package(Trilinos ...) problem not searching <prefix>/lib64,
    consider explicitly specifying the compiler to and having the downstream
    CMake project define the compilers first with project(<ProjectName> COMPILERS C CXX ...) before calling find_package(Trilinos ...). (That
    is, don't try to get the compilers from the installed Trilinos, see
    #12306.)

    NOTE: The setting -D Trilinos_USE_GNUINSTALLDIRS=OFF is deprecated and
    may be removed in the future. (I.e. the usage of GNUInstallDirs.cmake
    may be hard-coded in the future so please try adjusting to the usage of
    GNUInstallDirs.cmake by Trilinos.) See
    #12104 (comment)
    for additional details and instructions.
