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

Trilinos 15.1.0

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

trilinos-release-15-0-0

3703c19

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.
