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
