Thir PR adds a factorized sparse approximate inverse (FSAI) implementation on hypre, which can be used as a standalone solver, preconditioner to Krylov methods, or complex smoother to BoomerAMG. Particularly, we consider the adaptive algorithm version, where the sparsity pattern of the lower triangular factor G is built dynamically, i.e., during an iterative procedure that tries to find the best nonzero positions for a given row of G. This implementation was performed on top of the IJ interface. It uses the diagonal portion of A for constructing G, i.e., it's a block-Jacobi method in the MPI sense. List of additional changes:
* Add caliper instrumentation to FSAI.
* Add ZeroGuess option to FSAI.
* Performance optimizations.
* Add OpenMP support to FSAI.
* Make internal BLAS/LAPACK functions thread-safe.
* Update CMake build.
* Add new test cases: beam_tet_dof459_np1, beam_hex_dof459_np2, and beam_tet_dof2475_np4.
* Add documentation for FSAI.

* fixed MM-multipass interpolation for case of no C-points
* fixed the issue of isolated groups of fine points and added a regression test.
* corresponding changes to the device code

This PR extends the (semi)-struct matrix/vector IO functions added on #583 with GPU support. Additionally:
* Fix regression tests on Lassen.
* Read data values into host memory
* Update Umatrix read algorithm when the ParCSRMatrix is expected to live on the device
* Reset deallocated pointers at hypre_IJMatrixDestroyParCSR to NULL
* Clone rownnz info if present on a CSRMatrix
* Reduce memory transfer and remove unused variables
* Fix bug with -print option
* Build rownnz info also when the ParCSRMatrix is in assembled state
* Remove a few instances of "return ierr"
* Refactor (s)struct IO - code works with cuda and without UM
* Add executables to gitignore
This PR adds support for native print/read functions of SStructMatrix and SStructVector. Other important changes are:
* Add public functions for reading StructMatrix and StructVector.
* Add a new set of regression tests called "io" to the TEST_sstruct folder.
This PR fixes issue #556.
AC_CHECK_FILE was being used to test the existence of the .git folder. However, according to Autoconf manual, it does not work when cross-compiling. This PR implements another strategy for looking for the .git folder which works also when doing cross-compilation.
Enable GPU setup for MGR solver.
* Added device specific functionality for interpolation
* Made device and host calls to interpolation consistent
* Edited IJ driver to use GPU capable options for MGR
* Updated saved files for new GPU options
* Updated CMakeLists to support new MGR capabilities

This adds matvec, matrix transpose, and vector operations (axpy, inner product, etc.)
with sycl backend (via oneMKL and oneDPL) for running on Intel GPUs. Thus, the AMG
solve phase can now execute entirely on Intel GPUs.
This PR adds Fortran interfaces for hypre_MGR and hypre_ILU. Additionally:
* Add ArrayArray types in `fortran.h`
* Add MGR and ILU options to the fortran interfaces for Krylov solvers
Usually consumers of HYPRE call find_package(HYPRE) and depend on
HYPRE::HYPRE target. But they could also want to use HYPRE via
add_directory (for instance via a git submodule)) or FetchContent,
in which case they have to depend on HYPRE target.
This alias makes this usage more consistent, all users could then
depend on HYPRE::HYPRE. See for instance
https://cmake.org/pipermail/cmake/2018-November/068629.html
if HYPRE_WITH_CALIPER is enabled,
then actually find the CMake package
for caliper and link to it.
Without this, include files are not
found and the caliper library is not
properly linked.
This PR adds automatic indentation using Artistic Style (astyle). The script config/astyle-apply.sh runs the indentation using the configuration file config/astylerc. The script also runs headers in all of the directories that automatically generate internal _hypre_*.h header files. Much of this was borrowed from the MFEM project. A pre-commit git hook was also added.
The 'test/Makefile' had the '..' directory in the include path, which caused the 'HYPRE_config.h' file to be included from two different places (in '..' and in 'install'). In the spack autotest, this caused a conflict.
* Check that 'git describe' works in autoconf build
* Updated versioncheck tests to work when 'git describe' fails
* Updated CMake build to work when 'git describe' fails
* Update autotest filters to ignore error messages from 'git describe'
