* Fixing the FEI interface to SuperLU_Dist. This uses the same structs
as src/parcsr_ls/dsuperlu.c.
* Updates to the CMake build system and other spots to support SuperLU_Dist, SuperLU, and the FEI.
Some Windows build bits.
* Reverting this change, it's just in the comments.
* Changes from Tim Dunn's FEI branch (feature/dunn13/tad220914-fei).
This prevents the solver from exiting out with a failure even though
the initial guess is the solution. There is also a fix to prevent a
floating point exception.
* Removing this #ifndef, as it is no longer necessary for our Windows build.
* Only enable CXX if building the FEI.
This PR updates hypre_device_allocator to use hypre's abstract memory model. This means that:
hypre configured with unified memory support: those allocations will be on managed memory.
hypre configured without unified memory support: those allocations will be on device memory.
This PR enables 2-stage GS relaxation to work properly with multi-component vectors.
* some optimizations to get 2-stage GS working faster
* Update loop unrolling at DiagScaleVector2
* computeY is a template argument now

This PR adds a new variable in `HYPRE_config.h` for naming the hypre's branch currently in use. Internal drivers have been updated to use this variable
* Add HYPRE_BRANCH_NAME to Makefile and cmake builds
* Run config/update.sh
* Ignore files generated by cmake in the cmbuild folder
* Update drivers
* Update regression tests
This PR enables the use of Krylov methods for solving linear systems with multi-component vectors. Regression tests have been added on src/test/TEST_ij/vector.sh. Additionally, hypre_ParCSRDiagScaleVector and hypreDevice_DiagScaleVector have been extended to work with multi-component vectors.
* Small changes to support multi-component Krylov algorithms. This seems to work with GMRES.
* Extend hypre_ParCSRDiagScaleVector to multicomponent vectors
* Extend hypreDevice_DiagScaleVector to multicomponent vectors
* Test Krylov solvers support for multi-component vectors
* Update result for the final residual norm (Tux)
* Add hypreGPUKernel_CSRMatvecShuffleGT8 and update hypreDevice_CSRMatrixMatvec with new kernel dispatching strategy
* Add number of matvecs as a command line option for the IJ driver
* Add vector.saved.lassen and vector.saved.arcticus files
* Run astyle

* Add device functions to perform strided copy
* Extend BoomerAMG with L1-Jac to vectors with multiple components
* Add ParVectorSetLocalSize calls to MGR
* Extend hypre_ParCSRCommPkg with a new member (num_components) that allows communicating several vector components at once.
* Add hypre_ParCSRCommPkgCreateAndFill for allocating and filling a communication package with its data.
* Improve parallel SpMV performance for vectors with multiple components

This is part of a series of PRs for enabling BoomerAMG to be applied to vectors with multiple components.
* Extend hypre's SpMV on CUDA to multivectors and add calls to cusparse's SpMM.
* Add loop unrolling to hypre's SpMV on CPUs when using multivectors with less than 5 components.
* Add HYPRE_SPMV_FILL variables to hypre's SpMV on GPUs
* Add SYCL changes to SpMV

* This commit adds the public and internal APIs for doing jacobi approximation to iterative triangular solve. At the moment, this code simply sets parameters for the ILU classes.
* Fixing defaults, docs, and comments.

* Add new device functions needed by multivectors (`hypreDevice_IntStridedCopy` and `hypreDevice_IVAMXPMY`)
* Extend `hypre_SeqVectorElmdivpy` to work with multivectors.
Ports some missing routines to allow the IJ driver to run without unified memory with the sycl backend:
IJ vector set/add values and assembly
Routines in par_coarse_parms_device.c
hypre_ParCSRComputeL1Norms()
This PR enables Set/AddTo/GetValues for multivectors through the IJ interface. It also adds regression tests for the new functionalities (TEST_ij/vector) and the HYPRE_IJVectorInnerProd function
This adds sycl support for interpolation optionsExtInterp, ExtPIInterp,
and ExtPEInterp (which correspond to InterpType 6, 14, 16, 17, 18).
Generation of the strength matrix is also ported to sycl.
Further unification of cuda/hip/sycl kernel functions.
Adds regression tests for the sycl backend on arcticus including both ij and struct tests.
