This PR adds two new search paths for the NVIDIA math libraries (cuSPARSE, cuBLAS, cuSOLVER). This fixes build issues on Polaris and Perlmutter.
* Add two new search paths for the NVIDIA math libs to configure
* Turn off CUDA math libs when CUDA is disabled
This PR fixes a few variable types inconsistencies arisen from the mixedint build. Additionally, it fixes the CUDA-11.1.1 build.
* Fix cuSPARSE version tag for using generic SpMM and new SpMV algorithms
* Bug fixes on hypre_ILU: S_row_starts computation and m -> big_m
* Bug fix: HYPRE_MPI_REAL -> HYPRE_MPI_COMPLEX
* Bug fix: HYPRE_Int -> HYPRE_BigInt
* Bug fix: HYPRE_MPI_INT -> HYPRE_MPI_BIG_INT

* added changes required for the new AMG benchmark, including a new routine that returns wall clock time and some new parameters which generate cumulative numbers of nonzeros for A, coarse grid and prolongation operators in AMG
Several bug fixes and small changes for the sycl build. Addition of full regression testing on florentia with consistent and correct results for struct and ij tests with sycl backend.
This PR modifies hypre_ParCSRMatrixGenerateFFFC to act as a wrapper between the host and device implementations. Consequently, hypre_ParCSRMatrixGenerateFFFCHost has been added.
This PR adds HIP support to MGR. Additionally:
* Add sanity checks at Setup and Solve functions
* Fix a bug in the computation of P_FF on MGR when using GPUs.
* Enable AMG level profiling with HIP
* Enable ROCTX regions in the IJ driver
* 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
