This commit introduces three new variables to the 'HYPRE_config' file through both the autoconf and CMake builds. They are defined only when there is a '.git' directory present, and are otherwise left undefined. These new variables may help users who work directly with the development branch of hypre to keep their code current and backward compatible with previous releases and also individual commits between those releases. The new variables are:
HYPRE_DEVELOP_STRING - a string created from the 'git describe' command that indicates the last release tag, the number of commits beyond that last release, and the corresponding commit hash.
HYPRE_DEVELOP_NUMBER - the number of commits since the last release.
HYPRE_DEVELOP_BRANCH - defined only if the main development branch is being used, and is set to the name of that branch (currently master).
The commit also adds runtime regression tests for the variables in the 'src/test' directory.
This PR adds the hypre_IntArray data structure, which wraps HYPRE_Int* and includes
memory location and size information. The CFMarker and DofFunc arrays in BoomerAMG
are wrapped with hypre_IntArray, and their default location is moved to the device when
using GPU acceleration, avoiding some copies between host and device.
This PR improves the performance of hypre's sparse matrix-matrix on NVIDIA GPUs, and fixes it on AMD GPUs with hip.

MSVC does not support the max operation in OpenMP reduction clauses. This adds a code branch for doing reduction with OpenMP by using a critical region instead when MSVC is used. Fixes issue #460
The timers in hypre date back a really long time and did not originally use MPI_Wtime(). This (finally) changes the default to be MPI_Wtime() whenever MPI is also being used.
This PR ports the Neumann version of AIR to the GPU. New features include:
1. Construction of Neumann AIR restriction operator R on the GPU
2. Construction of one-point interpolation on the GPU
3. Construction of an absolute value version of the strength of connection matrix on the GPU
4. CF relaxation for Jacobi (relax7) and L1 Jacobi (relax18) on the GPU - note that this does redundant computation since a full matvec is called when only relaxing either C- or F-points
5. Regression tests for AIR
6. Filtering for ParCSR matrices based on tol*row_norm for 1-, 2-, and infinity-norm on the GPU
This PR addresses #404. Includes the typo fixes, and changes to .saved due to inclusion of -ns 2. Also, fixed the memory issues after fixing the .jobs

This PR reimplements hypre_ParCSRMaxEigEstimate using Gershgorin discs, which ensures that max_eig and min_eig are both allreduced across all ranks so that the return value of the function is the same for all ranks.

This PR improves the IJ interface with new functions, performs code reorganization, and simplifies coding by removing ownership info related to the partitioning data members from ParCSRMatrix and ParVector objects. A more comprehensive list of changes is given below:
* Add HYPRE_IJMatrixAdd, HYPRE_IJMatrixNorm and HYPRE_IJMatrixTranspose functions
* Add ParCSRMatrixInfNorm and ParCSRMatrixReorder functions
* Add transpose, add and norm functions to IJMatrix
* Add more caliper annotation to BoomerAMG and ParCSR functions
* Fix typo in assumed partition function and add caliper annotation
* The output matrix from ParTMatmul owns row/col starts.
* Build communication package for A at ParTMatmul if it does not exist.
* Move hypre_Log2 to utilities
* Add HYPRE_ANNOTATE_REGION_[BEGIN,END] to caliper annotation
* Phase out [row,col]_starts ownership info in ParCSR matrices
* Remove partitioning ownership info from vector
* Move partitioning variables to stack memory
This was originally started as an effort to
fix the Windows+CUDA build, in which case
these special flags need to be added differently
when CUDA is used.
However, they were there to workaround issues in
earlier MSVC versions that today's version doesn't
have, so the changes here actually just check
whether the MSVC being used is old enough to need
these workarounds.
Since using CUDA and MSVC through CMake is relatively
new, there shouldn't be a need to support these
workarounds with CUDA
This PR adds GPU support for ams, ame and ads, and the following parcsr operations on GPUs, ParCSRAdd, ParCSRTranspose, l1 hybrid G-S/SSOR.
