Unified the implementation of AssembleDiagonal in one place
in BilinearForm which also works in parallel (using the virtual
call GetProlongationMatrix).
and transfers.
The Memory class is now used by some MFEM classes (like Array and
Vector) which can be used on the Device. Such classes now provide
methods to access the underlying Memory object, e.g. GetMemory.
Updated ex1/ex1p and ex6/ex6p to not need to enable/disable the
Device at specific points -- the Device is now enabled just at the
start. Also, the same examples can now run on Device (e.g. -d cuda)
without the partial assembly option (-pa) -- full assembly will
be still done on CPU but the sparse matrix action and vector
operations will be done using the Device.
Reverted changes in class DenseMatrix related to using the Device.
At this point, DenseMatrix operations are only used for small matrices
and using the Device in this case is not a good option.
- added an abstract class OptimizationSolver (inheriting from IterativeSolver) common to all optimizers
- Hiop optimizers returns the solution
- spec class for Hiop updated
- to work with local vectors
- to correctly copy from input mfem vectors
- compute vector distribution without relying on dynamic casts to hypre vectors
- plus other smallish changes
* Print the relative error, ||r||/||r_0||, in addition to the
absolute error, ||r||.
* In the method ComputeScalingFactor, pass the optional rhs, b,
instead of the correction vector, c, which can be accessed by
derived classes as a data member of the class. Same holds true
for the residual vector, r.
general/globals.[ch].
Renamed class WrappedOStream to OutStream and use a different
implementation in order to support the case when the OutStream is passed
as a parameter of type std::ostream.
In class MPI_Session, added an MPI_Comm parameter to both constructors,
with a default value of MPI_COMM_WORLD.
Hide the global variable MFEM_COMM_WORLD and allow access (read and
write) with global functions: GetGlobalMPI_Comm() and
SetGlobalMPI_Comm() - in the future, we may want to perform some tasks
when changing the "global" MPI communicator.
In mfem_error(), use GetGlobalMPI_Comm() instead of MPI_COMM_WORLD.
Minor formatting changes and #include reordering.
