* The parameter of Vector::UseDevice(bool) no longer has a default value. All
the calls to UseDevice() in operator.cpp bilinearform_ext.cpp gridfunc.?pp and
linearform.?pp have been replaced with UseDevice(true).
* Added shortcuts for the device flags of the Memory objects inside the Vector
and Array classes:
bool Array::UseDevice()
bool Vector::UseDevice()
* The internal device flag in Memory::FlagMask is now called USE_DEVICE (it was
previously called EXEC_FLAG). The accessor function for this flag have been
renamed:
bool Memory::GetExecFlag() -> bool Memory::UseDevice()
void Memory::SetExecFlag(bool) -> void Memory::UseDevice(bool)
* Further renamed:
Memory::SyncWith -> Memory::Sync
Memory::SyncAliasToBase -> Memory::SyncAlias
Memory::SyncAliasToBase_ -> Memory::SyncAlias_
* Replaced FIXME with TODO in general/mem_manager.cpp
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.
This matches the names of the functions in mm:: and also more closely
matches their use in the rest of mfem.
Also removed the template parameter for mm::free since it is not needed.
It is possible in the future to add equivalents of new and delete to the
mm class (with different names since those are keywords) in case it is
desirable to call the constructor and destructor.
In class ParMesh:
* Introduced internal struct's Vert3 and Vert4 holding 3 and 4
integers, respectively.
* Replaced 'shared_faces' with two separate arrays 'shared_trias'
and 'shared_quads' with types Array<Vert3> and Array<Vert4>,
respectively.
* Removed the arrays 'stria_lface', 'squad_lface', 'stria_sface',
'squad_sface', and 'sface_stype'.
* Restore the array 'sface_lface' used previously. Shared face
indices are shred triangle / quad indices offset by 0 / "number
of shared triangles", respectively.
* Made the two RefineGroups methods protected.
* Added two new protected methods: UniformRefineGroups2D and
UniformRefineGroups3D. These two methods simplify the
implementations of almost all uniform-refinement methods in
the class.
* Fixed a bug in ReorderTetMesh that was causing ex8p to fail with
fichera-mixed.mesh.
* Updated the implementations of all ParMesh methods as necessary
due to the above changes.
In class Triangle, add a static method MarkEdge that works on a
given array of 3 indices.
In class Array, add a method CopyTo - implemented using std::copy.
