Veselin Dobrev 7a869c30c6 In class TimeDependentOperator, add a new property: evaluation 
mode, see TimeDependentOperator::SetEvalMode() for description.
This new property is now used to support IMEX time integration
in class ARKStepSolver. With this addition the method
TimeDependentOperator::SUNImplicitMult() is no longer needed
and was removed.

Tzanio e36d1ea8fd Several change to (hopefully) simplify the interface: 
* 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

Tzanio c3999ba78b A few shortcuts for Vector + Memory 2019-05-22 08:16:12 -07:00
Veselin Dobrev 40378a046b Introduce a new Memory class for handling host + device allocations 
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.
