Yohann Dudouit 05cf4c40b0 Add option to libCEED backend ':' is the option separator. 
- example: ./ex1 -pa -d ceed-cpu:/cpu/self/avx/blocked
  - bug: ./ex1 -pa -d ceed-cuda:/gpu/cuda/reg computes 'nan'
  - however, ./ex1 -pa -d ceed-cpu:/gpu/cuda/reg works
  - bug: ./ex1 -pa -d ceed-cpu:/gpu/cuda/ref crashes in libCEED
  - however, ./ex1 -pa -d ceed-cuda:/gpu/cuda/ref works...

Yohann Dudouit b69a90eb16 Initial commit for okina gpu libceed. 
Ceed and Cuda backend working together.

Use MFEM_SOURCE_DIR to find okl and cu files

Separate most of ceed integration in libceed.?pp

Veselin Dobrev 75065b0ea1 Addressing some feedback from the PR. 2019-05-24 10:25:34 -07:00
Veselin Dobrev b69fd1e038 Some tweaks and additions to the MemoryManager class. 
Modify the Device class to require the creation of an object in
order to use backends other then Backend::CPU. At destriction,
this object will call the Destroy() method of the MemoryManager to
deallocate any remaining registered device pointers.

In class Device, remove the method Disable() and make the method
Enable() private.

Use a global Array<double> as the buffer used by the cuda functions
for minimum and dot product.

Tzanio 3a860f124c Added a call to Device::Enable at the end of Device::Configure. 
Updated examples to use only Device::Configure (no more calls to Enable/Disable)
 2019-05-21 19:17:06 -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.
