template<class T >

void mfem::GroupCommunicator::Bcast	(	T *	data,
		int	layout
	)

Broadcast within each group where the master is the root. The data layout can be:

0 - data is an array on all ldofs 1 - data is an array on the shared ldofs as given by group_ldof

Definition at line 325 of file communication.cpp.

template<class T >

void mfem::GroupCommunicator::Bcast ( T * ldata )

inline

Broadcast within each group where the master is the root. This method is instantiated for int and double.

Definition at line 151 of file communication.hpp.

template<class T >

void mfem::GroupCommunicator::Bcast ( Array< T > & ldata )

inline

Definition at line 152 of file communication.hpp.

template<class T >

template void mfem::GroupCommunicator::BitOR< int > ( OpData< T > )

static

Reduce operation bitwise OR, instantiated for int only.

Definition at line 553 of file communication.cpp.

void mfem::GroupCommunicator::Create ( Array< int > & ldof_group )

Initialize the communicator from a local-dof to group map. Finalize is called internally.

Definition at line 273 of file communication.cpp.

void mfem::GroupCommunicator::Finalize ( )

Allocate internal buffers after the GroupLDofTable is defined.

Definition at line 299 of file communication.cpp.

GroupTopology& mfem::GroupCommunicator::GetGroupTopology ( )

inline

Get a reference to the group topology object.

Definition at line 139 of file communication.hpp.

Table& mfem::GroupCommunicator::GroupLDofTable ( )

inline

Fill-in the returned Table reference to initialize the communicator then call Finalize.

Definition at line 134 of file communication.hpp.

template<class T >

template void mfem::GroupCommunicator::Max< double > ( OpData< T > )

static

Reduce operation Max, instantiated for int and double.

Definition at line 535 of file communication.cpp.

template<class T >

template void mfem::GroupCommunicator::Min< double > ( OpData< T > )

static

Reduce operation Min, instantiated for int and double.

Definition at line 517 of file communication.cpp.

template<class T >

void mfem::GroupCommunicator::Reduce	(	T *	ldata,
		void(*)(OpData< T >)	Op
	)

Reduce within each group where the master is the root.

The reduce operation is given by the second argument (see below for list of the supported operations.) This method is instantiated for int and double.

Definition at line 419 of file communication.cpp.

template<class T >

void mfem::GroupCommunicator::Reduce	(	Array< T > &	ldata,
		void(*)(OpData< T >)	Op
	)

inline

Definition at line 170 of file communication.hpp.

template<class T >

template void mfem::GroupCommunicator::Sum< double > ( OpData< T > )

static

Reduce operation Sum, instantiated for int and double.

Definition at line 503 of file communication.cpp.
