Classes
class	mfem::Mpi
	A simple singleton class that calls MPI_Init() at construction and MPI_Finalize() at destruction. It also provides easy access to MPI_COMM_WORLD's rank and size. More...
class	mfem::MPI_Session
	A simple convenience class based on the Mpi singleton class above. Preserved for backward compatibility. New code should use Mpi::Init() and other Mpi methods instead. More...
class	mfem::GroupTopology
class	mfem::GroupCommunicator
	Communicator performing operations within groups defined by a GroupTopology with arbitrary-size data associated with each group. More...
struct	mfem::GroupCommunicator::OpData< T >
	Data structure on which we define reduce operations. The data is associated with (and the operation is performed on) one group at a time. More...
struct	mfem::VarMessage< Tag >
	Variable-length MPI message containing unspecific binary data. More...

Enumerations
