Public Member Functions

void AddElementRank (int elem, int rank)
 
- Public Member Functions inherited from mfem::ParNCMesh::ElementValueMessage< int, true, 157 >
int Size () const
 
void Reserve (int size)
 
void Add (int elem, int val)
 
void SetNCMesh (ParNCMesh *pncmesh_)
 Set pointer to ParNCMesh (needed to encode the message).
 
 ElementValueMessage ()
 
- Public Member Functions inherited from mfem::VarMessage< Tag >
void Isend (int rank, MPI_Comm comm)
 Non-blocking send to processor 'rank'. Returns immediately. Completion (as tested by MPI_Wait/Test) does not mean the message was received – it may be on its way or just buffered locally.
 
void Issend (int rank, MPI_Comm comm)
 Non-blocking synchronous send to processor 'rank'. Returns immediately. Completion (MPI_Wait/Test) means that the message was received.
 
void Recv (int rank, int size, MPI_Comm comm)
 Post-probe receive from processor 'rank' of message size 'size'.
 
void RecvDrop (int rank, int size, MPI_Comm comm)
 Like Recv(), but throw away the message.
 
 VarMessage ()
 
void Clear ()
 Clear the message and associated request.
 
virtual ~VarMessage ()
 
 VarMessage (const VarMessage &other)
 

Additional Inherited Members

- Static Public Member Functions inherited from mfem::VarMessage< Tag >
template<typename MapT >
static void IsendAll (MapT &rank_msg, MPI_Comm comm)
 Helper to send all messages in a rank-to-message map container.
 
template<typename MapT >
static void WaitAllSent (MapT &rank_msg)
 Helper to wait for all messages in a map container to be sent.
 
template<typename MapT >
static bool TestAllSent (MapT &rank_msg)
 Return true if all messages in the map container were sent, otherwise return false, without waiting.
 
static void Probe (int &rank, int &size, MPI_Comm comm)
 Blocking probe for incoming message of this type from any rank. Returns the rank and message size.
 
static bool IProbe (int &rank, int &size, MPI_Comm comm)
 Non-blocking probe for incoming message of this type from any rank. If there is an incoming message, returns true and sets 'rank' and 'size'. Otherwise returns false.
 
template<typename MapT >
static void RecvAll (MapT &rank_msg, MPI_Comm comm)
 Helper to receive all messages in a rank-to-message map container.

Detailed Description

Used by Rebalance() to send elements and their ranks. Note that RefTypes == true which means the refinement hierarchy will be recreated on the receiving side.
