◆ IProbe()

template<int Tag>

static bool mfem::VarMessage< Tag >::IProbe	(	int &	rank,
		int &	size,
		MPI_Comm	comm
	)

inlinestatic

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.

Definition at line 479 of file communication.hpp.

◆ Isend()

template<int Tag>

void mfem::VarMessage< Tag >::Isend	(	int	rank,
		MPI_Comm	comm
	)

inline

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.

Definition at line 409 of file communication.hpp.

◆ IsendAll()

template<int Tag>

template<typename MapT >

static void mfem::VarMessage< Tag >::IsendAll	(	MapT &	rank_msg,

Definition at line 428 of file communication.hpp.

◆ Issend()

template<int Tag>

void mfem::VarMessage< Tag >::Issend	(	int	rank,
		MPI_Comm	comm
	)

inline

Non-blocking synchronous send to processor 'rank'. Returns immediately. Completion (MPI_Wait/Test) means that the message was received.

Definition at line 419 of file communication.hpp.

◆ Probe()

template<int Tag>

static void mfem::VarMessage< Tag >::Probe	(	int &	rank,

Definition at line 492 of file communication.hpp.

◆ RecvAll()

template<int Tag>

template<typename MapT >

static void mfem::VarMessage< Tag >::RecvAll	(	MapT &	rank_msg,
		MPI_Comm	comm

inlinestatic

Helper to receive all messages in a rank-to-message map container.

Definition at line 517 of file communication.hpp.

◆ RecvDrop()

template<int Tag>

void mfem::VarMessage< Tag >::RecvDrop	(	int	rank,
		int	size,
		MPI_Comm	comm
	)

inline

Like Recv(), but throw away the message.

Definition at line 507 of file communication.hpp.

◆ TestAllSent()

template<int Tag>

template<typename MapT >

static bool mfem::VarMessage< Tag >::TestAllSent ( MapT & rank_msg )

inlinestatic

Return true if all messages in the map container were sent, otherwise return false, without waiting.

Definition at line 450 of file communication.hpp.

◆ WaitAllSent()

template<int Tag>

template<typename MapT >

static void mfem::VarMessage< Tag >::WaitAllSent ( MapT & rank_msg )
