Detailed Description

Archive allowing buffering, serialization of data, and point-to-point communication between processes with MPI.

Constructor & Destructor Documentation

MPIOutputArchive()

madness::archive::MPIOutputArchive::MPIOutputArchive ( World &  world, const ProcessID &  dest, int  tag = SafeMPI::MPIAR_TAG  )

inline

Construct an archive for sending data via MPI.

Parameters

[in]	world	The world.
[in]	dest	The destination process.
[in]	tag	MPI communication tag.

References bufsize, and v.

~MPIOutputArchive()

madness::archive::MPIOutputArchive::~MPIOutputArchive ( )

inline

Destructor. Close the archive first, which may entail sending data.

References close().

Member Function Documentation

close()

void madness::archive::MPIOutputArchive::close ( )

inline

Close the archive (i.e., send any data in the buffer).

References flush().

Referenced by ~MPIOutputArchive().

flush()

void madness::archive::MPIOutputArchive::flush ( ) const

inline

Send all data in the buffer to the destination process.

Todo:

Check out the "?? why ??" comment.

References bufsize, dest, madness::World::mpi, madness::WorldMpiInterface::Send(), tag, v, and world.

Referenced by close(), madness::archive::ArchiveStoreImpl< ParallelOutputArchive< localarchiveT >, WorldContainer< keyT, valueT > >::store(), and store().

store()

template<class T >

std::enable_if< is_trivially_serializable< T >::value, void >::type madness::archive::MPIOutputArchive::store ( const T *  t, long  n  ) const

inline

Serialize data and store it in the buffer.

The function only appears (due to enable_if) if T is fundamental.

Template Parameters

T	The data type to be serialized.

Parameters

[in]	t	Pointer to the data.
[in]	n	Number of data items to serialize.
