Detailed Description

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

Constructor & Destructor Documentation

MPIInputArchive()

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

inline

Construct an archive for receiving data via MPI.

Parameters

[in]	world	The world.
[in]	src	The source process.
[in]	tag	MPI communication tag.

Member Function Documentation

load()

template<class T >

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

inline

Deserialize 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 deserialized.

Parameters

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