Description

The packed_iarchive class is an Archiver (as in the Boost.Serialization library) that packs binary data into a buffer for transmission via MPI. It can operate on any Serializable data type and will use the MPI_Pack function of the underlying MPI implementation to perform serialization.

`packed_iarchive` public construct/copy/destruct

packed_iarchive(MPI_Comm const & comm, buffer_type & b, 
                unsigned int flags = boost::archive::no_header, 
                int position = 0);

Construct a packed_iarchive for transmission over the given MPI communicator and with an initial buffer.

Parameters:

`b`	A user-defined buffer that will be filled with the binary representation of serialized objects.
`comm`	The communicator over which this archive will be sent.
`flags`	Control the serialization of the data types. Refer to the Boost.Serialization documentation before changing the default flags.
`position`	Set the offset into buffer `b` at which deserialization will begin.

packed_iarchive(MPI_Comm const & comm, std::size_t s = 0, 
                unsigned int flags = boost::archive::no_header);

Construct a packed_iarchive for transmission over the given MPI communicator.

Parameters:

`comm`	The communicator over which this archive will be sent.
`flags`	Control the serialization of the data types. Refer to the Boost.Serialization documentation before changing the default flags.
`s`	The size of the buffer to be received.
