Detailed Description

send data packed by CharPack.

NAME: CharPackMPI - send data packed by CharPack

DESCRIPTION:

The class enables packing and communication of data, useful in parallel/distributed programming. Currently the class only implements blocking send and receive. CharPack'ed arrays can easily be distributed non-blocking by making explicit calls to non-blocking MPI-routines.

Constructor & Destructor Documentation

CharPackMPI::CharPackMPI ( ) [inline]

One must know the upper limit of the char array (the number of bytes to be packed) when creating a "CharPackMPI" object. Hopefully, the programmer is able to compute this length exactly.

Member Function Documentation

void CharPackMPI::initiateRecv ( int & length, int source, int tag, MPI_Comm comm = MPI_COMM_WORLD )

set up communication by receiving the size of the packed array to be sent using function "send"

void CharPackMPI::initiateSend ( int dest, int tag, MPI_Comm comm = MPI_COMM_WORLD )

set up communication by sending the size of the packed array to be sent using function "send"

void CharPackMPI::receive ( int length, int source, int tag, MPI_Comm comm = MPI_COMM_WORLD )

void CharPackMPI::send ( int dest, int tag, MPI_Comm comm = MPI_COMM_WORLD )
