The implementation of pushing the required elements for Reduce calls. Might rework for conciseness. Note that we require a separate TAPE_AMPI_push_MPI_Op function to push the reduce operation. I defined _push_MPI_Op in AdjoinableMPI/Tape/support.c w/ header AdjoinableMPI/ampi/tape/support.h.

void* ADTOOL_AMPI_rawAdjointData ( void * activeData)

map active data to adjoint data; this is to be implemented for the backward execution by tools using association-by-address; for tools using association-by-name the same address should be returned;

Returns the diff part of the adjoint of a communication buffer passed to AMPI send or recv. For Tapenade, this is the adjoint communication buffer itself (association by name)

Parameters

ampiRequest is the request instance that is modified

void ADTOOL_AMPI_setBufForAdjoint	(	struct AMPI_Request_S *	ampiRequest,

	)

an operator overloading tool should not do anything in the implementation but see ADTOOL_AMPI_mapBufForAdjoint; a source transformation tool would receive the adjoint buffer as an argument and set it on the request;

Parameters

buf	is the adjoint buffer (for source transformation tools)
ampiRequest	is the request to be used during the adjoint communication
