MPI_ISend_params()

std::pair< size_t *, char * > MPI_ISend_params	(	Param_t	params,
		size_t	pid,
		MPI_Comm	comm,
		MPI_Request *	req
	)

Serializes a parameter list and asynchronously sends (MPI) to another processor. The memory associated with returned buffers must be freed by the consumer.

Parameters

params	parameter list to serialize
pid	processor ID to send data to
comm	MPI communicator group used for sending the data
req	MPI request assigned with the ISend

MPI_Recv_params()

void MPI_Recv_params	(	Param_t &	params,
		size_t	pid,
		MPI_Comm	comm
	)

Receives and unpacks a parameter list from another (MPI) processor.

Parameters

params	parameter list to store data
pid	processor ID to receive data from
comm	MPI communicator group used for receiving the data
