Function Documentation

xt_redist_single_array_base_new()

Xt_redist xt_redist_single_array_base_new	(	int	nsend,
		int	nrecv,
		struct Xt_redist_msg *	send_msgs,
		struct Xt_redist_msg *	recv_msgs,
		MPI_Comm	comm
	)

constructor for a redistribution using point to point communication for the exchange

Parameters

[in]	nsend	number of send messages
[in]	nrecv	number of receive messages
[in]	send_msgs	array with send messages
[in]	recv_msgs	array with receive messages
[in]	comm	MPI communicator that is to be used for the communication

Remarks

The send_msgs and recv_msgs arrays will be used directly without copying them and must be malloc'ed therefore. When the destructor xt_redist_delete is called, the arrays, the associated MPI data types, and the MPI communicator will be free'd via free(), MPI_Type_free() and MPI_Comm_free() respectively.
