xt_xmap_all2all_custom_new()

Xt_xmap xt_xmap_all2all_custom_new	(	Xt_idxlist	src_idxlist,
		Xt_idxlist	dst_idxlist,
		MPI_Comm	comm,
		Xt_config	config
	)

constructor for an exchange map with custom parameters
this operation is collective over all processes in comm
it uses all-to-all communication for the initialisation

Parameters

[in]	src_idxlist	source index list
[in]	dst_idxlist	destination index list
[in]	comm	MPI communicator that contains all processes that take part in the exchange (xt_xmap_all2all_new will make its own copy of comm)
[in]	config	custom parameters
