Function Documentation

xt_xmap_dist_dir_intercomm_new()

Xt_xmap xt_xmap_dist_dir_intercomm_new	(	Xt_idxlist	src_idxlist,
		Xt_idxlist	dst_idxlist,
		MPI_Comm	inter_comm,
		MPI_Comm	intra_comm
	)

Construct an exchange map over an intercommunicator
This operation is collective over all processes in comm.
It uses a distributed directory for the initialisation

Parameters

[in]	src_idxlist	source index list
[in]	dst_idxlist	destination index list
[in]	inter_comm	MPI intercommunicator that contains all processes that part in the exchange (xt_xmap_dist_dir_icomm_new will make its own copy of comm)
[in]	intra_comm	MPI intracommunicator corresponding to the group of inter_comm that the calling rank belongs to

Examples:

test_xmap_dist_dir_intercomm_parallel.c.
