Function Documentation

mpi_handshake()

void mpi_handshake	(	char const **	group_names,
		MPI_Comm *	group_comms,
		size_t	n,
		MPI_Comm	comm )

Parameters

[in]	group_names	names of process groups
[out]	group_comms	MPI communicators containing all processes that provided the same group names
[in]	n	number of group names
[in]	comm	MPI communicator used for the splitting

Remarks

this call is collective for all processes in comm (if no splitting is required by the local processes mo_mpi_handshake::mpi_handshake_dummy can be called instead)
