void cf3::common::PE::detail::all_gatherc_impl	(	const Communicator &	comm,
		const T *	in_values,
		const int	in_n,
		T *	out_values,
		const int	stride
	)

inline

Implementation to the all_gather interface with constant size communication. Don't call this function directly, use MPI::all_gather instead. In_values and out_values must be linear in memory and their sizes should be #processes*n.

Parameters

comm	Comm::Communicator
in_values	pointer to the send buffer
in_n	size of the send array (number of items)
out_values	pointer to the receive buffer
stride	is the number of items of type T forming one array element, for example if communicating coordinates together, then stride==3: X0,Y0,Z0,X1,Y1,Z1,...,Xn-1,Yn-1,Zn-1

Bug:: (in OpenMPI ) MPI_CHECK_RESULT(MPI_Allgather, (const_cast<T*>(in_values), in_n*stride, type, out_buf, in_n*stride, type, comm));

Todo:: check if in later versions it is fixed

inline

Implementation to the all_gather interface with variable size communication through in and out map. Don't call this function directly, use MPI::all_gathervm instead. In_values and out_values must be linear in memory and their sizes should be sum(in_n[i]) and sum(out_n[i]) i=0..#processes-1.

Parameters

comm	Comm::Communicator
in_values	pointer to the send buffer
in_n	array holding send counts of size #processes
in_map	array of size #processes holding the mapping. If zero pointer passed, no mapping on send side.

out_n	array holding receive counts of size #processes. If zero pointer passed, no mapping on receive side.
out_map	array of size #processes holding the mapping
stride	is the number of items of type T forming one array element, for example if communicating coordinates together, then stride==3: X0,Y0,Z0,X1,Y1,Z1,...,Xn-1,Yn-1,Zn-1
