Functions
template<typename T >
std::vector< T >	walberla::mpi::gatherv (const std::vector< T > &values, int recvRank=0, MPI_Comm comm=MPI_COMM_WORLD)
	Gathers values from MPI processes and stores them into a std::vector. More...
template<>
std::vector< std::string >	walberla::mpi::gatherv (const std::vector< std::string > &values, int recvRank, MPI_Comm comm)
template<typename T >
std::vector< T >	walberla::mpi::allGatherv (const std::vector< T > &values, MPI_Comm comm=MPI_COMM_WORLD)
	Gathers values from MPI processes and stores them into a std::vector on all Processes. More...
template<>
std::vector< std::string >	walberla::mpi::allGatherv (const std::vector< std::string > &values, MPI_Comm comm)
void	walberla::mpi::gathervBuffer (const mpi::SendBuffer &sendBuffer, mpi::RecvBuffer &recvBuffer, int targetRank=0, MPI_Comm comm=MPI_COMM_WORLD)
	Gathers the buffer content on a single target process. More...
void	walberla::mpi::allGathervBuffer (const mpi::SendBuffer &sendBuffer, mpi::RecvBuffer &recvBuffer, MPI_Comm comm=MPI_COMM_WORLD)
	Almost identical to mpi::gathervBuffer, the only difference: The result is stored on every process. More...
