Function Documentation

check_mpi_thread_level()

void ablastr::parallelization::check_mpi_thread_level

(

)

Check if the requested MPI thread level is valid

Prints warnings and notes otherwise.

mpi_finalize()

void ablastr::parallelization::mpi_finalize

(

)

Finalize MPI

This function is simply a wrapper around MPI_Finalize(). It is a no-op if ABLASTR is compiled without MPI support.

mpi_init()

std::pair< int, int > ablastr::parallelization::mpi_init	(	int	argc,
		char *	argv[] )

Initialize MPI

Returns

pair(required, provided) of MPI thread level from MPI_Init_thread

mpi_thread_required()

int ablastr::parallelization::mpi_thread_required ( )

constexpr

Return the required MPI threading

Returns

the MPI_THREAD_* level required for MPI_Init_thread
