Macro Definition Documentation

◆ MPI_THREAD_STRING

#define MPI_THREAD_STRING ( level )

Value:

        ( level==MPI_THREAD_SERIALIZED ? "THREAD_SERIALIZED" : \
            ( level==MPI_THREAD_MULTIPLE ? "THREAD_MULTIPLE" : \
                ( level==MPI_THREAD_FUNNELED ? "THREAD_FUNNELED" : \
                    ( level==MPI_THREAD_SINGLE ? "THREAD_SINGLE" : "THREAD_UNKNOWN" ) ) ) )

String description of the MPI thread level.

Parameters

[in] level The MPI thread level.

Returns: A string description of the thread level.

Variable Documentation

◆ own_mpi

bool madness::detail::WorldMpi::own_mpi = false

staticprivate

Flag storing if MADNESS is responsible for MPI.

Todo:: Brief description needed.

Todo:: Verify the above brief description.

◆ world_mpi

std::shared_ptr< WorldMpi > madness::detail::WorldMpi::world_mpi

staticprivate

Pointer to help MADNESS manage MPI.

This shared pointer is used to manage the lifetime of the MPI within MADNESS. It ensures that MPI is destroyed only after the last world object is destroyed.

Referenced by madness::detail::WorldMpi::finalize(), and madness::detail::WorldMpi::initialize().
