Function Documentation

ghost_error ghost_finalize

(

)

Finalize GHOST.

Returns

GHOST_SUCCESS on success or an error indicator.

Finalization includes:

• Wait for all outstanding tasks to finish with ghost_taskq_waitall()
• Destroy the Task queue with ghost_taskq_destroy()
• Destroy the thread pool with ghost_thpool_destroy()
• Destroy the PU map with ghost_pumap_destroy()
• Destroy the machine topology
• Call MPI_Finalize() if MPI_Init() has been called by GHOST
• Destroy the random number states
• Destroy the MPI operations and data types

Parameters

argc	argc as it has been passed to main() (needed for MPI_Init()).
argv	argv as it has been passed to main() (needed for MPI_Init()).

Returns

GHOST_SUCCESS on success or an error indicator.

Here is the call graph for this function:

int ghost_initialized

(

)

Check if GHOST is initialized.
