MPI_T_finalize

:ref:`MPI_T_finalize` |mdash| Finalize the MPI tool information interface

SYNTAX

C Syntax

#include <mpi.h>

int MPI_T_finalize(void)

DESCRIPTION

MPI_T_finalize() finalizes the MPI tool information interface and must be called the same number of times as MPI_T_init_thread() by the end of execution. Calls to MPI tool functions are allowed at any point in execution as long as MPI_T_init_thread() has been called at least once and the number of calls to MPI_T_init_thread() is greater than the number of calls to MPI_T_finalize(). If at any point in execution the number of calls to MPI_T_finalize() equals the number of calls to MPI_T_init_thread() the MPI tool interface will no longer be available until another call to MPI_T_init_thread().

NOTES

Before the end of execution the number of calls to MPI_T_init_thread() and :ref:`MPI_T_finalize` must be the same.

ERRORS

:ref:`MPI_T_finalize` will fail if:

  • MPI_T_ERR_NOT_INITIALIZED: The MPI Tools interface not initialized
.. seealso::
   * :ref:`MPI_T_init_thread`
