MPI_T_finalize - Finalize the MPI tool information interface

17.2.357.1. SYNTAX

17.2.357.1.1. C Syntax

#include <mpi.h>

int MPI_T_finalize(void)

17.2.357.2. 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().

17.2.357.3. NOTES

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

17.2.357.4. ERRORS

MPI_T_finalize will fail if:

  • MPI_T_ERR_NOT_INITIALIZED: The MPI Tools interface not initialized
