Syntax

int MPIAPI MPI_Finalize(void);

MPI_SUCCESS if the function returns successfully. Other error codes if the call failed for other reasons (such as invalid arguments). In Fortran the return value is stored in the IERROR parameter.

Remarks

All MPI Processes must call this routine before exiting on the thread that called MPI_Init or MPI_Init_thread.

The MPI_Finalize function cleans up all state related to MPI. Once it is called, no other MPI functions may be called, including MPI_Init and MPI_Init_thread. The application must ensure that all pending communications are completed or canceled before calling MPI_Finalize.
