Synopsis
double MPI_Wtime(void)Return value
Time in seconds of resolution of MPI_Wtime
Notes for Fortran
This is a function, declared as DOUBLE PRECISION MPI_WTICK in Fortran.
Notes for Fortran
All MPI routines in Fortran (except for 'MPI_WTIME' and 'MPI_WTICK') have an additional argument 'ierr' at the end of the argument list. 'ierr' is an integer and has the same meaning as the return value of the routine in C. In Fortran, MPI routines are subroutines, and are invoked with the 'call' statement.
All MPI objects (e.g., 'MPI_Datatype', 'MPI_Comm') are of type 'INTEGER' in Fortran.
