MPI_Wtime(3) MPI MPI_Wtime(3) NAME MPI_Wtime - Returns an elapsed time on the calling processor SYNOPSIS #include "mpi.h" double MPI_Wtime() RETURN VALUE Time in seconds since an arbitrary time in the past. NOTES This is intended to be a high-resolution, elapsed (or wall) clock. See MPI_WTICK to determine the resolution of MPI_WTIME . If the attribute MPI_WTIME_IS_GLOBAL is defined and true, then the value is synchronized across all processes in MPI_COMM_WORLD . NOTES FOR FORTRAN This is a function, declared as DOUBLE PRECISION MPI_WTIME() in For- tran. SEE ALSO also: MPI_Wtick, MPI_Attr_get LOCATION wtime.c 11/14/2001 MPI_Wtime(3)
