NAME
MPI_Wtick - Returns the resolution of MPI_Wtime
SYNOPSIS
#ifdef ENABLE_QMPI #ifndef MPICH_MPI_FROM_PMPI double QMPI_Wtick(QMPI_Context context, int tool_id) MPICH_API_PUBLIC
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 Fortran.
