MPI_Wtime(3) LAM/MPI MPI_Wtime(3)
MPI_Wtime - Returns an elapsed time on the calling processor
Time in seconds since an arbitrary time in the past.
This is intended to be a high-resolution, elapsed (or wall) clock. See MPI_Wtick to determine the resolution of MPI_Wime
. 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 function is declared as DOUBLE PRECISION MPI_WTIME() in Fortran.
For more information, please see the official MPI Forum web site, which contains the text of both the MPI-1 and MPI-2 standards. These
documents contain detailed information about each MPI function (most of which is not duplicated in these man pages).
The LAM Team would like the thank the MPICH Team for the handy program to generate man pages ("doctext" from ftp://ftp.mcs.anl.gov/pub/sow-
ing/sowing.tar.gz ), the initial formatting, and some initial text for most of the MPI-1 man pages.
