NOTES

       This  function  is  deprecated.  It has been replaced with an MPI-2 function (see the "See
       also" section, below), which provides  the  same  functionality.   This  function  is  (or
       effectively  is)  a wrapper to the replacement function, anyway.  User programs should use
       the MPI-2 replacement function instead of this function.

       Some functions are deprecated because their names did not conform to the  stricter  naming
       conventions  of  MPI-2;  others  are  deprecated because they have been replaced with more
       flexible functionality.

MORE INFORMATION

       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).

ACKNOWLEDGEMENTS

       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/sowing/sowing.tar.gz  ),  the  initial
       formatting, and some initial text for most of the MPI-1 man pages.
