NAME

       MPE_Seq_begin -  Begins a sequential section of code.

SYNOPSIS

       void MPE_Seq_begin( MPI_Comm comm, int ng )

INPUT PARAMETERS

       comm   - Communicator to sequentialize.
       ng     -  Number  in group.  This many processes are allowed to execute
              at the same time.  Usually one.

NOTES

       MPE_Seq_begin and MPE_Seq_end provide a way to force a section of  code
       to be executed by the processes in rank order.  Typically, this is done
       with
       MPE_Seq_begin( comm, 1 );
       <code to be executed sequentially>
       MPE_Seq_end( comm, 1 );

       Often, the sequential code contains output statements (e.g.,  printf  )
       to be executed.  Note that you may need to flush the I/O buffers before
       calling MPE_Seq_end ; also note that some systems do not propagate  I/O
       in  any  order  to the controling terminal (in other words, even if you
       flush the output, you may not get the data in the order that you want).
