MPE_Seq_begin(4) MPE MPE_Seq_begin(4)NAMEMPE_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
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).
