void MPE_Seq_begin( MPI_Comm comm, int ng )
|comm||Communicator to sequentialize.
|ng||Number in group. This many processes are allowed to execute
at the same time. Usually one.
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).
