I have been using termios.h to detect a keypress and then deal with it
inside of a loop and when porting it over to mpi, and using mpirun it now
will wait and the loop is paused waiting for a carrige return checking for a
keypress.

I then tried ncurses with nodelay() function and the loop continues but
still requires a return before it deals with the input inside of mpirun.
Where alone it would respond to a keypress without a return.

Both methods above are contained within if( rank == 0 ) { } and in a for(;;)

And I am using svn checkout of OpenMPI.

I would like to be able to press a key within a loop in main to change
values and exit the loop. Very easy with both methods above. But mpirun
seems to alter the behavior.

Do any of you know of a method to acomplish this within an mpi application.
I want to loop forever and respong to keyboard input when it comes in or
shortly there after.
