[Pw_forum] Simple question on parallel IO

[H. Lee]

Dear all:

I have a simple question on parallel IO in QE.
In many subroutines, "write" statement is used without the restriction to
ionode.
For example, in c_bands.f90,

...

  avg_iter = avg_iter / nkstot

  !



  WRITE( stdout, &

       '( 5X,"ethr = ",1PE9.2,",  avg # of iterations =",0PF5.1 )' ) &

       ethr, avg_iter

  !



  CALL stop_clock( 'c_bands' )

  !



  RETURN

  !



END SUBROUTINE c_bands

Then, why is not this message printed duplicately for using the cores more
than one?

Regards.

H. Lee
