This was bounced back to me, so I am trying again...
--Jeff Mullen NCSU Physics Greetings, I have added a subroutine to phonon.f90 which I only want to execute on ionode after elpsum(). I call the routine only on ionode and then call mp_barrier() to sync the processors. Until the call to mp_barrier, it works. The code only runs on the ionode and other processors do not attempt to perform any tasks. The problem is mp_barrier() doesn't "release" after the completion of the subroutine. I thought that mp_barrier() blocked until every operating processor entered mp_barrier, then it stopped blocking and allowed proper program flow. What am I doing wrong?
