What about,

(defun my/eval-parent-subtree()
  (save-excursion
    (outline-up-heading 1)
    (org-babel-execute-subtree)))

And then binding that to some key or something? Or (outline-up-heading 99) if you always want to go to "*". Or make that line a bit more dynamically controllable by use of 'prefix-arg' ?

  -k.
