Global scalar and data owner

  
Figure: Memory mapping

  on(p) {
    int # s = new int #;
    # s = 100;
  }

  on(p)
    int # s = new int # on q;

  on(q) 
    int # s = new int #;

In the first fragment, the owner of s is set as Group q, but its descriptor is duplicated on each process in Group p where s is defined.
