Although you don't say so up front, further down it is evident
that this is a manual page from SGE N1, meaning SGE 6. Thanks.

>From the manpage sge_conf:

qmaster_params
     A list of additional parameters can be passed to the N1 Grid
     Engine qmaster. The following values are recognized:

     ENABLE_FORCED_QDEL
          If this parameter is set, non-administrative users  can
          foce  deletion  of  their own jobs via the -f option of
          qdel(1).  Without this parameter,  forced  deletion  of
          jobs  is  only allowed by the N1 Grid Engine manager or
          operator.

          Note: Forced deletion for jobs is executed  differently
          depending  on whether users are N1 Grid Engine adminis-
          trators or not. In case of  administrative  users,  the
          jobs  are removed from the internal database of N1 Grid
          Engine immediately. For regular users,  the  equivalent
          of  a normal qdel(1) is executed first, and deletion is
          forced only if the normal cancellation  was  unsuccess-
          ful.

Regards,
