NAME

       hostgroup - host group entry file format

DESCRIPTION

       A host group entry is used to merge host names to groups.  Each  host
       group  entry  file defines one group. Inside a group definition file
       you can also reference groups. These groups are called subgroups. A
       subgroup is referenced by the sign "@" as first character of the name.

       A list of currently-configured host group entries can be displayed via
       the qconf(1) -shgrpl option. The contents of each listed host group
       entry can be shown via the -shgrp switch. The output follows the
       hostgroup format description. New host group entries can be created and
       existing can be modified via the -ahgrp, -mhgrp, -dhgrp and -?attr
       options to qconf(1).

       Note, Grid Engine allows backslashes (\) be used to escape newline
       characters. The backslash and the newline are replaced with a space
       character before any interpretation.

FORMAT

       A host group entry contains the following parameters:

   group_name
       The group_name defines the host group name. Host group names have to
       begin with an '@' character as explained for hostgroup_name in
       sge_types(5).

   hostlist
       The names of all hosts and host groups (see host_identifier in
       sge_types(5)) which are members of the group.  Only whitespace is
       allowed as list separators. The default value for this parameter is
       NONE.

       Note, if the first character of the host_identifier is an "@" sign the
       name is used to reference a hostgroup(5) which is taken as a subgroup
       of this group.

EXAMPLE

       This is a typical host group entry:


       group_name @bigMachines

       hostlist @solaris64 @solaris32 fangorn balrog

       The entry will define a new host group called @bigMachines. In this
       host group are the host fangorn, balrog and all members of the host
       groups @solaris64 and @solaris32.
