hostgroup - host group entry file format
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 to 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 enlisted 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, Sun Grid Engine allows backslashes (\) be used to escape newline
(\newline) characters. The backslash and the newline are replaced with
a space (" ") character before any interpretation.
A host group entry contains following parameters:
The group_name defines the host group name. Host group names have to

The name of all hosts and host groups (see host_identifier in
sge_types(1)) which are member of the group. As list separators white-
spaces are supported only. 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 sub group of
This is a typical host group entry:
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.
