HOSTGROUP(5) Grid Engine File Formats HOSTGROUP(5)


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 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.


A host group entry contains the following parameters:


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).


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.


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.
