hostgroup(5)
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 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.
FORMAT
- A host group entry contains 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 name of all hosts and host groups (see host_identifier in sge_types(1)) which are member of the group. As list separators whitespaces 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 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.
