NAME

6       hostgroup - host group entry file format
7

DESCRIPTION

9       A  host  group entry is used to merge host names to groups.  Each  host
10       group  entry  file defines one group. Inside a  group  definition  file
11       you  can also reference to groups. These groups are called subgroups. A
12       subgroup is referenced by the sign "@" as first character of the name.
13
14       A list of currently configured host group entries can be displayed  via
15       the  qconf(1)  -shgrpl option. The contents of each enlisted host group
16       entry can be shown via the -shgrp switch. The output follows the  host‐
17       group  format  description.  New  host group entries can be created and
18       existing can be modified via the  -ahgrp,  -mhgrp,  -dhgrp  and  -?attr
19       options to qconf(1).
20
21       Note,  Grid  Engine  allows  backslashes  (\) be used to escape newline
22       (\newline) characters. The backslash and the newline are replaced  with
23       a space (" ") character before any interpretation.

FORMAT

26       A host group entry contains following parameters:
27
28   group_name
29       The  group_name  defines  the host group name. Host group names have to
30       begin  with  an  '@'  character  as  explained  for  hostgroup_name  in
31       sge_types(5).
32
33   hostlist
34       The  name  of  all  hosts  and  host  groups  (see  host_identifier  in
35       sge_types(1)) which are member of the group. As list separators  white-
36       spaces are supported only. Default value for this parameter is NONE.
37
38       Note,  if the first character of the host_identifier is an "@" sign the
39       name is used to reference a hostgroup(5) which is taken as sub group of
40       this group.

EXAMPLE

44       This is a typical host group entry:
45
46
47       group_name @bigMachines
48
49       hostlist @solaris64 @solaris32 fangorn balrog
50
51       The  entry  will  define  a new host group called @bigMachines. In this
52       host group are the host fangorn, balrog and all  members  of  the  host
53       groups @solaris64 and @solaris32.
