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  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 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.
