HostGroup Section
Description
Optional. Defines host groups.
The name of the host group can then be used in other host group, host partition, and
queue definitions, as well as on the command line. Specifying the name of a host group
has exactly the same effect as listing the names of all the hosts in the group.
Structure
Host groups are specified in the same format as user groups in lsb.users.
The first line consists of two mandatory keywords, GROUP_NAME and
GROUP_MEMBER, and an optional keyword, CONDENSE. Subsequent lines name
a group and list its membership.
The sum of host groups and host partitions cannot be more than MAX_GROUPS (see
lsbatch.h for details).
GROUP_NAME
Description
An alphanumeric string representing the name of the host group.
You cannot use the reserved name
all, and group names must not conflict with host
names.
CONDENSE
Description
Optional. Defines condensed host groups.
Condensed host groups are displayed in a condensed output format for the
bhosts and
bjobs commands.
If you configure a host to belong to more than one condensed host groups using
wildcards,
bjobs can display any of the host groups as execution host name.
Valid Values
Y
or N.
Default
N
. The specified host group is not condensed.
GROUP_MEMBER
Description
A space-delimited list of host names or previously defined host group names, enclosed
in one pair of parentheses.
You cannot use more than one pair of parentheses to define the list.
The names of hosts and host groups can appear on multiple lines because hosts can
belong to multiple groups. The reserved name
all specifies all hosts in the cluster. Use
an exclamation mark (
!) to specify that the group membership should be retrieved via
egroup.
Pattern definition
You can use string literals and special characters when defining host group members.
Each entry cannot contain any spaces, as the list itself is space delimited.
