LSF Version 7.3 - Platform LSF Configuration Reference

1.6 or the pg index goes above 20. HostA only accepts batch jobs from 19:00 on Friday evening
until 8:30 Monday morning and overnight from 20:00 to 8:30 on all other days.
For hosts of type SUNSOL, the pg index does not have host-specific thresholds and such hosts
are only available overnight from 23:00 to 8:00.
The entry with host name default applies to each of the other hosts in the cluster. Each host
can run up to two jobs at the same time, with at most one job from each user. These hosts are
available to run jobs at all times. Jobs may be started if the r1m index is below 0.6 and the pg
index is below 20, and a job from the lowest priority queue is suspended if r1m goes above 1.6
or pg goes above 40.
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.
