Working with Hosts
You cannot define subgroups that contain wildcards and special characters. The
following definition for
groupB is not correct because groupA defines hosts with a
wildcard:
Begin HostGroup
GROUP_NAME GROUP_MEMBER
groupA (hostA*)
groupB (groupA)
End HostGroup
Defining condensed host groups
You can define condensed host groups to display information for its hosts as a
summary for the entire group. This is useful because it allows you to see the total
statistics of the host group as a whole instead of having to add up the data yourself.
This allows you to better plan the distribution of jobs submitted to the hosts and
host groups in your cluster.
To define condensed host groups, add a CONDENSE column to the
HostGroup
section. Under this column, enter
Y to define a condensed host group or N to define
an uncondensed host group, as shown in the following:
Begin HostGroup
GROUP_NAME CONDENSE GROUP_MEMBER
groupA Y (hostA hostB hostD)
groupB N (hostC hostE)
End HostGroup
The following commands display condensed host group information:
◆ bhosts
◆ bhosts -w
◆ bjobs
◆ bjobs -w
For the
bhosts output of this configuration, see Viewing Host Information on page
62.
Use
bmgroup -l to see whether host groups are condensed or not.
Hosts belonging to multiple condensed host groups
If you configure a host to belong to more than one condensed host group using
wildcards,
bjobs can display any of the host groups as execution host name.
For example, host groups
hg1 and hg2 include the same hosts:
Begin HostGroup
GROUP_NAME CONDENSE GROUP_MEMBER # Key words
hg1 Y (host*)
hg2 Y (hos*)
End HostGroup
Submit jobs using bsub -m:
bsub -m "hg2" sleep 1001
