Viewing Host Information
LSF uses some or all of the hosts in a cluster as execution hosts. The host list is
configured by the LSF administrator. Use the
bhosts command to view host
information. Use the
lsload command to view host load information.
Viewing all hosts in the cluster and their status
Run bhosts to display information about all hosts and their status.
bhosts displays condensed information for hosts that belong to condensed host
groups. When displaying members of a condensed host group,
bhosts lists the host
group name instead of the name of the individual host. For example, in a cluster with a
condensed host group (
groupA), an uncondensed host group (groupB containing
hostC and hostE), and a host that is not in any host group (hostF), bhosts displays
the following:
% bhosts
HOST_NAME STATUS JL/U MAX NJOBS RUN SSUSP USUSP RSV
groupA ok 5 8 4 2 0 1 1
hostC ok - 3 0 0 0 0 0
hostE ok 2 4 2 1 0 0 1
hostF ok - 2 1 1 0 1 0
Define condensed host groups in the HostGroups section of lsb.hosts. To find out
more about condensed host groups and to see the configuration for the above example,
see “Defining condensed host groups” on page 120.
Viewing uncondensed host information
Run bhosts -X to display all hosts in an uncondensed format, including those
belonging to condensed host groups.
HOST_NAME STATUS JL/U MAX NJOBS RUN SSUSP USUSP RSV
hostA ok 2 2 0 0 0 0 0
hostD ok 2 4 2 1 0 0 1
hostB ok 1 2 2 1 0 1 0
hostC ok - 3 0 0 0 0 0
hostE ok 2 4 2 1 0 0 1
hostF ok - 2 1 1 0 1 0
