HP XC System 2.x Software - Manual (Page 92)

The following example shows the output from the bhosts command:
$ bhosts
HOST_NAME STATUS JL/U MAX NJOBS RUN SSUSP USUSP RSV
lsfhost.localdomain ok - 16 0 0 0 0 0
Of note in the bhosts output:
• The HOST_NAME column displays the name of the LSF execution host.
• The MAX column displays the total processor count (usable CPUs) of all available computer
nodes in the lsf partition.
• The STATUS column shows the state of LSF and displays a status of either ok or closed .
• The NJOBS column displays the number of jobs.
7.3.2 Getting Information About LSF-HPC Execution Host Node
The lshosts command displays resource information about the LSF-HPC execution host
node. This command is useful for checking machine-specific information.
LSF daemons run on only one node in the HP XC system, so the lshosts command will
list one host — which represents all the resources of the HP XC system. The total number
of processors for that host should be equal to the total number of processors assigned to the
SLURM
lsf partition.
By default, lshosts returns the following information: host name, host type, host model, CPU
factor, number of CPUs, total memory, total swap space, server information, and static resources.
The following example shows the output from the lshosts command:
$ lshosts
HOST_NAME type model cpuf ncpus maxmem maxswp server RESOURCES
lsfhost.loc SLINUX6 Itanium2 16.0 12 3456M - Yes (slurm)
n7 UNKNOWN UNKNOWN_ 1.0 - - - No ()
n8 UNKNOWN UNKNOWN_ 1.0 - - - No ()
n2 UNKNOWN UNKNOWN_ 1.0 - - - No ()
Of note in the lshosts output:
• The HOST_NAME column displays the name of the LSF-HPC execution host,
lsfhost.localdomain and any other HP XC nodes that have been granted a floating
client license because LSF commands were executed on them. LSF-HPC does not know
about these floating client hosts, so they are listed as
UNKNOWN types and models.
• The ncpus column displays the total processor count (usable CPUs) of all available
computer nodes in the lsf partition.
• The maxmem column displays minimum maxmem over all available computer nodes in
the lsf partition.
• The maxtmp column (not shown) displays minimum maxtmp over all available computer
nodes in the lsf partition. Use the lshosts -l command to display this column.
7.3.3 Getting Host Load Information
The LSF lsload command displays load information for LSF execution hosts.
$ lsload
HOST_NAME status r15s r1m r15m ut pg ls it tmp swp mem
lsfhost.loc ok - - - - - 4 - - - -
In the previous example output, the LSF execution host ( lsfhost.localdomain ) is listed
under the HOST_NAME column. The status is listed as ok , indicating that it can accept
remote jobs. The ls column shows the number of current login users on this host.
