HP XC System 2.x Software manual Getting Information About LSF-HPC Execution Host Node

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.

7.3.2Getting 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 -lcommand to display this column.

7.3.3Getting 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.
