SLURM v iews the LSF-HPC system as one large computer with many resources available to
run jobs.
SLURM does not provide the same amount of information that can be obtained via standard
LSF. But on HP XC sy stems, where the compute nodes have the same architecture and
are expected to be allocated solely through LSF on a per-processor or per-node basis, the
information provided by SLURM is sufficient and allows the LSF-HPC design to be more
scalable and generate less overhead on the compute nodes.
Integrating LSF-HPC with SLURM on HP XC systems also provides you w ith a parallel launch
command to di stribut e and manage parall el tasks efficiently. The S L URM srun command
offers much flexibility in requesti ng topological requirements across an HP XC system, such
as requesting contiguous no des or executing only one t ask per node, or requesting no des with
specific features. This flexibility is preserved in LSF-HPC through the external SLURM
scheduler; this is discussed in more detail in Section 7.1.2.
In an HP XC system, only o ne node runs LSF-HPC, but all no des in the are configured as
LSF-HPC Client Hosts; this means that every node is able to access LSF-HPC. You can submit
jobs from any node i n the HP XC system.
See Section 7.1.5 and the lsf_diff
(1) manpage for more information on the subtle
differences between standard LSF and LSF-HPC. Differences described in HP XC System
Software documentation take precedence over d escriptions in the LSF docum e ntation from
Platform Computing Corporation.
7.1.2 Topology Support
LSF-HPC contains topolo gy support when requesting resources for a job. This topology support
is available throu gh LSF’s standard ex ternal scheduler feature, which makes use of a SLURM
external scheduler provided with LSF- HPC on HP XC System Software systems.
Section 1.4.3 describes the interaction of SLURM and LSF-HPC on HP XC System Software
systems.
You can apply LSF-H PC’s external scheduler functionali ty with the bsub command and in LSF
queue configurations. See the L SF bqueues
(1) command for more information on determining
how t he available queues are configured on HP XC System Software systems. The format of
the LSF bsub command with the external SLURM scheduler option is:
bsub -ext "SLURM[slurm-arguments]" [bsub-options] jobname [job-options]
The slurm-arguments parameter can be one or more of the following srun options, separated
by semicolons:
• nodes=min [-max]
• mincpus= ncpus
• mem=value in Megabytes
• tmp=value in Megabytes
• constraint=’feature’
• nodelist= list-of-nodes
• exclude= list-of-nodes
• contiguous=yes
mem=value tmp=value constraint=value nodelist=list-of-nodes
exclude=list-of-nodes contiguous=yes
The srun
(1) manp age provides details on these options and t heir arguments.
