HP XC System Software Administration Guide Version 3.2

Alternatively, you can invoke the following command to start LSF-HPC with SLURM on the
current node:
# controllsf start here
16.5.2 Shutting Down LSF-HPC with SLURM
At system shutdown, the /etc/init.d/lsf script ensures an orderly shutdown of LSF-HPC
with SLURM.
You can use the controllsf command, as shown here, to stop LSF-HPC with SLURM regardless
of where it is active in the HP XC system:
# controllsf stop
16.6 Controlling the LSF-HPC with SLURM Service
You can use the service command to start or stop the LSF-HPC with SLURM service on the
HP XC system, or to obtain the system's current status:
• service lsf start
This command is primarily of interest for automated startup. If the current node is the
primary LSF execution host, it sets the state to RUNNING, then starts LSF-HPC with SLURM
unless it is already running somewhere on the HP XC system. If the node is not the primary
LSF execution host, it ignores the command.
• service lsf stop
This command stops the LSF-HPC with SLURM environment if it is running on the current
node.
Invoking this command on the LSF execution host or on the head node shuts down the
LSF-HPC with SLURM environment regardless where it is on the HP XC system, and sets
the state to SHUT DOWN to prevent any attempt to fail over the LSF-HPC with SLURM service
to another node.
• service lsf status
This command reports the current state (UP or DOWN) of LSF-HPC with SLURM.
This command has the same function as controllsf status.
16.7 Launching Jobs with LSF-HPC with SLURM
You may not submit LSF-HPC with SLURM jobs as superuser (root). You may find it convenient
to run jobs as the local lsfadmin user. An example would be a job to test a new queue
configuration.
The LSF-HPC with SLURM daemons run on one node only: the LSF execution host. Therefore,
they can dispatch jobs only on that node. The JOB_STARTER script, described in “Job Starter
Scripts” (page 192), ensures that user jobs execute on their reserved nodes, and that these jobs do
not contend for the LSF execution host.
Consider an HP XC system in which node n120 is the LSF execution host, and nodes n1 through
n99 are compute nodes. The following series of examples shows jobs launched without the
JOB_STARTER script with varied results.
Example 16-3 illustrates the launching of a job in its most basic form.
