Submitting a Serial Job Using LSF-HPC
There are various methods for submitting a serial job on the HP XC system:
•
Using the LSF bsub command alone.
•
Using the LSF bsub command in conjunction with the SLURM srun command.
•
Using the LSF bsub command in conjunction with the SLURM srun command and the LSF-SLURM
External Scheduler.
•
Using the SLURM srun command alone.
These methods are explored in this section.
For most instances, the recommended method for submitting a job is to use the LSF bsub command in
conjunction with the SLURM srun command.
Submitting a Serial Job with the LSF bsub Command
Use the bsub command to submit a serial job on the LSF execution host using the following format:
bsub [bsub-options ] [ srun [srun-options]] jobname [job-options]
The bsub command launches the job.
Use the bsub command's -I option to launch an interactive serial job.
The srun command is only necessary to launch the job on the allocated node if the HP XC JOB STARTER
script is not configured. to run a job on the compute nodes in the lsf partition.
The jobname argument is the name of an executable file.
The SLURM srun job launch command is only needed if the LSF-HPC JOB_STARTER script is not configured
for the intended queue, but it can be used regardless of whether or not the script is configured. You can use
the bqueues command to confirm whether or not the JOB_STARTER script exists; see
"Notes on LSF-HPC"
for information on the bqueues command.
Example 5-2 shows the submission and launch of a serial interactive job and its output.
