Example 5-13 Using the External Scheduler to Constrain Launching to Nodes with a Given Feature
$ bsub -n 10 -ext "SLURM[constraint=dualcore]" -I srun hostname
You can use the bqueues command to determine the SLURM scheduler options that apply to
jobs submitted to a specific LSF-HPC queue, for example:
$ bqueues -l dualcore | grep SLURM
MANDATORY_EXTSCHED: SLURM[constraint=dualcore]
5.4 Submitting a Batch Job or Job Script
Use the following bsub command format to submit a batch job or job script:
bsub -n num-procs [bsub-options] script-name
The -n num-procs parameter, which is required for parallel jobs, specifies the number of cores
the job requests.
The script-name argument is the name of the batch job or script. The script can contain one
or more srun or mpirun commands.
The script will execute once on the first allocated node, and the srun or mpirun commands
within the script will be run on the allocated compute nodes.
In Example 5-14 , a simple script named myscript.sh, which contains two srun commands,
is displayed then submitted.
Example 5-14 Submitting a Job Script
$ cat myscript.sh
#!/bin/sh
srun hostname mpirun -srun hellompi
$ bsub -I -n4 myscript.sh
Job <29> is submitted to default queue .

Hello world! I'm 1 of 4 on n2
Hello world! I'm 2 of 4 on n4
Hello world! I'm 3 of 4 on n4
Example 5-15 runs the same script but uses the LSF-SLURM External Scheduler option to specify
different resources (here, 4 compute nodes).
