Example 5-14 Submitting a Job Script

Hello world! I'm 0 of 4 on n2
Hello world! I'm 1 of 4 on n2
Hello world! I'm 2 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).
Example 5-15 Submitting a Batch Script with the LSF-SLURM External Scheduler Option
$ bsub -n4 -ext "SLURM[nodes=4]" -I ./myscript.sh
Job <79> is submitted to default queue .

Hello world! I'm 1 of 4 on n2
Hello world! I'm 2 of 4 on n3

Example 5-16 and Example 5-17 show how the jobs inside the script can be manipulated within the
allocation.
Example 5-16 Submitting a Batch Job Script That Uses a Subset of the Allocation
$ bsub -n4 -ext "SLURM[nodes=4]" -I ./myscript.sh
