$ bsub -Is -n1 /bin/bash
Job <120> is submitted to default queue <normal>.
<<Waiting for dispatch ...>>
<<Starting on lsfhost.localdomain>>
Note the output when hostname is again issued:
$ hostname
n16
Note the FROM_HOST when bjobs is again issued:
$ bjobs

Running LSF-HPC Jobs with a SLURM Allocation Request
Example 1. Two cores on Any Two Nodes
This example submits a job that requests two cores on any two nodes, on an HP XC system that has three
compute nodes.
Submit the job:
$ bsub -n2 -ext "SLURM[nodes=2]" -I srun hostname
Job <8> is submitted to default queue <normal>.
<<Waiting for dispatch ...>>
<<Starting on lsfhost.localdomain>>
n13
n14
View the job:
$ bjobs -l 8
