A.3 Running LSF Jobs with a SLURM Allocation Request

A.3.1 Example 1. Two Processors on Any Two Nodes

This example submits a job that requests two processors 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 ...>>
