HP XC System 2.x Software manual Running LSF Jobs with a Slurm Allocation Request

steps through a series of commands that illustrate what occurs when you launch an interactive shell.

Check LSF execution host information:

$ bhosts
HOST_NAME	STATUS JL/U		MAX NJOBS RUN SSUSP USUSP RSV
lsfhost.localdomain	ok	-	12	0	0	0	0	0

Check partition information:

$ sinfo
PARTITION AVAIL		TIMELIMIT	NODES	STATE	NODELIST
lsf	up	infinite	6	idle	n[5-10]

Check local host information:

$ hostname

n2

Check job information:

$ bjobs

No unfinished job found

Run the LSF bsub -Iscommand to launch the interactive shell:

$ 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
JOBID	USER	STAT	QUEUE	FROM_HOST	EXEC_HOST	JOB_NAME	SUBMIT_TIME
120	smith	RUN	normal	n2	lsfhost.loc	/bin/bash	date and time

Note the output when srun hostname is issued:

$ srun hostname

n10

Exit from the shell:

$ exit

exit

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 ...>>

<<Starting on lsfhost.localdomain>> n13

n14
