Table 9-2 LSF-HPC Equivalents of SLURM srun Options

srun Option

-n

--ntasks=ntasks

-c

--processors-per-task=ntasks

-N

--nodes=min[-max]

Description

Number of processes (tasks) to run.

Specifies the number of cores per task. Min processors per node = MAX(ncpus, mincpus)

Specifies the minimum and, optionally, maximum number of nodes allocated to job. The job allocation will contain at least the minimum number of nodes.

LSF-HPC Equivalent

bsub -n num

HP XC does not provide this option because the meaning of this option can be covered by bsub -nand mincpus=n.

-ext "SLURM[nodes=minmax]"

where minmax is min[-max]

--mincpus=n	Specifies the minimum number of cores per	-ext "SLURM[mincpus=n]"
	node. Min processors per node = MAX(-c
	ncpus, --mincpus=n). Default value is 1.
--mem=MB	Specifies a minimum amount of real memory	-ext "SLURM[mem=MB]"
	of each node. By default, job does not
	require -ext.
--tmp=MB	Specifies a minimum amount of temporary	-ext "SLURM[tmp=MB]"
	disk space of each node. By default, job
	does not require -ext.

-C

--constraint=list

Specifies a list of constraints. The list may	-ext "SLURM[constraint=list]"
include multiple features separated by the &
character (meaning ANDed) or the
(meaning ORed). By default, job does not
require -ext.

-w

--nodelist=node1,...nodeN

-x

--exclude=node1,...nodeN

Requests a specific list of nodes. The job will -ext "SLURM[nodelist=node1,...nodeN]" at least contain these nodes. The list may be

specified as a comma-separated list of nodes, or a range of nodes. By default, job does not require -ext.

Requests that a specific list of hosts be -ext "SLURM[exclude=node1,...nodeN]" excluded in the resource allocated to this

job. By default, job does not require.

-p

--partition=partition

--contiguous

Requests resources from partition	You cannot use this option. The lsf partition
partition.	is the only one provided.
Requests a contiguous range of nodes. By	-ext "SLURM[contiguous=yes]"
default, job does not require contiguous
nodes.

-o	Specifies the mode for stdout redirection.	bsub -ooutput_file
--output=file_name
-o	Specify the mode for stdout redirection.	You can use this option when launching parallel tasks.
--output=none,tasked
-i	Specify how stdin is to be redirected.	bsub -iinput_file
--input=file_name
-i	Specify how stdin is to be redirected.	You can use when launching parallel tasks.
--input=none,tasked
-e	Specify how stderr is to be redirected.	bsub -eerror_file
--error=file_name
-e	Specify how stderr is to be redirected.	You can use when launching parallel tasks.
--error=none,tasked
-J	Specify a name for the job.	You cannot use this option. When creating allocation.
--job-name=job_name		SLURM sets LSF-HPC job id automatically.
