comfortable interactive session, but every job submitted to this queue is executed on the LSF execution host instead of the first allocated node.

Example 7-23shows this subtle difference. Note that the LSF execution host in this example is

7.7 LSF Equivalents of SLURM srun Options

Table 7-2describes the srun options and lists their LSF equivalents.

Table 7-2: LSF Equivalents of SLURM srun Options

srun Option Description LSF Equivalent

-n, --ntasks=ntasks	Number of processes (tasks) to run.
-c, --cpus-per-task=ncpus	Number of CPUs per task. Min CPUs
	per node = MAX(ncpus, mincpus)
-N, --nodes=min[-max]	Minimum and maximum number
	of nodes allocated to job. The
	job allocation will at least contain
	minimum number of nodes.

bsub -n <num>

HP XC does not provide this option because the meaning of this option can be covered by “bsub –n” and “mincpus=n”.

-ext “SLURM[nodes=min[-max]]”

--mincpus=n	Specify minimum number of CPUs	-ext “SLURM[mincpus=n]”
	per node. Min cpus per node =
	MAX(-c ncpus, --mincpus=n).
	Default value is 1.
--mem=MB	Specify a minimum amount of real	-ext “SLURM[mincpus=n]”
	memory of each node. By default,
	job does not require.
--tmp=MB	Specify a minimum amount of	“SLURM[tmp=MB]”
	temporary disk space of each node.
	By default, job does not require -ext.
-C, --constraint=list	Specify a list of constraints. The	-ext “SLURM[constraint=list]”
	list may include multiple features
	separated by “&” or “”. “&”
	represents ANDed, “” represents
	ORed. By default, job does not
	require.
