comfortable interactive session, but every job submitted to this queue is executed on the LSF
execution host instead of the first allocated node.
Example 7-23 shows this subtle difference. Note that the LSF execution host in this example is
n20 :

7.7 LSF Equivalents of SLURM srun Options
Table 7-2 describes 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. bsub -n <num>
-c, --cpus-per-task=ncpus Number of CPUs per task. Min CPUs
per node = MAX(ncpus, mincpus) HP XC does not provide this option because
the meaning of this option can be covered by
“bsub –n” and “mincpus=n”.
-N, --nodes=min[-max] Minimum and maximum number
of nodes allocated to job. The
job allocation will at least contain
minimum number of nodes. -ext “SLURM[nodes=min[-max]]”
--mincpus=n Specify minimum number of CPUs
per node. Min cpus per node =
MAX(-c ncpus, --mincpus=n).
Default value is 1. -ext “SLURM[mincpus=n]”
--mem=MB Specify a minimum amount of real
memory of each node. By default,
job does not require. -ext “SLURM[mincpus=n]”
--tmp=MB Specify a minimum amount of
temporary disk space of each node.
By default, job does not require -ext. “SLURM[tmp=MB]”
-C, --constraint=list Specify a list of constraints. The
list may include multiple features
separated by “&” or “|”. “&”
represents ANDed, “|” represents
ORed. By default, job does not
require. -ext “SLURM[constraint=list]”
