on this topic. See the LSF manpages for full information about the commands described in this
section.
The following LSF commands are described in this section:
bjobs “Examining the Status of a Job”
bhist “Viewing the Historical Information for a Job”
10.11.1 Getting Job Allocation Information
Before a job runs, LSF integrated with SLURM allocates SLURM compute nodes based on job
resource requirements.
After LSF integrated with SLURM allocates nodes for a job, it attaches allocation information to
the job.
The bjobs -l command provides job allocation information on running jobs. The bhist -l
command provides job allocation information for a finished job. For details about using these
commands, see the LSF manpages .
A job allocation information string resembles the following:
slurm_id=slurm_jobid;ncpus=slurm_nprocs;slurm_alloc=node_list
This allocation string has the following values:
slurm_id SLURM_JOBID environment variable. This is SLURM allocation ID (Associates
LSF job with SLURM allocated resources.)
ncpus SLURM_NPROCS environment variable. This the actual number of allocated
cores. Under node-level allocation scheduling, this number may be bigger
than what the job requests.)
slurm_alloc A comma separated list of allocated nodes.
LSF integrated with SLURM sets the SLURM_JOBID and SLURM_NPROCS environment variables,
when it starts a job.
Example 10-3 illustrates how to use the the bjobs -l command to obtain job allocation
information about a running job:
