SLURM Workload Manager is a queue management system which replaces the commercial LSF scheduler as the job manager on CSUC.
You can use the rosetta stone from SchedMD or take a look below, there is a quick reference table comparing commands between them:
Commands:
| LSF | SLURM | Description |
|---|---|---|
| bsub < example.lsf | sbatch example.slm | Submits a job to he queue system. |
| sbatch --test-only example.slm | Test and find out when your job is estimated to run | |
| bkill <job_id> | scancel <job_id> | Kills the job with the specified ID. |
| bjobs | squeue | List user’s active jobs |
| bqueues | sinfo | Show the partitions (queues) information and the |
| bacct | sacct | Display accounting data |
| interactiu | srun --pty /bin/bash | Obtain a job allocation and execute and application |
Job Environmental Variables:
| LSF | SLURM | Description |
|---|---|---|
| $LSB_JOBID | $SLURM_JOB_ID | Job ID |
| $LSB_SUBCWD | $SLURM_SUBMIT_DIR | Submission directory |
| $LSB_SUB_HOST | $SLURM_SUBMIT_HOST | Submission host |
| $LSB_HOSTS | $SLURM_JOB_NODELIST | Allocated calculation nodes |
| $LSB_DJOB_NUMPROC | $SLURM_NTASKS | Number of processors allocated |
| $SLURM_JOB_PARTITION | Queue |
