LSF is a suite of workload management products. LSF manages, monitors, and analyses the workload for a heterogeneous network of computers.
What is needed to run any job in any LSF cluster?
The combination of host type and CPU speed (CPU factor) of the computer. All hosts of the same relative speed are assigned the same host model. The CPU factor is taken into consideration when jobs are being dispatched. A user account that has permission to submit jobs to the LSF cluster.
How do you use BSUB?
Submitting a job with a job name (bsub -J)
Use bsub -J job_name to submit a job and assign a job name to it. You can later use the job name to identify the job. The job name need not be unique. You can also assign a job name to a job array.
What is an LSF cluster?
What is an LSF Cluster? A group of computers (hosts) running LSF that work together as a single unit, combining computing power and sharing workload and resources. A cluster provides a single-system image for disparate computing resources. Hosts can be grouped into clusters in a number of ways.

LSF (Low Smoke & Fume) Cables
LSF cables are usually made up of a modified PVC compound which produces somewhat less HCL gas and smoke on burning than PVC. However, it still produces 15% to 22 % (depending on quality) of HCL gas and due to the presence of PVC can still emit dense black smoke.
What are LSF commands?
User commands
| Command | Description |
|---|---|
| busers | Displays information about users and user groups |
| lshosts | Displays hosts and their static resource information |
| lsid | Displays the current LSF version number, cluster name, and management host name |
| lsinfo | Displays load-sharing configuration information |
How do I submit a job to a cluster?
In order to submit work to the cluster we must first put together a job script which tells Slurm what resources you require for your application. In addition to resources, we need to tell Slurm what command or application to run. A SLURM job script is a bash shell script with special comments starting with “#SBATCH”.
