What is LSF and BSUB?
What is LSF and BSUB?
The bsub command is used to submit a batch script to LSF. It is designed to reject the job at submission time if there are requests or constraints that LSF cannot fulfill as specified. This gives the user the opportunity to examine the job request and resubmit it with the necessary corrections.
What is LSF memory?
LSF collects information such as: Total CPU time consumed by all processes in the job. Total resident memory usage in KB of all currently running processes in a job. Total virtual memory usage in KB of all currently running processes in a job.
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 |
What is an LSF run?
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 a network of computing resources. Hosts can be grouped into clusters in a number of ways.
What is LSF in Unix?
Platform Load Sharing Facility (or simply LSF) is a workload management platform, job scheduler, for distributed high performance computing. It can be used to execute batch jobs on networked Unix and Windows systems on many different architectures.[2][3]
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 LSF in HPC?
LSF (Platform Load Sharing Facility) is a Batch-Scheduler. To get an overview of the functionality of a scheduler, go here or to the Scheduling Basics.
What is CPU factor?
CPU factors are used to differentiate the relative speed of different machines. LSF runs jobs on the best possible machines so that response time is minimized. To achieve this, it is important that you define correct CPU factors for each machine model in your cluster.
What is BSUB?
You submit a job with the bsub command. If you do not specify any options, the job is submitted to the default queue configured by the LSF administrator (usually queue normal). For example, if you submit the job my_job without specifying a queue, the job goes to the default queue.
What is LSF queue?
LSF dispatches the job to the best available execution host in the cluster to run that job. Queues implement different job scheduling and control policies.
What is 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.
How do I run a LSF job?
Use two basic commands to run jobs through LSF: bsub submits jobs to the LSF batch scheduler….Run LSF jobs with bsub and lsrun
- Submit batch jobs with bsub.
- Display job status with bjobs.
- Control job execution with bstop, bresume, and bkill.
