Ibm Lsf Slots
Existing LSF slot reservation works in simple environments, where the host-based MXJ limit is the only constraint to job slot request. In complex environments, where more than one constraint exists (for example job topology or generic slot limit): Estimated job start time becomes inaccurate.

- LSF with Apache Spark. The IBM Spectrum LSF integration with Apache Spark provides connector scripts that allow users to submit Spark applications as regular LSF jobs. Apache Spark ('Spark') is an in-memory cluster computing system for large-scale data processing.
- Job slot A job slot is a bucket into which a single unit of work is assigned in the LSF system. Hosts can be configured with multiple job slots and you can dispatch jobs from queues until all the job slots are filled. You can correlate job slots with the total number of CPUs in the cluster.
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 If you need to include a hyphen (-) or other non-alphabetic characters within the string, enclose the text in single quotation marks, for example, bsub -R 'select[hname!='host06-x12']'. If the LSF_STRICT_RESREQ=Y parameter is specified in the lsf.conf file, the selection string must conform to the stricter resource requirement string syntax
Is there a way to check the position of my jobs within an LSF queue?
If I run:
bjobs -u all -q my_queue
I get a list of jobs from all users within my_queue, but is this list sorted by the position of my jobs within the queue?

I believe you're interested in pending jobs.
This will show all pending jobs in a queue.
bjobs -u all -p -q my_queue
This list is sorted by position in queue.

The position is based on job priority and submit time.
Keep in mind, what is displayed is not a perfect indication of when a job will run. LSF will start jobs as the correct resources are available. A job requiring a lot of resources may be first in the queue. But if the required resources are not available, LSF will start other jobs behind it that are within the available resources.
For example, if you use bsub -a “esub1 ($PATH, `ls`)” user_job, the first argument passed to esub1 would be the value of variable PATH , and the second Job slot limits. Job slot limits can correspond to the maximum number of jobs that can run at any point in time. For example, a queue cannot start jobs if it has no job slots available, and jobs cannot run on hosts that have no available job slots.
To check progress on individual job -

This command sort of creates an output stream where the job redirects it's output.

For each host used by the pool, define a maximum job slot limit, either in lsb.hosts (MXJ) or lsb.resources (HOSTS and SLOTS). Configure two pools. The following 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. LSF was based on the Utopia research project at the University of Toronto.

When you submit a job to LSF Batch, it may be held in the queue before it starts You can use this command to check if your job is behaving as you expected the element with index 5 in the job array with ID 212 to the first queuing position.

#BSUB -n 1 asks LSF for one CPU core. You can check on the status of your job since it was submitted. The bhist command displays a summary of the pending, suspended, and running time of jobs for the user who invoked the command.
