About Platform LSF
◆ bsub—Submit jobs
Interactive batch
job
A batch job that allows you to interact with the application and still take advantage
of LSF scheduling policies and fault tolerance. All input and output are through the
terminal that you used to type the job submission command.
When you submit an interactive job, a message is displayed while the job is awaiting
scheduling. A new job cannot be submitted until the interactive job is completed or
terminated.
The
bsub command stops display of output from the shell until the job completes,
and no mail is sent to you by default. Use
Ctrl-C at any time to terminate the job.
Commands:
◆ bsub -I—Submit an interactive job
Interactive task A command that is not submitted to a batch queue and scheduled by LSF, but is
dispatched immediately. LSF locates the resources needed by the task and chooses
the best host among the candidate hosts that has the required resources and is
lightly loaded. Each command can be a single process, or it can be a group of
cooperating processes.
Tasks are run without using the batch processing features of LSF but still with the
advantage of resource requirements and selection of the best host to run the task
based on load.
Commands:
◆ lsrun—Submit an interactive task
◆ lsgrun—Submit an interactive task to a group of hosts
