Interactive Jobs with bsub
Submitting Interactive Jobs
Use the bsub -I option to submit batch interactive jobs, and the bsub -Is
and -Ip options to submit batch interactive jobs in pseudo-terminals.
Pseudo-terminals are not supported for Windows.
For more details, see the bsub(1) man page.
Finding out which queues accept interactive jobs
Before you submit an interactive job, you need to find out which queues
accept interactive jobs with the bqueues -l command.
If the output of this command contains the following, this is a batch-only
queue. This queue does not accept interactive jobs:
SCHEDULING POLICIES: NO_INTERACTIVE
If the output contains the following, this is an interactive-only queue:
SCHEDULING POLICIES: ONLY_INTERACTIVE
If none of the above are defined or if SCHEDULING POLICIES is not in the
output of bqueues -l, both interactive and batch jobs are accepted by the
queue.
You configure interactive queues in the lsb.queues file.
Submitting an interactive job
Use the bsub -I option to submit an interactive batch job.
A new job cannot be submitted until the interactive job is completed or
terminated.
When an interactive job is submitted, a message is displayed while the job is
awaiting scheduling. The bsub command stops display of output from the shell
until the job completes, and no mail is sent to the user by default. A user can
issue a ctrl-c at any time to terminate the job.
Interactive jobs cannot be checkpointed.
Interactive batch jobs cannot be rerunnable (bsub -r) or submitted to
rerunnable queues (RERUNNABLE=y in lsb.queues).
Examples ◆ % bsub -I ls
Submits a batch interactive job which displays the output of ls at the user’s
terminal.
◆ % bsub -I -q interactive -n 4,10 lsmake
This example starts Platform Make on 4 to 10 processors and displays the
output on the terminal.
