Releasing tasks is much easier than acquiring task in my recollection. There are also limitations. So, read carefully. A lot of big HPC shops use this. For long tailed job runs where the initial run is in parallel using say the entirety of the node (or several nodes), and the end may take 5-10 minutes stitching together results or generating images and doing cleanup that is single threaded. This way, the next parallel job can startup while the last job is still performing that long tailed operation. It does improve throughput at the expense of a little jitter at the job start.

Subject: How to add LSF tasks to a running job?
Hi! I know that there is a -n option in the bsub command to specify the number of tasks in a job.
I wonder if there is a way to add or remove tasks once the submitted job is started? Thanks.
