Define maximum jobs in queue inside lsb.queues

Question

I am trying to find out how many jobs a queue that I defined can hold.

Which parameter holds the maximum number of jobs that can be submitted to a specific queue?

Answer 1

When you say max jobs in a queue, I assume that you mean pending, suspended and running, but not done or exit. Here are the closest options that I can think of.

1. Use an esub to enforce the limit. While this can get you what you want, its a little hairy. You can use the NJOBS field of bqueues to get the current number of jobs in the queue. This option has a small race condition as some time passes between the check and submission.

2. There's a global limit for pending jobs. lsb.params, MAX_PEND_JOBS

3. The lsb.queues parameter QJOB_LIMIT can limit the max job slot for running jobs. But it limits job dispatch, not job submission.

4. Similar to 3 except you can limit jobs rather than job slots. Do this with a limit in lsb.resources.
