**What's the disadvantage of submitting jobs with long walltimes if they are not needed?**-
Answer

The batch system will take longer to schedule your jobs. In general, ask for as few resources as possible. **What's the problem if a single swarm subjob takes 1 hr, and you want to submit the swarm with a bundle factor of 500?**-
Answer

500 * 1 hr = 500 hours = 20 days. This is longer than the max walltime of 10 days, and your swarm command will give an error.You will need to reduce the bundle factor to a max of 240 (exactly 10 days) or a bit less.
