Comparing Norc to batch is similar to comparing it to cron. Many of the limitations of batch processing come with retrying or auditing complex trees of dependencies (bigger than a handful of tasks).

It's like wrapper scripts. They work well until they don't: managing the logs, getting efficient execution, understanding what happens when all become quite unwieldy, whereas a Norc-like approach proves more self-documenting and easy to manage.

I believe resource management is limited to overall system load. Batch isn't designed for things like managing available licenses.

I'm not a huge expert at batch, so if I've missed something let me know.
