Add one more small subsection, something like:

### How do I know if my software can run in parallel?

If you are not sure if the software you are using can efficiently use multiple cores or run across multiple nodes, you should check its documentation for instructions on how to run in parallel, or check for options that control how many threads/cores/nodes can be used.

If you can not find any information along those lines, the software you are using can probably only use a single core, and thus requesting multiple cores and/or nodes will only result in wasted sources.
