That is a weird request, a source doesn’t need to be published in a journal to be cite-able. On the other hand, if you put a bibtex snippet on your site that indicates how you’d like to be cited, that is super helpful.
I wasn't very clear in my comment. I think the idea was that if the thing they were citing was a journal article, then the citations would actually mean something, as widely-cited journal articles are one of the currencies of most academic fields. While one certainly can cite an unpublished document, the author doesn't necessarily gain much from it in terms of their academic CV.
If someone writes a piece of software specifically for the purposes of doing certain types of scientific research, and then other scientists use this software to help conduct published experiments, then IMO it really ought to be possible to give that person meaningful credit for their work. It's a perfectly legitimate way to contribute to a field, even if it does not take the form of a paper. But with the system as it stands, the only way to get meaningful credit is to publish a pointless paper saying, in effect, "Hey! I wrote some software!"

I should probably have done that, but from my point of view it didn't really matter. I have a name, and the software had a website. I didn't really mind exactly how individual people chose to cite it. The absence of a ready-baked bibtex snippet would never be accepted as an excuse for failing to cite any other kind of source.
Ole did provide a BibTeX entry to a USENIX magazine article about Parallel, which is fine, though I was always taught that non-journal references generally belong in footnotes or an appendix and not the bibliography, especially for something you’re not referencing for research purposes. Not sure if footnote or appendix or open-source usage citations count for what Ole needs; I’d guess he wants citations you can easily index using Google Scholar or other citation indexes, i.e. it should count toward Parallel’s H-index (https://en.wikipedia.org/wiki/H-index)
