Common problem with programmers: when they learn a term means something, they associate that term absolutely with that meaning (common in other fields with people who are highly analytical, IME).

The HPC people are referring to a "job queue", rather than a "ADT queue". Those are distinct things, the ADT queue is a much more restrictive defintion, but it's not an exclusive one. HPC queues are more like priority queues with complex ranking functions (and queues of queues), just like real-life queues where people can cut by paying more money (first class airline ticket).
