What is NOPE?

Not all research projects end up with positive results. Sometimes ideas that sound enticing at first run into unexpected complexity, high overheads, or turn out simply infeasible. Such projects often end up in a proverbial researcher's drawer, and the community as a whole is not aware of dead-end or hard-to-advance research directions. NOPE is a venue that encourages publishing such results in all their "badness".

What is a "good failure"?

The best negative results help us learn from our mistakes. They can illuminate hidden obstacles or demonstrate why we need a change of course. An ideal submission to NOPE has a novel idea which sounds plausible from first principles or design intuition, but yields little to no improvement (in performance, power, area, …) in practice. The paper drills down into the reasons for the lack of improvement and proposes a plausible explanation – different technology trends, unexpected implementation complexity.

Call for Papers

Our goal is to find papers which the community can learn from and might otherwise have trouble finding a suitable venue, so we take a broad view of what constitutes a "negative" result. A good NOPE submission might entail:

Submission Guidelines

We believe in substance over style, and we encourage authors to prioritize delivering their message over conforming to a particular template. That being said, we anticipate papers will probably end up in the 4–6 page range, and we encourage authors to use a two-column format. Papers need not be anonymized.

Additionally, while one of the goals of NOPE is to find a home for papers that can sometimes be difficult to publish elsewhere, we do not wish to preclude publication elsewhere. NOPE 2015 will not be indexed with IEEE or ACM, so authors should feel free to expand and submit their work to larger venues. We discourage resubmission of previously published papers, though "second-look" papers or retrospectives fall squarely within the scope of the workshop and are welcomed.


Please submit your papers via email to: by 11:59pm (anywhere on Earth) on the deadline.
