Rules of the road

Background

Vlasiator is a significant investment, and its development has taken many years (since 2008). Vlasiator is funded by the European Research Council and the Academy of Finland.

Vlasiator requires considerable amount of human resources. The code is being developed by external funding. Runs are carried out with supercomputer resources that the PI team applies for from competitive sources (such as PRACE and CSC Grand Challenge). Each run needs to be babysat.

While Vlasiator is licensed under GPL-2, these rules of the road have a similar philosophy as are generally in use for instruments. Vlasiator is the only one of its kind in the world, having no similar benchmark. Hence we need to make sure that all Vlasiator results have been verified by by the PI-team.

The user is strongly advised to utilise Vlasiator as described below.

PI and the PI-team

The PI-team makes all decisions pertaining to the Vlasiator master version. All data requests and other support questions should be addressed to the PI. The PI-team decides about the time and place in which the peer-reviewed data becomes public.

Vlasiator enthusiasts

The PI-team welcomes collaborations! Do reach out to us and make a data request, which we handle on the best effort basis. Any publications or presentations need to follow the publication rules below, and the further distribution of the accessed data is not allowed without the consent of the PI-team. The movies made public through the Vlasiator web pages can be freely used in scientific work, presentations and publications, bearing in mind the publications rules of the road below.

Publications and presentations

All publications showing Vlasiator data shall cite these two Vlasiator architectural papers

All publications or presentations showing Vlasiator data need to be inspected by someone from the Vlasiator PI-team. The PI and the relevant PI-team members shall be added as co-authors in the publication. The Vlasiator PI-team may publish the Vlasiator data shown in the publication through the Vlasiator web page.

Acknowledgement for publications and presentations

Vlasiator is developed by the European Research Council Starting grant 200141-QuESpace, and Consolidator grant GA682068-PRESTISSIMO received by the Vlasiator PI. Vlasiator has also received funding from the Academy of Finland. See www.helsinki.fi/vlasiator

Presentations

All presentations showing Vlasiator data shall include a Vlasiator slide given by the PI-team. The presentation shall also include the Vlasiator logo. The slide and acknowledgement are available from the PI time upon request.
