A requirement of all allocations and use of NCAR HPC resources managed by CISL, including the CMIP Analysis Platform and Research Data Archive, is to acknowledge NCAR and CISL support for your research. Our ability to identify supported scientific results helps ensure continued support from NSF and other sources for future HPC systems.

Upon completion of your project, NCAR requires an accomplishment report containing (a) the research results obtained using NCAR resources, (b) a list of scientific publications that resulted from this research, (c) the names and affiliations of graduate students who used NCAR resources, and (d) the title, author, and relevant citation data for any theses or dissertations produced using NCAR computational resources. The accomplishment report should be sent as a PDF to alloc@ucar.edu.

A PI’s or project lead’s subsequent allocations may be delayed pending compliance with these reporting requirements.

More details follow below for Derecho, Cheyenne, Yellowstone, and CMIP Analysis Platform projects, and for the use of Research Data Archive data sets.

Page contents

For Derecho projects

If you are publishing a work that uses the Derecho resource, follow the guidance for Cheyenne below, but use the appropriate calendar year, "Derecho: HPE Cray EX System" for the system name, and the Derecho DOI (https://doi.org/10.5065/qx9a-pg09).

For Cheyenne projects

Citation formats. We prefer that you cite your use of the Cheyenne system (and/or the Casper data analysis and visualization cluster) with the following citation formats, based on the source of your allocation and modified as needed to conform with citation style guidelines. Be sure to use the digital object identifier (DOI) as shown; it is unique to Cheyenne.

[1] Computational and Information Systems Laboratory. 2019. Cheyenne: HPE/SGI ICE XA System (Climate Simulation Laboratory). Boulder, CO: National Center for Atmospheric Research. doi:10.5065/D6RX99HX.

Acknowledgments. Acknowledgments are more difficult to track electronically due to the many possible variations, but you may choose to acknowledge support from Cheyenne if the citation method described above is inappropriate. You may modify the following examples as appropriate; however, please include at least the DOI in the acknowledgment text, as you would include funding agency award numbers.

For University/CHAP and NCAR allocations

We would like to acknowledge high-performance computing support from Cheyenne (doi:10.5065/D6RX99HX) provided by NCAR's Computational and Information Systems Laboratory, sponsored by the National Science Foundation.

For Climate Simulation Lab (CSL) allocations

Computing resources (doi:10.5065/D6RX99HX) were provided by the Climate Simulation Laboratory at NCAR's Computational and Information Systems Laboratory, sponsored by the National Science Foundation and other agencies.

For Wyoming-NCAR Alliance allocations

We would like to acknowledge the use of computational resources (doi:10.5065/D6RX99HX) at the NCAR-Wyoming Supercomputing Center provided by the National Science Foundation and the State of Wyoming, and supported by NCAR's Computational and Information Systems Laboratory.

For Yellowstone projects

If you are publishing a work that used the Yellowstone resource, follow the guidance for Cheyenne, but use 2016 for the citation year, "Yellowstone: IBM iDataPlex System" for the system name, and the Yellowstone ARK (http://n2t.net/ark:/85065/d7wd3xhc) for the DOI.

For CMIP Analysis Platform projects

See this CMIP Analysis Platform documentation for how to acknowledge NCAR/CISL support and for information on other requirements related to the use of CMIP data.

For use of RDA data sets

The data were provided by the Research Data Archive (RDA) of the Computational and Information Systems Laboratory at the National Center for Atmospheric Research. NCAR is supported by grants from the National Science Foundation.

We ask that you cite the dataset(s) used. Citations templates are provided on the relevant RDA dataset home pages. For an example, see the "How to Cite This Dataset" section on https://rda.ucar.edu/datasets/ds094.0/#!description.
