DUNE Software Framework Requirements - HSF Review

In the spring of 2021, the DUNE experiment contacted the HEP Software Foundation (HSF) to review a set of requirements drawn up to help the experiment determine how to meet its framework needs. In response, the HSF coordinators and framework working-group conveners assembled a panel of framework experts from across the international HEP community.  A public workshop was held on 2-3 June 2021 between members of the DUNE experiment and the HSF panelists, conveners, and coordinators. The DUNE framework requirements document was discussed in detail, along with questions that arose prior to the workshop.  This document presents the findings of the HSF review panel, including the coordinators and framework working-group conveners, who served as ex officio members of the review process.
