  • Discussion and adaptation of proposals. (during Oct 20 F2F Mtg).
  • Possible adaptations:
    • Dismiss proposals that are not compliant with WP9 goals.
    • Combine proposals to investigate several aspects of a particular prototype (e.g. energy efficiency and programmability of certain hardware).
    • Combine proposals of similar nature.
    • Add small contributions from other partners to good proposals.
    • Adjust amount of funding necessary for each prototype proposals.
    • Try to narrow the field down to 3-5 prototypes.
prototype selection process slide 3 4
Prototype SelectionProcess (slide 3/4)
  • Fine-grained proposals for the agreed prototypes.Proposals are typically handed in by a consortium of partners. Proposals do not exceed 10 pages. They contain:
    • High-level overview of the prototype.
    • Detailed description of the prototype and the associated assessment.
    • Impact of the prototype on Exascale computing, software, energy efficiency, scientific communities/codes/applications and/or hardware development.
    • Detailed timeline for the assessment.
    • Break-down of tasks between partners.
    • Costs & requested funding (including the distribution between partners).
