Inno4scale is organising webinars to provide potential proposers with an introduction to the key details relating to submission of a proposal. The webinar will start with a presentation about the call objectives, expectations, budget/eligibility conditions and details about the submission and evaluation process. This will be followed by a Q&A session providing the possibility to discuss directly with the call management team about general issues and processes concerning proposal submission. While questions about technical content of a proposal are not in scope, the webinar does provide an opportunity for proposers from research domains new to the field of extreme scale computing to ask for support in connecting to HPC expert groups that could collaborate on a proposal submission.
