The Inno4scale project will support the EuroHPC Joint Undertaking in achieving the efficient use of its supercomputing resources through the development of novel algorithms for applications on those resources. It will do this by funding a set of focused innovation studies that will realise proof-of-concept demonstrators of fundamentally new and innovative algorithms with a clearly identified potential impact through integration and use in important applications.

This call for proposals targets highest quality research and development studies leading to proof-of-concept demonstrators exhibiting enhanced performance relevant for important applications executed on exascale systems. The call addresses researchers that have identified novel concepts for computational solutions of important numerical problems in scientific applications and use cases which rely on exascale supercomputers. The central goal is the conversion of mathematical concepts for algorithms, for example by a fundamentally new decomposition of a numerical problem for the efficient use of hierarchical memory to exploit heterogeneous and massively parallel computing capabilities of upcoming exascale supercomputer architectures, into proof-of-concept implementations to explore and assess potential performance gains for common HPC applications.

Proposals and proposed new algorithms will be assessed on the basis of their potential to reduce resource consumption of typical use cases executed on the European supercomputer infrastructure across applications and application domains, which must be clearly demonstrated by applicants.Innovation study activities for the successful proposals are expected to commence at TRL 0-1 and achieve TRL 3-4 by the end of the 12-month study period.

Key Call Details

Submission Deadline: 28th September 2023, at 17:00 Brussels local time

Expected duration of innovation studies: maximum 12 months with expected commencement not later than 1st February 2024

Funding for the Call: The indicative total funding budget is € 4 M.

The maximum funding request per proposal is € 200,000 (covering all participants).

The maximum level of effort to be supported for a proposed innovation study is 24 person months (in total).

Proposals to Inno4scale Call-2023 that do not adhere to the abovementioned funding restrictions will be rejected without further evaluation.


The proposed innovation studies are expected to:

  1. Demonstrate scientific excellence on the identified and proposed novel, forward-looking and potentially disruptive approaches to the solution of complex mathematical, numerical or data processing problems on current and future European exascale supercomputers.
  2. Present proofs-of-concepts and solutions, which:
    • Clearly demonstrate great potential to solve currently non-tractable computational challenges in the context of use of the European flagship HPC systems;
    • Clearly demonstrate significantly superior performance compared to existing solutions and exploiting the specific capabilities of Exascale supercomputers by recovering compute or improving substantially time-to-solution and energy-to-solution for important use cases, possibly across scientific domains;
    • Demonstrate the potential to be integrated into important applications, addressing relevant use cases with a broad user base.
  3. Involve a balanced and appropriate consortium which:
    • Includes all necessary parties required for the effective and efficient execution of the proposed study;
    • Involves at most 3 organisations, each of which is assigned at least 6 person months of effort.
  4. Define the HPC computing resources they need and budget for them. Successful proposals will be encouraged and assisted to obtain access to exascale technology for their development purposes, notably through the Benchmark and Development Access calls for the EuroHPC JU systems, in order to test and implement their algorithm concepts and/or novel solutions. (Inno4scale will not be in a position to provide computing resources).
  5. Deliver, as part of their final reporting, a report suitable for broad communication to non-technical experts (incl. stakeholders and the general public).
