What is DECI?

The Distributed European Computing Initiative (DECI) is designed for projects requiring access to resources not currently available in the PI's own country but where those projects do not require resources on the very largest (Tier-0) European Supercomputers or very large allocations of CPU. DECI is a resource exchange programme where resources are provided by a subset of PRACE members and awarded via the juste retour principle. This means that projects from each contributing country will in total receive at least 70 % of the amount of resources contributed to DECI by the PI's own country but will be allocated to a machine with an architecture and set up which best matches the needs of that project. (On occasions projects may be placed on a machine within the PI's own country.) The remaining time (up to 30%) is reserved for projects from countries which are not providing resources to the call.

Scope of the Tier-1 call and criteria for access

DECI enables European researchers to obtain access to the most powerful national (Tier-1) computing resources in Europe regardless of their country of origin or employment and to enhance the impact of European science and technology at the highest level. Proposals must deal with complex, demanding, innovative simulations that would not be possible without Tier-1 access. Limited support for helping to get codes up and running will be provided on a best effort basis from parties involved in DECI.

Eligibility for Tier-1

Proposals from academia and industry are eligible, as long as the project leader is undertaking non-proprietary research in a European country (European Union, candidates, associated countries and PRACE member countries). Project leaders will typically be employed in research organisations (academic or industrial). Individual HPC centres may have further restrictions on who is eligible to use the machines, e.g. due to US export rules. Further information is available on request.

How to apply to DECI calls

Applicants should apply to DECI via our submission tool here https://deci-peer-review.cines.fr/. The DECI support team is available to answer questions by email while the call is open and applicants are encouraged to contact us if they have any questions. Late applications cannot be accepted. In the case of technical difficulties, the decision of the DECI Peer Review Team as to whether an application can be accepted is final. Applicants are advised to submit as early as possible before the deadline.
