Resources are available on the following architectures: Cray XC30/Cray XC40, Intel clusters with various processor and memory configurations, and hybrid systems including clusters with GPGPU accelerators or Xeon Phi Co-processors (KNC), made available from the Czech Republic, Finland, Greece, Hungary, Ireland, Norway, Poland, Spain, Sweden, the Netherlands, and the UK. Applicants need not specify a particular machine or architecture, but if they do, PRACE will endeavour to take these preferences into account.
The Distributed European Computing Initiative is designed for projects requiring access to Tier-1 resources not currently available in the PI's own country or for international collaborations. These 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. The remaining time (up to 30%) is reserved for projects from countries which are not providing resources to the call. Individual projects are limited to around 5 million machine hours, the average award per project expected to be around 2.5 million machine hours.
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. Some support is available for setting up, porting and running codes efficiently on the resources assigned.
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.
Applicants should apply to DECI via the submission tool. The DECI support team is available to answer questions by e-mail while the call is open and applicants are encouraged to contact the team 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.
