What is DECI?

The Distributed European Computing Initiative (DECI) 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 (average award per project expected to be around 2.5 million machine hours).

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. Please note that, for the DECI-17 call, in addition to offering access to computing resources, applications-enabling and porting assistance from experts at the leading European HPC centres is offered (on request and depending on availability) to enable projects to be run on the most appropriate Tier-1 platforms in PRACE. However, these efforts are limited and will be decided upon on case by case basis.

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.

EUDAT resources and services offered in this call

Thanks to the collaboration with the pan-European Collaborative Data Infrastructure (EUDAT CDI), this call is open for projects which require the coupling of DECI Tier-1 HPC resources with data management and preservation. Around 1 PB storage capacity is available, which will correspond to about 150 TB per project awarded; bigger allocations can be discussed. EUDAT guarantees data storage at one or several of its sites across Europe for at least until June 2023 free of charge thanks to the support of the EU funded project DICE (Grant Agreement-101017207). Continuation after June 2023 can be discussed on an individual basis.
The services available can be categorised as follows:

  • Personal/project workspaces (for about 100 TB) contain different kinds of data services ranging from basic POSIX based filesystems, object-based storage to cloud storage services. Researchers and research teams use personal/project workspaces when doing active research, when data is not yet stable and is frequently changing during the data processing and analysis steps of the research data lifecycle.
  • Data archives (for about 450 TB) contain high volume cost-efficient data services in which bit preservation level durability is ensured. Services offered in this category are mostly based on systems which store data on tape, but also cost-efficient object-based storage with a replication factor of 2+ can be used. These kinds of services are often used to safely store data to bridge projects and/or computing grants.
  • Policy-based data archives (for about 300 TB) is a service category that offers services with the capability for advanced data management practices on the basis of policies, for example automated quality and integrity checks, registration of persistent identifiers, replication across geographical locations or the publication of data sets. This category is of special interest for data managers who are responsible for maintaining stable community data for the medium- and long- term duration with a high curation level.
  • Data repository (for about 150 TB) is a category of services for maintaining research data in a FAIR way, research data is well described via community defined metadata templates, persistent identifiers are registered for data sets and data objects, if data is open accessible, is closed and/or under embargo and is made available according via which licence. Data made available through services in this category are harvested and automatically made discoverable via different search engines (e.g. EUDAT B2FIND, OpenAIRE Explorer). Via services in this category communities can easily implement a FAIR digital repository in which research data can be maintained and preserved for long-term. In this category of services are also services for assigning and minting persistent identifiers and DOIs reside.
