Call for Proposals for DECI-12 (Tier-1)

The DECI-12 call is supported and managed by the PRACE-3IP project in addition to the Parties participating in the “Non-binding memorandum of understanding (MoU) on interim Tier-1 exchange programme”. PRACE-3IP receives EC funding (RI-312763) and enhances the implementation of the HPC Research Infrastructure PRACE. PRACE-3IP is responsible for the Tier-1 access through the DECI calls until its end. After the end of the PRACE-3IP project, Tier-1 access and reduced support for users is offered in kind by the Parties of the Tier-1 exchange programme MoU.

Opening date: 18th December 2013, 12:00 CET
Closing date: 20th January 2014, 17:00 CET
Allocation start date: 1st May, 2014
Allocation period: 1 year for Project Access
Type of access: DECI (Tier-1)

Tier-1 machines available: Cray XE/XC, and a range of large clusters including GPU resources made available from Cyprus, Finland, Hungary, Ireland, Italy, Poland, Serbia, Sweden, Switzerland, the Czech Republic, the Netherlands, the United Kingdom and Turkey.

DECI provides single project cross-national access to European Tier-1 resources (national systems). Access will be awarded for a period of 12 months, beginning 1st May 2014. Resources are available on the following architectures: Cray XE6, Cray XC30, IBM Blue Gene/Q, Intel clusters (various processor and memory configurations) and hybrid systems (clusters with GPGPU accelerators). Applicants need not specify a particular machine or architecture, but if they do, we will endeavour to take these preferences into account.

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, 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. Note that after the end of the PRACE-3IP project limited support will be provided on a best effort basis from parties of the Tier-1 resource exchange MoU.

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.

Tier-1 Computing Resources offered in this call

Cray Large Cray XE6 systems are available at SNIC-KTH (Sweden) and CSCS (Switzerland). The largest of these machines has a peak performance of 400 TeraFlops and a total of 47,872 cores. At CSC (Finland) a 11,776-core (Sandy Bridge) machine and at EPCC (UK) a 72,192-core (Ivy Bridge) machine, both with XC30 architectures are available. Around 50% of the total DECI resource (equating to 38 million XE6 or XC30 compute core hours) is available on Cray architecture. IBM Blue Gene/Q access is available at the STFC Hartree Centre and this system has a Linpack performance of just over one Pflop/s with 98,304 cores. Around 10% of the total DECI resource (equating to 25 million Blue Gene/Q compute core hours) is available on this architecture. Clusters – clusters are available CaSToRC (Cyprus, Westmere cluster plus GPGPU), CINECA (Italy, Westmere cluster plus GPGPU), CYFRONET (Intel Xeon), ICHEC (Ireland, x86 Cluster with shared memory and accelerator partitions), ICM (Poland, IBM Power 7), IPB (Serbia, Intel Sandy Bridge plus GPGPU cluster), NIIFI (Hungary, HP Magny-Cours Cluster), PSNC (Poland, SGI SMP cluster), SURFsara (the Netherlands, Bullx Ivy Bridge Cluster), UHEM (Turkey, Nehalem cluster), VSB-TUO (Bull Intel Xeon) and WCSS (Poland, Intel Xeon). Around 40% of the total DECI resource (equating to 25 million cluster compute core hours) is available on this class of architecture.

How to apply to DECI-12

Applicants should apply to DECI via our submission tool here. 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. The deadline for submission of proposals for Tier-1 systems is 20th January, 2014, at 17:00 CET.

Process details and deadlines for Tier-1 DECI proposals

The call will close at 17:00 CET on the 20th January 2014. The DECI Peer Review Team will perform an administrative validation check. In case of administrative inaccuracies the applicant will receive an email asking for administrative details. The deadline for the applicant to provide such details is 27th January 2014 at 17:00 CET. Anything received after 27th January 2014 at 17:00 CET will NOT be accepted nor considered in the review process. Between 20th January 2014 and 27th January 2014 the DECI Peer Review Team will accept modified proposals ONLY when these supply further details in reply to requests from PRACE. Several submissions of the same proposal before the submission deadline are permitted, but only the last one will be considered. By 17:00 CET on 27th January 2014, all applicants will receive confirmation that their proposals have been correctly submitted and that they meet the eligibility criteria. From 27th January the projects will be technically and scientifically peer reviewed. The DECI proposals will be peer-reviewed by national peer-review panels. The applicants will be informed of the review results in early April 2014.


Core hour: Elapsed time (wall clock time) in which a core is allocated to the user.
