Call for Proposals for DECI-10 (Tier-1)

The DECI-10 call is managed by the PRACE-2IP project, which receives EC funding (RI-283493)and enhances the implementation of the HPC Research Infrastructure PRACE. PRACE-2IP is responsible for the Tier-1 access through the DECI calls.

Opening date: 5th November 2012
Closing date: 14th December 2012, 12:00 CET
Allocation start date: 1st May, 2013
Allocation period: 1 year for Project Access and DECI,
Type of access: DECI (Tier-1)

Tier-1 machines available:
IBM Blue Gene/Q, Cray XE and Cascade, and a range of large clusters including GPU resources made available from Bulgaria, Czech Republic, Finland, France, Germany, Ireland, Italy, The Netherlands, Norway, Poland, Sweden, Serbia, Spain, Switzerland, Turkey and United Kingdom.

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 2013. Resources are available on the following architectures: Cray XE, Cray Cascade, IBM Blue Gene/Q, Intel and PowerPC 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 their 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.

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 Union country or a PRACE Association member country. 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

We anticipate accepting around 40 proposals for DECI-10.
Cray XE6 – Three large Cray XE systems are available at EPCC (UK), SNIC-KTH (Sweden) and CSCS (Switzerland). The largest of these machines has a peak performance of 829 TeraFlops and a total of 90 112 cores. At CSC (Finland) a new machine with “Cascade” architecture will be available. Around 34% of the total DECI resource (equating to 48 million XE compute core hours) is available on Cray architecture.
IBM Blue Gene/Q – a BG/Q system is available at Daresbury Laboratory (UK). The Blue Gene/Q has a peak performance of 1 PetaFlops and a total of 98 304 cores and is particularly suited to projects focusing on the development of highly scalable codes. Around 37% of the total DECI resource (equating to 25 million BG/Q compute core hours) is available on this class of architecture.
Clusters – clusters are available at FZJ (Germany, Bull Nehalem cluster), RZG (Germany, IBM Sandy Bridge cluster), CINECA (Italy, Westmere cluster plus GPGPU), PSNC (Poland, SGI SMP cluster), ICM (Poland, IBM Power 7), ICHEC (Ireland, SGI ICE 8200), IPB (Serbia, AMD plus GPGPU cluster), UYBHM (Turkey, Nehalem cluster), BSC (Spain, Intel plus GPGPU cluster), and SIGMA (Norway, Megware high memory cluster, particularly suited to data intensive applications). The largest cluster has a peak performance of 207 TeraFlops and a total of 17 644 cores and the largest hybrid cluster with GPGPUs contains 548 GPUs. Around 29% of the total DECI resource (equating to 25 million cluster compute core hours) is available on this class of architecture.
The indicative amounts of CPU on offer for the call represent the lower boundaries. The total amount of CPU resource available is likely to increase due to on-going or planned procurements.

How to apply to DECI-10

All DECI proposals should be submitted by email to using the standard DECI proposal template.
The template for proposals is available here and it must be carefully respected. The completed form should be sent to Proposals that do not follow the template or which are incomplete cannot be considered for peer review. 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 14th December, 2012, at 12:00 CET.

Process details and deadlines for Tier-1 DECI proposals

The call will close at 12:00 CET on the 14th December 2012. 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 21st December at 12:00 CET. Anything received after 21st December at 12:00 CET will NOT be accepted nor considered in the review process. Between 14th December – 21st December 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 12:00 CET on 21st December, all applicants will receive confirmation that their proposals have been correctly submitted and that they meet the eligibility criteria. From 21st December 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 2013.


Core hour: Elapsed time (wall clock time) in which a core is allocated to the user;
GPU hour: Elapsed time in which a graphical processing unit (GPU) is allocated to the user.
