2 Realizing the ESFRI Vision for an HPC RI European HPC- facilities at the top of an HPC provisioning pyramid Tier- 0: European Centres for Petaflop/s Tier- 1: National Centres Tier- 2: Regional/University Centres Creation of a European HPC ecosystem HPC service providers on all tiers Scientific and industrial user communities The European HPC hard- and software industry Other e- Infrastructures # of systems capability

3 PRACE History HPC part of the ESFRI R oadmap; creation of a vision involving 15 European countries Signature of the MoU Creation of the Scientific Case HPCEUR HET 2006 Creation of the PRACE Research Infrastructure PRACE Initiative PRACE PP PRACE RI PRACE 1IP 2013 PRACE 3IP PRACE 2IP PRACE PRACE 4IP

4 PRACE is the European High- End HPC Infrastructure provides access to 6 Tier- 0 systems, funded by 4 countries: DE, ES, FR, IT is preparing a Tier- 1 offer, replacing the current DECI has provided 5.5 Billion Core- hours to hundreds of user projects since 2010 is providing extensive training though 6 PRACE Advanced Training Centres (PATC), seasonal schools, summer student programme, workshops, currently has 25 members, representing 25 countries has secured national contributions of 450 M and 67 M EC funding is developing its strategy for PRACE is user- demand driven Scientific Steering Committee advises on all scientific matters, in particular the access to PRACE resources through Peer Review User Forum provides feedback and technical requirements from end- users Scientific Case : requirements and recommendations >100 leading European Scientists contributed to this update ri.eu/prace- The- Scientific- Case- for- HPC

5 PRACE is building the top of the pyramid... Sixth p roduction s ystem available b y January 2 013: 1 Petaflop/s IBM (MareNostrum) at BSC. First p roduction s ystem available: 1 Petaflop/s IBM BlueGene/P (JUGENE) at G CS ( Gauss Centre for Supercomputing) p artner FZJ Upgrade: 5.9 Petaflop/s (Forschungszentrum Jülich) IBM Blue G ene/q (JUQUEEN) Fifth p roduction s ystem available b y August 2 011: 2.1 Petaflop/s IIBM BG/Q (FERMI) at CINEC. Second p roduction s ystem available: Bull Bullx CURIE at G ENCI p artner CEA. Full capacity of 1.7 Petaflop/s reached by late Fourth p roduction s ystem available b y mid 2 012: 3.2 Petaflop/s IBM ( SuperMUC) at G CS p artner LRZ (Leibniz- Rechenzentrum). Third p roduction s ystem available b y the end of 2 011: 3,8 Petaflop/s Cray (HORNET) at G CS p artner H LRS ( High Performance Computing Center Stuttgart).

7 Future of PRACE PRACE 2.0 strategy for Provisioning of Tier- 0 services Tier- 1 services for Tier- 0 systems Tier- 1 optional programme (DECI) Training and support activities Funding mainly from national sources Horizon 2020 support PRACE- 3IP ended (except PCP) in mid 2014 PRACE- 4IP - EINFRA started spring 2015 Kick- off meeting in Ostrava!

8 Role of IT4Innovations in PRACE National node of PRACE in Czech Republic Provider of Tier- 1 system for PRACE Plan to contribute with 10% of computational resources of IT4I Support for accessing PRACE resources and training activities Organizing of training and dissemination activities Seasonal and regular courses Providing information about PRACE via Workshops Newsletters Website

9 Accessing the PRACE RI Access Model Proposals are evaluated in a single European peer review process governed by the PRACE Scientific Steering Committee. Two types of resource allocations for Tier- 0 Project access large- scale, computationally intensive projects Preparatory access - Test / evaluation access, code scaling and optimization DECI (Distributed European Computing Initiative) Access to national Tier- 1 systems Support by experts from Tier- 1 centres

10 Preparatory access PRACE Preparatory access is managed through rolling call, opened all year round. There are no closing dates but technical evaluations are organized every 3 months at defined cut- off dates Types of preparatory access Type A: Code scalability tests (max 2 months) Applicants may use this preparatory access to obtain scalability plots of the performance of the code on a certain HPC system; this allows the applicant to obtain use of up- to- date information when applying to PRACE Project access type of calls. Type B. Code development and optimisation (max 6 months) Applicants may use preparatory access to undertake adaptations to the application code. Applicants will need to describe the proposed development plan in detail, including the human resources (and expertise) available to implement the project. Type C. Code development and optimisation with the support of PRACE experts (max 6 months) Applicants use this type of access for the same purposes as type B. In addition, under preparatory access type C, the applicants may require the support of PRACE experts to improve the application code. Administrative Validation: 2 working days after the cut- off date Allocation Decision: approx. 30 calendar days after the cut- off date Access Start Date: Access is provided starting approx. 45 calendar days after the cut- off date. Next cut- off date 1 st December 2015 (23rd cut- off) HLRS Hornet (XC40)

11 Project access PRACE will publish its twice- yearly Calls for Proposals according to a fixed rhythm: Call opens in February - > Access is provided starting September of the same year. Call opens in September - > Access is provided starting March of the next year. The PRACE peer review consists of two phases of assessment: technical and scientific. Technical assessment The need to use a PRACE resource Software availability on the requested resource Feasibility of the requested resource Scientific assessment Scientific excellence Novelty and transformative qualities Relevance to the call Methodology Dissemination Management Currently no call open till PRACE2.0!

12 DECI (Tier-1) access DECI (Distributed European Computing Initiative) is an European single- project HPC access scheme for Tier- 1 systems and services. Juste- retour mechanism for exchange of Tier- 1 resources Last call: Call for Proposals for DECI- 12 (Tier- 1) Opening date: 2 nd December 2013 Closing date: 13 th January 2014 Allocation start date: 1 st May, 2014 Allocation period: 1 year DECI12 details: Total allocation: DECI std. core hour ( ANSELM core hours) CZ contribution: DECI std. core hours (approx core hours Anselm) Submitted projects: 58 (0 from CZ) Granted projects: 37 (0 from CZ) Call for DECI- 13 (PRACE Tier- 1 Optional programme) is opened!
