  2. Outline • GRNET dual mission: • Research Networking and Grid infrastructure • The HellasGrid National Grid initiative • Infrastructure • Organisation • Applications communities • HellasGrid as part of the European efforts • Networking and Grid projects • Challenges/Experiences Athens, 19 April 2006

  3. GRNET Dual Mission • The EU e-Infrastructure vision: Integrated Networking + Grid infrastructures • GRNET was one of the first NRENs* in Europe adopting the EU e-Infrastructure initiative: • Providing both networking and grid infrastructures * NREN: National Research and Education Network • Being infrastructure-oriented and application-neutral serving all user eScience communities • Expanding its scope to e-Business and e-Government Source: European Commission Unit F3: Research Infrastructures Athens, 19 April 2006

  4. GRNET strategic projects and funding • Grid projects • Hellasgrid Task Force, 2002-2004, (support money) • Hellasgrid Strategy Document • Pilot Grid node @ Demokritos (0,5M by GRNET2) • Hellasgrid Project, 2004-2007, ~2 MEuro • ~800 CPUs, ~ 90TB storage (30TB disks + 60 TB tape libraries), 4 advanced video-conferencing Access Grid nodes • Grid Applications Call, 2006-2007,~0,5M • PanEuropean integration projects: EGEEProject, 2004-2006, 1,3MEuros EGEE-II, 2006-2008, 1,8M Euros • Supported operations, training, policies • Regional Support projects: SEEGRID, SEEGRID2, Eumedgrid, EuChinaGrid • Other projects:GridCC, e-IRGSP • Research Network projects • GRNET2 project, 2000-2005, 20 MEuro • 2,5 Gbps leased lambda backbone network • Pilot dark fiber acquisition projects (15 years lease) + optical equipment • Pilot Grid node @ Demokritos (Isabella) • Access project (called “105”), 2005-2008, 10 MEuro • 1 Gigabit Access for ~50 institutes • GRNET3 project, 2005-2008, 30 MEuro (recently approved!) • Dark fiber research back-bone network in Greece • Optical MANs for Athens, Thessaloniki (the rest to be covered by regional MANs (called “93”) • Optical equipment RFI already published • PanEuropean connectivity & integration project: GEANT2, 2004-2008 • Regional Support Projects: SEEREN-SEEREN2, Eumedconnect Athens, 19 April 2006

  5. The GRNET Network • Backbone is currently based on 2,5 Gbps leased lambdas • Dark fiber has been acquired for 3 network spans (pilot phase) • Dark fiber tender for the whole backbone on-going (one offer received) • International connectivity 2 * 10 Gbps any day (currently 2* 2,5 Gbps) Athens, 19 April 2006

  6. The HellasGrid National Grid Initiative • HellasGrid Task Force appointed by the Ministry of Economy and Finance at the end of 2002 (MNEC is running the national InfoSoc programme) • A strategy group supported by a scientific committee • Produced a strategy document • The Task Force prepared the National Integration Proposal • The HellasGrid MoU was signed at the end of 2003 • Pilot Phase (Phase I): 2003-2004 • GRNET Pilot Infrastructure installation • Isabella site: 64 CPUs, 10 TB SAN, 12 TB Tape Library • Participation in EGEE proposal, Coordination of SEE-GRID • Consolidation Phase (Phase II): 2004-2006 • HellasGrid project implementation • Extension of Grid infrastructure (~800 CPUs, 30TB disks, 60TB tape libraries) – (~2 MEuros) • Integration in EGEE • The HellasGrid MoU was used to form a Joint Research Unit (JRU) • GRNET provided a recognition letter by the Ministry after EC request • Further application support (~0,5M – 1M Euros) • Investigation for further infrastructure support (~1 MEuros) Athens, 19 April 2006

  8. HELLASGRID infrastructure http://www.hellasgrid.gr/infrastructure • HG-01 cluster @ Demokritos: 64 CPU, 10TB FC SAN, 12TB Tape Library, EGEE LCG2 middleware • HG02-HG06 clusters located in: • Athens (NDC/EKT, IASA) • Thessaloniki (AUTH) • Crete (ICS-FORTH) • Patras (CTI) • ~800 CPUs (x86_64, 2 GB RAM, 80GB HDD, 2x Gbit) • ~30 TBytes total raw SAN storage capacity • ~80TBytes Tape Library • 4 Access Grid nodes Athens, 19 April 2006

  9. HG organisation: Teamwork! • Overall coordination: GRNET headquarters • Cooperation with HellaGrid partners: • Main site + ROC operator : HG-01-GRNET (Isabella, cslab@ICCS/NTUA) • HG-02…HG-06 sites + operation centers (NDC, IASA, AUTH, FORTH, CTI) • 5 smaller private sites (AUTH, UoM, FORTH, Demokritos, HEP-NTUA) • HG CA and VOMS (GridAUTH, Dept. of Physics, AUTH) • HG helpdesk (CTI) • Regional monitoring tools(ICS-FORTH) • HG user support/apps (Demokritos + all site teams) • 4 AccessGRID sites HG membership: ~18 members (10 Universities + 8 Research Institutes) 6 HellasGrid+5 private sites > 900 CPUs in total Athens, 19 April 2006

  17. SEE Europe promoting the NGI/EGI model • NGI: National Grid Initiative • Infrastructure oriented & application neutral • Not driven by applications • GRNET acts as an early champion for the SEE area • One partner per country since EGEE Phase I! • EGEE-SEE and SEE-GRID countries adopted the same model! Athens, 19 April 2006

  18. Challenges/Experiences/Conclusions • Building the HG infrastructure proved difficult • Housing, SLAs with local institutes are slow, tedious and expensive! • Getting applications /users to exploit the infrastructure is slow! • Training/education and dissemination is important • Applicationprojects and funding are essential! • Received 45 proposals in last Grid-Applications call! • Sustainability of the infrastructure and services • Equipment will need to be changed after 3-5 years • Local “incubators” for GRID technology needed: • Experts in local sites • Operators should have appropriate mentality (shifts, support) • Gained a lot from networking experience (NOCs, NOC-ROC cooperation) • Regional, Pan-European and International collaborations are vital • Our European friends lead the way: Middleware, VOs, support projects Athens, 19 April 2006
