2. GRNET mission • GRNET is a state-owned company operating under the supervision of the Ministry of Education (General Secretariat of Research & Technology); non-profit • Main mission is to provide high-quality electronic infrastructure services to the Greek academic and research institutions: • National and international connectivity services • Distributed Computing Infrastructure services (computing, storage, visualisation) • Supporting activity is the promotion and dissemination of the use of ICT in the public and private sector towards an e-Government, e-Learning and e-Business environment • Main sources of funding are the Operational Programme for the Information Society, Ministry of Economy and Finance and EC projects • GRNET has been certified by ISO 9001:2000 in project management

3. Pan-EU e-Infrastructures vision e-Science Collaborations • The Research Network infrastructure provides fast interconnection and advanced services among Research and Education institutes of different countries’ • The Research Distributed Computing Infrastructure provides a distributed environment for sharing computing power, storage, instruments and databases through the appropriate software (middleware) in order to solve complex application problems • This integrated networking & DCI environment is called electronic infrastructure (eInfrastructure) allowing new methods of global collaborative research - often referred to as electronic science (eScience) • GRNET was one of the first NRENs in Europe to expand its services to grid and computing in general; infrastructure-oriented and application-neutral Distributed Computing Infrastructure Network Infrastructure

4. GRNET main networking tasks • Interconnects universities, research centers, academic organizations (>150), primary and secondary schools (15000) • 500.000 end-users • Continuously upgrades the national backbone (Dark fiber backbone (Nx10 Gbps), institutions access (1 || 10 Gbps per institution) and international backbone (currently at 4*10 Gbps) • Operatesthe GR Internet Exchange (GR-IX), peering of Greek commercial Internet Service Providers at 10Gbps each • Cooperates with Greek and international research and academic institutions for the development of innovative networking services

5. GRNET network evolution:from GRNET2 to GRNET3 GRNET3: dark fibre based, 10Gbps capable, 30M€, 2005-2008 GRNET2: 2,5Gbps leased lambdas, 20M€, 2000-2005

7. GRNET network evolution:from GRNET3 to GRNET4 GRNET3: dark fibres, 10Gbps capable, 30M€, 2005-08 GRNET4: Equipment upgrades, 8M€, 2012-2015 • Service Oriented Design • Optical Services Layer: physical layer connectivity • Carrier Services Layer: Carrier Ethernet (MPLS) interconnection • IP Services Layer: IP interconnection among GRNET customers and the rest of Internet • 40/100Gbps wavelengths based on PM-QPSK modulation

8. HELLASGRID (HG) infrastructure http://www.hellasgrid.gr/infrastructure • HG-01cluster (pilot phase): • @Demokritos - Athens • 64 CPU, 10TB FC SAN, 12TB Tape Library, gLite middleware • HG02-HG07 clusters (HG project): • Athens (NDC/EKT,Min EDU, IASA), Thessaloniki (AUTH), Crete (ICS-FORTH).Patras (CTI) • ~1200 Cores • ~40 TBytes total raw SAN storage capacity • ~80TBytes Tape Library • 6 extra Sites offered by Greek Universities/Research institutes (FORTH-ICS, AUTH,IASA, UoA, UoI, UOI-HEPLAB, Upatras) • ~600 Cores and 200 TB of Storage • Total funding ~2Me 8

9. HELLASGRID applications • HECTOR: Enabling Microarray Experiments over the Hellenic Grid Infrastructure • GRISSOM Platform: Grids for In Silico Systems Biology and Medicine • Evaluating the impact of climate change on European air quality • Density Functional Theory Calculations on Atmospheric Degradation Reactions of Fluorinated Propenes • Investigating the nature of explosive percolation transition • First-principles studies on traditional and emerging materials 9

10. High Performance Computing • Goal is the development of a national HPC infrastructure that will join PRACE Tier-1 European infrastructure • Budget 3.5MEuro • Procurement and installation of HPC infrastructure • Operation and provision of support services • Aiming for at least a ~150 Tflops system • Hosted in GRNET’s existing Datacenter • Support for a wide range of scientific disciplines: • Biomedicince, Bioinformatics, Computational Engineering, Physics, Meteorology, Climatology, Seismology, Computational Chemistry etc. • Based on the results of the HellasHPC feasibility study • National survey among 29 academic and research institutes (2010) • Collected requirements from 200 scientific applications developed by 162 research teams from various scientific domains

11. Cloud for R&E: the process • Vision: flexible, production-quality cloud services for Greek R&E community • Rationale: • Step beyond Grid in terms of flexibility and availability • Economies of scale for the community; solving understaffing problems, poor service, low maintenance • Minimizes the investment in equipment and support contracts • Know-how from NOC “Service boxes” (Vima service); as well as Grid • Policy background: existing MoU in place for Grid computing, expanding for HPC as well • Strategy: • Technical workshops and requirements capture meetings • Gradual offering of services, starting with storage, moving to VM on demand, IaaS, and then SaaS • Paving the way to public sector • Funding: in the context of GRNET4 project, 2.2ME DCs; 4.5ME s/w and services)

12. Cloud for R&E: Why? • STUDENT- It gives me the opportunity to test different kinds of software on a machine that I no longer need after my work is done • PROFESSOR - It makes it possible for me to deploy PC labs without having to worry about specific hardware or physical space. It makes me capable of providing machines to my students for a scheduled amount of time. It gives me storage space to upload content and to share data with my students or access them through my virtual hardware • RESEARCHER- It enables me to run experiments in many different environments and network topologies which I can provision easily, quickly and dynamically. I can have persistent or volatile machines according to my needs. I can also upload (besides my files) my own Images and launch Virtual Machines from them

13. okeanosservice • ~okeanos is set to deliver Infrastructure • Compute (Virtual Machines) • Network (Virtual Networks, private Ethernets (L2) or public IPv4/6) • and Storage (Virtual Disks) as a Service • Alpha2: from March 2012 - 2000 VMs – 1k alpha users • Beta December 2012 • Target group: GRNET’s customers • direct: IT depts of connected institutions • indirect: university students, researchers in academia • Users manage resources over • a simple, elegant UI, or • a REST API, for full programmatic control
