1. HPC and Cloud Technologies in Greece and South Eastern Europe Tryfon Chiotis GRNET

2. 2 state-owned company (SA) under GSRT established in 1998 provide advanced e-infrastructures/services to the Greek academic and research institutions: –National and international connectivity –Infrastructures/services (network, computing, storage) to the community promotion and dissemination of ICT in the public and private sector

3. 3 > 100 universities, research centers, academic organizations > 15.000 schools > 1.000.000 users Dark fiber backbone ( Nx10 Gbps) access 1 || 10 Gbps per institution International connectivity through GEANT network 3*10 Gbps Neutral point for the Greek Internet Exchange (GRIX ) node – peering all Greek ISPs at 10Gbps each GRID services Storage Services –(e.g. Online Storage-Pithos, 50 or 100 GB/user–6500 users per day) VPS VM provisioning (>400 VMs) & Public Cloud (~okeanos) 2 DataCenters (NRC & Ministry of Education premises) GRNET numbers:

4. 4 35 PoPs –8410km fibers (IRU) MANs Attiki & Thessaloniki DF loops 33 cities Single-mode fiber pair 15-years IRUs Availability >> 99%

5. 5 Cloud Services Virtual Private Servers (VPS) –Persistent volumes/longevity/non volatile VMs (RACKSPACE style) Public Cloud Service ~okeanos (VM, volumes) –Short lived/volatile instances (high churn rate) Amazon (AWS) style Online File Storage Service (Amazon S3 like) –Files, groups, REST API

6. 6 Public Cloud Service ~okeanos Deliver IaaS to GRNETs customers direct: IT depts of connected institutions indirect: university students, researchers in academia Other IaaS efforts (Amazon, Rackspace, Nimbula, Nebula, GoGrid etc) Amazon EC2 not an end-user service Need to develop custom UI, AAI layers Vendor lock-in Unsuitable for IT depts persistent, long-term servers, custom networking requirements Nimbula Director offers similar functionality

8. GRNET and HPC -Invited by the Ministry of Development to submit a proposal which will support Greeces participation in PRACE. -Goal is the development of a national HPC infrastructure that will join PRACEs Tier-1 European infrastructure. -Budget 3.5 MEuro -Procurement and installation of HPC infrastructure -Operation and provision of support services

9. Technical specs and target applications - Aiming for at least a ~150 Tflops supercomputing system -Petabyte level storage -Hosting in GRNETs existing Datacenter -Support for a wide range of scientific disciplines: Biomedicince, Bioinformatics, Computational Engineering, Physics, Metoerology, Climatology, Seismology, Computational Chemistry etc. -Based on the results of the HellasHPC feasibility study -National survey among 29 academic and research institutes (summer 2010) -Collected requirements from 200 scientific applications developed by 162 research teams from various scientific domains

10. High-Performance & Supercomputing: HP-SEE 33 months 3,88 m project, 540MMs 120 Tflops aggregate 2 BlueGene machines Larger procurements coming up Close links to PRACE Possibility of a joint Tier-1 centre Balance of national and EC funds Towards long-term sustainable European hierarchical model 10

11. Key results: HPC Initiatives Support the setup of national HPC task forces or their incorporation in existing structures –National HPC initiatives guidelines provided –Governance, organizational, operational, training and dissemination details provided –D2.2: National HPC task-force modeling and organizational guidelines Recommendations for HPC centers procurement provided –Legal, procedural, technical and planning –D2.1: Procurement guidelines analysis Regional collaboration models in definition: Draft resource sharing MoU in place Liaison with PRACE, other pan-European activities, and world-wide initiatives

12. HP-SEE: Project Objectives Objective 1 – Empowering multi-disciplinary virtual research communities Objective 2 – Deploying integrated infrastructure for virtual research communities –Including a GEANT link to Southern Caucasus Objective 3 – Policy development and stimulating regional inclusion in pan-European HPC trends Objective 4 – Strengthening the regional and national human network

13. Crucial for regional cooperation: policy development and political support Project: South-East European Area for eInfrastructures Area: "INFRA-2008-3.1: ERA-NET supporting cooperation for research infrastructures in all S&T fields Start: 1 April 2009 Duration: 36 months Project type: Coordination and support action Partnership: Ministry partners + eInfra partners programme manager partners Core Objective: Develop and strengthen the coordination and cooperation of national eInfrastructures programmes in the region of South- East Europe.
