  1. (Inter)National activities Participation • EU-funded projects • i.e. GRIDCC, EGEE I-II-III, EGI-InSPIRE, PRACE 1IP-2IP, etc. • National-level projects • i.e. HellasGrid I-II, HellasHPC, etc. Key roles and responsibilities • EGI: task leader for User Community Technical Services • EGI: deputy task leader for the global Unified Middleware Distribution (UMD) repository and support processes • HellasGrid: National Grid application porting team • Regional Coordinator for the operations in the South Eastern Europe (EGEE/2009) • Country representative/coordinator for HellasGrid (EGEE/2009) 1

  2. Grid Computing (1) • Operation of two production-level Grid Clusters since 2005 (HG-02-IASA and GR-06-IASA) • Major stakeholder in HellasGrid (Greek National Grid Initiative) • Since 2005 our clusters handled: > 2.6M CPU hours; >1M concrete jobs • Extensive knowledge of gLite, UNICORE & ARC middleware • Testing and certification of grid/distributed services and middleware • Site & Region monitoring (stand-alone/hierarchical mode mainly using open-source frameworks i.e. Nagios, Ganglia, Cacti etc.) • Expertise on distributed systems security 2

  3. Grid Computing (2) Infrastructure: Computing/storage >150 cores >10TB reliable storage Networking 1Gigabit connectivity CISCO, eXtreme & HP stack switches General >150kBTU - A/C >100kVA – UPS >160kVA – outdoor power-generator 3

  4. Digital Repositories Development & hosting of the EGI-InSpire International Software Repository [http://repository.egi.eu/] (joint effort with GRNET, AUTH, ICCS) Release management of *all* Grid Middleware Distros (gLite, ARC, UNICORE, UMD [Unified Middleware Distribution]) Full support of the EGI release management process • Quality criteria verification process • Stage-Rollout process • Production level software provision 4

  5. International databases (1) IASA is responsible for the Development, Hosting & Maintenance of the International Grid Applications Database [http://appdb.egi.eu] The EGI Applications Database (AppDB) is a full-edged, community driven web portal, meant to act as: • a point-of-reference for scientific applications and tools available within the EGI infrastructure (over 400 registered applicationsand tools) • registry of experts involved in the development of the applications (over 600 registered scientists & developers) Main aims : • promote the significance of Grid in the e-Science • facilitate the reuse of applications and expertise that is available in National Grid Initiatives • help create a vibrant user community, with information owing inwards directly from involved individuals - developers and end-users alike [http://appdb.egi.eu] 5
