1. The first year of the Estonian Grid Andi Hektor, Mario Kadastik, Martti Raidal -- NICPB Lauri Anton, Hardi Teder -- EENet Konstantin Skaburskas -- Tartu Univ. Vahur Kotkas -- Tallinn Univ. of Tech. andi.hektor@cern.ch NGN Workshop in Linöping Oct 20, 2004

2. Birth of the Estonian Grid (EG) Jan 29, 2004: the CA (and the phone of the RA), the country GIIS, the first CE

3. Brief history of the EG Jan '04: first components of the EG: EG CA, country level GIIS and first test clusters Jan '04: NorduGrid technical meeting in Tallinn Feb '04: Centre of High Energy Physics and Computational Sciences at NICPB Mar '04: some first multiprocessor clusters join the EG Apr '04: CP/CPA draft for the EG CA May '04: first scientific software ported to the EG May '04: Grid laboratory at the Tartu University Jun '04: establishment of the technical coordination group of the EG Jun-Jul '04: first massive scientific calculations at the EG Okt '04: EG technical support group publishes the first article about the first scientific results produced with the EG

4. Brief history of the EG Oct 5-7 ’04: The first Baltic Grid meeting

5. Current situation of the EG Choice of middleware: NorduGrid ARC EG CA is trusted by EUGridPMA and NorduGrid 62 CPUs in the EG (Pentium4 2.2…3.0 GHz) The country GIIS registers to NorduGrids top level GIISes ☺ ☹

6. Technical support for the EG users Technical support and coordination group, 6 persons at the different institutions Support list: grid-tech@lists.eenet.ee Web: http://grid.eenet.ee

7. Know-how centres Estonian CERN CMS group at NICPB Porting CMS software to NorduGrid CERN Tier 2 plans http://www.nicpb.ee/centre UT Lab of Grid technology DOUG software Commercial applications UT Theoretical chemistry UNICORE, OpenMolGrid http://www.openmolgrid.org TUT Lab of cluster technology Environmental science Hardware systems Plans: bioinformatics, medical applications, nuclear safety

8. Structure of the EG CERN CMS software, Geant4, etc Software for nonlinear dynamics, etc DOUG software, ID- card, etc NICPBUTTUTEENet Technical support group Centre for HEP & comp. sciences EG CA Technical support group Country- level GIIS Cluster Laboratory Grid Laboratory EAS Commercial applications Lectures, seminars, user support

9. Political structure and cost of the EG The political structure of the EG - the steering committee of the EG is establishing - EENet, NICPB, TUT, UT The cost of the EG - 0 euros in this year - based volunteers in this year - 4-6 persons are involved, not full-time - the budget of the next year is open

10. Some excellent possibilities of the EG Electronic ID-card infrastructure (600 000 ID- cards), it is easy to use for the Grid Local experiences with E-money and rental software Good connections to NorduGrid

11. Support project for the commercial applications AS EGeen: analyse of gene information OÜ Nukufilm: animations and rendering OÜ Vendomar: testing of the applications AS Sertifitseerimiskeskus: ID-card and its applications AS Silmet: nuclear and radiation safety AS Tallinna Diagnostikakeskus: medical applications Other: Centre of Radiation Safety, the Ministry of Defence Estonian Grid, NorduGrid NICPB Institute of Physics at the UT Coordinator: Coordinator: The Lab of Grid Technology at the UT Companies: Collaboration:

12. Some applications: Geant4 (1/3) Medical applications Nuclear safety Materials for the nuclear industry

13. Mobile gamma spectrometry Need for modelling: Monte Carlo (Geant4) Computational power: NorduGridi, EG Collaboration: NICPB and UT in Estonia; STUK, HIP and MATINE in Finland Some applications: Geant4 (2/3)

14. Some applications: Biotech (3/3) EGeen, Estonian Gene Foundation Personalized medicine Analyse of the gene information on the Grid

15. First scientific results from the EG: nuclear safety calculations using Geant4 The total time of the computations was 417 CPU days. The speed of the CPUs used were between 2.4 GHz and 3.06 GHz (IntelPentium 4). In total there were 17 failed jobs (2.6%) during the computations, probably due to random hardware errors. There were 16 post-processing errors (2.5%) due to the instability of the hardware/software caused by the external factors: blackouts of electric grid, overheating, etc.

16. Thank you!
