  2. 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. 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. 4. Brief history of the EG  Oct 5-7 ’04: The first Baltic Grid meeting
  5. 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 0 40 80 120 160 200 Jan-04 Mar-04 May-04 Jul-04 Aug-04 Oct-04 Time NumberofCPUs ☺ ☹
  6. 6. Technical support for the EG users  Technical support and coordination group, 6 persons at the different institutions  Support list:  Web:
  7. 7. Know-how centres  Estonian CERN CMS group at NICPB Porting CMS software to NorduGrid CERN Tier 2 plans  UT Lab of Grid technology DOUG software Commercial applications  UT Theoretical chemistry UNICORE, OpenMolGrid  TUT Lab of cluster technology Environmental science Hardware systems  Plans: bioinformatics, medical applications, nuclear safety
  8. 8. Structure of the EG CERN CMS software, Geant4, etc Software for nonlinear dynamics, etc DOUG software, ID- card, etc NICPB UTTUTEENet Technical support group Centre for HEP & comp. sciences EG CA Technical support group Country- level GIIS Cluster Laboratory Grid Laboratory EA S Commercial applications Lectures, seminars, user support
  9. 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. 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. 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:Companies: Collaboration:Collaboration:
  12. 12. Some applications: Geant4 (1/3)  Medical applications  Nuclear safety  Materials for the nuclear industry
  13. 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. 14. Some applications: Biotech (3/3)  EGeen, Estonian Gene Foundation  Personalized medicine  Analyse of the gene information on the Grid
  15. 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. 94% 3% 3% 0% Correct jobs During comp Post-proc Other
