Presentation Transcript

  1. The LCG-GRID infrastructure of HEP/NTUA Lab N. Vidiadakis ge00218@mail.ntua.gr High Energy Physics Laboratory, National Technical University of Athens

  2. HEP/NTUA Laboratory • The HEP/NTUA Collaboration is an effort within NTUA to advance • Research and Development in areas which are of interest in the High Energy Physics sector; the ATLAS/LHC project in particular • related techniques in other sciences that can fruitfully be applied within HEP realm or LHC Computing Grid (LCG) • The Collaboration includes: • scientists that have an affiliation with the CERN organization • experts in computing science and network management • NTUA students.

  3. What is the Grid? “An infrastructure that enables flexible, secure, coordinatedresource sharingamongdynamiccollections of individuals, institutions and resources” Ian Foster and Carl Kesselman • Generalized and globalized form of distributed computing • Virtual unified computational resource • Shared CPUs, Storage, Network (and Software and Sensors… etc) • Why was it created? • Storage and processing of LHC data

  4. Where is the Grid?

  5. CrossGrid: • Next Step:

  6. GR-03-HEPNTUA • 16 P4 Northwood HyperThreading (32 jobslots) with 1024 MB RAM each and 80GB SATA HDDs • 1TB of storage • Coming soon: upgrade to 56 CPUs total and 2,5Tb storage

  7. GR-03-HEPNTUA Monitoring Data

  8. Activities on Diploma Thesis and Grid Experimentation

  9. Newton-Raphson Fractals • Newton-Raphson is a root-finding algorithm. • f(z) = z7 - 20*z5 - z3 – 2 • 50 worker nodes used • Created by Dimitrios Apostolou

  10. POV-Ray Farm Rendering • Official benchmark of • POV-Ray • 3D Rendering creates • extreme CPU load • 32 worker nodes used • Total time could be • reduced to a theoretical • 1/32 of the time on a • single system. In practice • it is a bit more than that. Created by Nikolaos Vidiadakis

  11. Lorentz Attractor • The equations that govern the Lorenz attractor are: • 32 worker nodes used Created by Nikolas Karalis

  12. Grid Benchmarking • A collaboration between • University of Aegean and our • Laboratory resulted in • this Grid benchmarking activity • We retrieved information such • as: cpu model and vendor, harddisk • space, memory size, floating point • operations… Created by John Kouvakis

  13. Grid Benchmarking • We can provide helpful information for users that have specific needs

  14. LiveWN • Ability to expand existing clusters with no installation/configuration • Integration to LCG/GLite Middleware using LiveCD technology • It will run everywhere a 32bit Linux operating system can boot and get an IP address • Impressive versatility! • Created by John Kouretis

  15. Poster • 22-24 July 2006: Technical Chamber of Greece organized “Conference of Research and Technology” • Our participation was with this poster on the left
