Ccrc 08

CCRC’08

All 3 Polish sites participated in the recent CCRC’08

  • Joining in was quite painful

    • problems appeared in previously tested areas, due to high load

  • Finally all problems were overcome

    • many days of quiet running

  • Lot of lessons learnt

    • …but such was the purpose of this exercise!

Pledges and reality

Pledges and reality

  • Cracow and Warsaw had some problems to install all pledged resources on April 1st

    • … even though they were purchased long before!

    • Main problems were insufficient electrical power

  • For CCRC’08 almost all pledged resources were used

    • … by pushing away other users…

  • Cracow has now installed all necessary CPUs and most of the disks, the rest should be ready within days

  • In Warsaw the solution to problems has been found recently, but the installation will take a few weeks more

Conclusions

Conclusions

  • Polish Tier-2 Federation is ready for the first LHC data and eagerly awaits them!

  • All 3 sites participated successfully in CCRC’08

    • It was a very useful lesson!

  • There was some delay in installing some 2008 resources, but everything should be completed very soon

    • Inadequate disk/CPU ratio for ATLAS and ALICE will be corrected early in 2009, and of course in pledges too

  • We are very indebted to GridKa staff for all the help we are given!
