5. Cracow computing centre Available for LCG in early 2006: ● ~130 kSi2000 80 CPUs (Xeon 2.4 – 2.8 GHz) available now 200 CPUs (Xeon 2.8 Ghz) coming soon ● ~20 TB disk array

6. Warsaw computing centre Available for LCG in early 2006: ● ~290 kSi2000 180 CPUs (AMD Opteron 2.4GHz, 2GB RAM/CPU ) available now 40 CPUs (AMD dual-core, 4GB RAM/CPU) coming soon ● ~9 TB disk array

7. Poznań computing centre Available for LCG in early 2006: ● ~180 kSi2000 100 CPUs (Itanium 2GB RAM/CPU) available now ~90 more coming soon, details not yet fixed ● ~2 TB disk array ● ~5 TB tape storage ➔ Operation centre for Polish academic network

8. Tier-2 federation ● Poland is a federated Tier-2 ● HEP community rather small (~60 people) ● Each of the computing centres naturally will support mainly 1 experiment Cracow – ATLAS Warsaw – CMS Poznań – ALICE (because they have Itanium processors) ● This means that each centre will be about 1/3 of the average/small Tier2 for a given experiment

9. Oct-Feb Progress ● Procurement of new hardware finalized at Cracow (+200 CPU) and Warsaw (+88 CPU) ● Polish internal 1Gbit/s VLAN network setup between Poznan, Cracow, Warsaw finalized and tested ● Setup of the outbound connection from Poznan to Tier1 FZK Karlsruhe is under arrangements ● Pilot attempts of installation of services for SC4 have mostly succeeded, but services not yet in production
