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

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

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

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

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
