GoG Farm

9 racks (800x600 mm) 22 PCs + 1 network switch per rack 2U chassis with 3 fans

– pros:• less space required

– cons:• add 240 euros per PC (aprox.)

• heat concentration

Local Network

24th May2002 10

Local Network All Worker Nodes have private IP addresses in the net 192.168.4.0/22

– secure environment– administrative independence from University

network management staff

Communication equipment have public IP addresses in the net 147.156.149.64/26– can be monitored and upgraded from University

centralized service

IV- ATLAS Computing

Data Challenges, involved in phase 1: • full chain implemented and tested at IFIC

•Event generator • Det. Simulation •Reconstruction •Analysis

• Files: Dijets and Zjets (10 Kevts)

• Computing Resources available from June to December:• 100 PC’s (4 KSpecInt95)

•Massive Production (10**7 evts for the whole ATLAS Coll.): •with EDG 1.2

•by the end of June
