I.- Main Areas of Interest
Fabric Management and Operation– Automatization– Monitoring
Experiment -oriented use of the farm– Data Challenges in ATLAS (Monte Carlo
Production)– Data Analysis

II.- Infrastructure at IFIC GoG (Grupo de Ordenadores para el GRID) Farm
192 Athlon PC (134 IFIC + 58 ICMOL)– VIA KT133A & KT266A based MotherBoard– CPU: AMD Athlon K7 @ 1.2 & 1.4 GHz– RAM: 2x512 Mbytes (SDRAM & DDR SDRAM)– HD: 40 Gbytes– NIC: 3COM 905CX & RealTek RTL8139 (Fast
Ethernet + PXE)– 2U chassis
24th May2002 5
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 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
