Farm provided by CESNET

CESNET is providing their PC farm connected to the 1.2Gbps backbone in frame of the collaboration with FZU in WP6

The configuration 16 + 1 dual processor nodes : PIII

at 700 MHz, 1 GB memory, 9 GB HDD running Debian 2.2 Linux PBS batch system

Farm is mostly used for D0 MC production Two nodes used for testing Grid software

October 2002 INFN Catania 17

Guided by our interests and by the possibilities available for us within the LHCC Grid Project

initiative in Praguewe have specified our objectives such as ...

October 2002 INFN Catania 18

Our plans

To test EDG 1.2 after it gets installed on the PC farm at FZU in Prague and prospectively the same with GENIUS

To install/use/test/maintain alien on nodes available at the FZU in Prague (with/without root privileges)

To purchase and install a couple of rack servers designated for integration into the FZU PC farm (on the way) and this way become "shareholders" in the initiative of this CC to become a Tier2 site in the LHC Computing Grid Project

To get a Charles University EPP Department student to get involved into maintaining and testing alien, possibly also EDG software, on the the cluster at FZU
