17. October 2002 INFN Catania 17 Guided by our interests and by the possibilities available for us within the LHCC Grid Project initiative in Prague we have specified our objectives such as...

18. 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
