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

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 ...

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
