The CESNET association
Stands for Czech Educational and Scientific NETwork Longtime Czech NationalResearch Educational Network
operator & developer (since 1993) R&D on advanced network technologies and applications Shareholder of the Dante Internet2 international partner Participant of the GEANT project CESNET CA provides PKI services for the Czech academic
community (activity within WP6 project) http://www.cesnet.cz/pki/
October 2002 INFN Catania 13
The CESNET (2)
Now CESNET2 - new generation of the networking technologies: Packet-over-SONET/SDH technology : all core lines are
operating at 2.5 Gbps Backbone nodes using Cisco products Multicasting provided, part of the Mbone network IP version6 and 6bone connectivity provided

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
