Jiri Chudoba, . . . . : alien, ALICE PPR production jobs
Institute of Physics AS CR (FZU) Contribution to HEP experiments in close collaboration with INP AS Rez , Charles University and Czech Technical University - ATLAS, ALICE, H1, D0, Auger
Computing equipment: 64 nodes PC farm, unix servers, Linux PCs Network -sitting on the 1 Gbps link connecting the FZU with the PASNET (Prague Academic and Scientific Network ) --> CESNET -> GEANT Ready to join the DataGrid testbed
The PC farm at the FZU (1) golias.farm.particle.cz Mass storage disc array 1TB: HP server TC4100, 256MB RAM, 15x73 GB SCSI HDD 10 TB tape drive unit SW - RH7.2 on all nodes PBS batch queing system
The PC farm at the FZU (2) - UI, CE, SE, RC ...
- Submitting jobs into testbed OK
- Not yet recognized by the testbed, must issue dg-job-submit -r golias.farm.particle.cz job.jdl
AliEn installed on golias by Jiri Chudoba without root privileges Version 1.3 of GENIUS installed by Roberto Barbera & Alberto Falzone in December last year, now v. 2.2.0 in the process of installation Quite a number of aliroot PPR production jobs run on the farm by Jiri Involved in the LCG (GDB) project
The PC farm at the FZU (3) The future plans: Continue the DataGrid and LCG activities Support for D0, ATLAS, ALICE computations Expand the mass storage disc space with another 6 TB StarLight project: optical connection to Amsterodam 2.5 Gb/s Arrange for a dedicated new room for the farm, where also two PC farms of the CESNET association will be installed Become a Tier-2 center for ATLAS (ALICE?)
The CESNET association Stands for Czech Educational and Scientific NETwork Czech NREN provider R&D on advanced network technologies and applications Internet2 international partner . . . . . . http://www.ces.net/about/
CESNET (2) Subcontractor in EDG project CESNET and FZU in Prague collaborate in the WP6 project of EDG CESNET CA provides PKI services for the Czech academic community (activity within WP6 project) Member of WP1 : development and implemention of the logging and bookkeeping services and of the services taking care of security requirements within the work management system
A PC 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
