Grid activities in Czech Republic Jiri Kosina <kosina@fzu. cz> Institute of Physics of the Academy of Sciences of the Czech Republic http: //www. fzu. cz/
Experiments Czech Republic is active in(1) ● ● ATLAS, ALICE, D 0 and STAR – detector simulation activities, reconstruction and data analysis in running projects - main participants are Institute of Physics, Charles University and Czech Technical University Facilities created by EDG are starting to be used by HEP projects under schedule of LCG in the scope of GDB, to which Czech Republic also contributes
Institutions involved ● CESNET (http: //www. cesnet. cz/) ● Charles University in Prague (http: //www. cuni. cz/) ● ● Czech Technical University in Prague (http: //www. cvut. cz/) Institute of Physics AS CR (http: //www. fzu. cz/)
Institutions involved – CESNET(1) ● ● ● Czech scientific network provider – provides all participating subjects with connectivity Founded by Czech universities and AS CR. It's main goal is to provide and develop main backbone academic network infrastructure. Currently their network (called CESNET 2) provides on their backbone speeds of gigabites per second and connection to GEANT and other scientific networks.
Institutions involved – CESNET(2)
Institutions involved – CESNET(3) ● ● 12 Gbps connection to GEANT 2 Gbps connection to NIX (Peering with czech ISPs) ● 622 Mbps connection to USA(Telia) ● 1 Gbps Czech. Light connection
Institutions involved – CESNET(4) ● ● Participating in European Data. Grid project – member of WP 1 (workload management) and WP 7 (network monitoring) work packages. Certification authority was established during participation on EDG project – issuing certificates to czech academical subjects
Institutions involved – CESNET(5) ● Meta. Center (http: //meta. cesnet. c z/) - project to establish virtual computer allowing efficient utilization of HW and SW of project participants
Institutions involved – FZU(1) ● Dedicated server farm for HEP and Grid computing (34 x dual 1. 13 Ghz PIII, 1 TB disk array, currently experimenting with new 10 TB disk array)
Institutions involved – FZU(2) ● ● Member of WP 6 work package – farm is running EDG 1. 4 software, for testbed purposes Currently installation of LCG-tier 1 software (based on EDG software) is in progress.
Institutions involved – contacts ● ● Jan Svec <svecj@fzu. cz> - FZU farm and network system manager, D 0 experiment Jiri Kosina <kosina@fzu. cz> - installation of grid software at FZU, ALICE experiment, network and system management Jiri Chudoba <Jiri. Chudoba@cern. ch> ATLAS experiment <pcclust@cesnet. cz> - CESNET's PC clusters
Experiments Czech Republic is active in ● ● ● Czech republic is also member of EGEE project proposal. EGEE is going to be successor of EDG project, mainly sponsored by EU More information about EGEE can be found at http: //cern. ch/egee/
Summary – Grid infrastructure ● ● Basic Grid infrastructure has been established during last year and further expansion due to research or commercial needs in future shouldn't be problematic CESNET provides good international network connectivity – 12 Gbps over GEANT (http: //www. dante. net/geant/) – Recently we have connected our farm to Czech. Light optical network (1 Gbps via
