6. HEPIX - HEPNT, 1 Nov. 2000 Milos Lokajicek, IP AS CR, Prague6 Computing Independent smaller HEP groups - share university/institutes infrastructure with local HEP installation Research Centre for Particle Physics and Elementary particle physics department of IP - 40 physicists –basic unix/linux infrastructure available (servers, users’ home directories, automatic back-up/restore service, project disk space, CERN ASIS software, hepix scripts, b/w and color printing, exchange DLT units,...), end 2000 new 1TB file server upgrade user access via PCs with X-emulation (Exceed) Main platforms –unix - HP, SUN, DEC, SGi, growing linux (young generation and production), W95/98/NT/2000 independent nodes

7. HEPIX - HEPNT, 1 Nov. 2000 Milos Lokajicek, IP AS CR, Prague7 Grid activities Associated contractor to DATAGRID in collaboration with –METACENTER project in CESNET (grid-like project between Czech supercomputing centers) middleware, testbed, networking –HEP groups testbed, HEP applications –Target is Tier2 centre Testbed by end 2000 Linux farm, 64 processors (Prague and Brno, 2.5 Gb network), 1 TB disk space First application - simulation for D0 on part of the farm

8. HEPIX - HEPNT, 1 Nov. 2000 Milos Lokajicek, IP AS CR, Prague8 Summary HEP community in the Czech Republic gets new impulses - founded Research Center for particle physics Contributions to important HEP experiments Good quality of internal networking, external networking depends on availability of financial resources Computing follows standard HEP evolution Starting involvement with DATAGRID project
