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

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 2000Linux farm, 64 processors (Prague and Brno, 2.5 Gb network), 1 TB disk space

• First application - simulation for D0 on part of the farm

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
