Description
Abstract:
The D0 experiment faces many challenges enabling access to large
datasets for physicists on 4 continents. The strategy of solving these
problems on worlwide distributed computing clusters is followed.
Already since the begin of TEvatron RunII (March 2001) all Monte-Carlo
simulations are produced outside of Fermilab at remote systems. For
analyses
as system of regional analysis centers (RACs) was established which
supply the associated institutes with the data. This structure which
is similar the the Tier structure foreseen for LHC was used in autumn
2003 to rereprocess all D0-data with the uptodate and
much improved recontruction software.
As the first running experiment D0 has implemented and operated all
important computing dask of a high energy physics experiment on
worldwide distributed systems.
The experiences gained in D0 can be applied to judge the LHC
computing model.
