COMPUTING NEEDS OF LHC EXPERIMENTS AND PROSPECTS FOR WORLDWIDE GRID FOR PARTICLE PHYSICS
Malecki P., Szymocha T., Turala M., Bold T., Nyczyk P., Ozieblo A.
Several new experiments in particle physics are being prepared by
large international community. They will generate data at the rate of
100-200 MByte/s over a number of years, which will result in many PBytes (1015 Bytes) of
information. This data will have to be made accessible
to a large international community of researchers, and as such it
calls for a new approach to the problem of data analysis. Estimates
of the computing needs of future experiments, as well as scenarios of
overcoming potential difficulties, are presented, based on the studies
conducted by LHC consortium and GRID computing projects. Short information on the
operation of the LHC Computing GRID project is provided, together with the description of the
first installations. Examples of large-scale Monte-Carlo simulations are also given.
