Query: Computing System for the Belle Experiment   We describe the offline computing system of the Belle experiment, consisting
of a computing farm with one thousand IA-32 CPUs. Up to now, the Belle
experiment has accumulated more than 120 fb$^{-1}$ of data, which is the world
largest $B\bar{B}$ sample at the $\Upsilon(4S)$ energy. The data have to be
processed with a single version of reconstruction software and calibration
constants to perform precise measurements of $B$ meson decays. In addition,
Monte Carlo samples three times larger than the real beam data are generated.
To fullfill our computing needs, we have constructed the computing system with
90(300) quad(dual) CPU PC servers from multiple vendors as a central processing
system. The details of this computing system and performance of data processing
with the current model are presented.
