Abstract :
The KLOE experiment at DAΦNE is largely devoted to the study of discrete symmetries in the KSKL system. During 2001-2002, KLOE collected 1.4×109φ decays, for a total data volume of nearly 200 TB. We describe the KLOE computing environment, outlining our solutions to issues of calibration, reconstruction, data reduction, and data access for analysis. We discuss the performance of the system, with particular emphasis on the data-processing and transfer rates, and also describe the generation of large Monte Carlo samples. The KLOE computing environment has been demonstrated to be flexible and scalable in the presence of rapidly evolving data taking conditions.
