Distributed computing environment for data intensive tasks by use of Metadispatcher

Data processing in GRID environment requires access to the data stored in different locations, but for the end users this process should be as transparent as possible. This paper describes our experience of Metadispatcher (Kovalenko, Nucl. Instr. and Meth. A 502 (2003) 411.) usage as a core for the Data Intensive Grid. This is effective system to distribute tasks between computer clusters. We have developed and tested file transfer services for data managing in the GRID environment. These services allow to hide the complex process of the data exchange between storage and computational clusters. Additional information services were also developed. These services provide user-friendly interface for task processing.
