Validation of the MONARC simulation tools Original Research Article

The objective of the MONARC project is to identify baseline computing models that could provide viable solutions meeting the data analysis needs of the LHC experiments. A powerful and flexible set of simulation tools has been developed to model the performance of distributed computing resources for a set of reconstruction and analysis tasks. In this paper we report the validation of the simulation tools using the testbed environments with Objectivity/DB over LAN and WAN connections. A simple and effective way to parameterize and evaluate the concurrent database access over network has been established.
