Simulating the Farm Production System Using the MONARC Simulation Tool

The simulation program developed by the “Models of Networked Analysis at Regional Centers“(MONARC) project is a powerful and flexible tool for simulating the behavior of large scale distributed computing systems,In this study,we further validate this simulation tool in a large-scale distributed farm computing system.We also report the usage of this simulation tool to identify the bottlenecks and limitations of our farm system.     

Experience Using Different DBMSs in Prototyping a Book—Keeper for ATLAS‘ DAQ Software

The Online Book-keeper(OBK) was developed to keep track of past data taking activity,as well as providing the hardware and software conditions during physics data taking to the scientists doing offline analysis.The approach adopted to build the OBK was to develop a series of prototypes,experlimenting and comparing different DBMS systems for data storage,In this paper we describe the implemented prototypes,analyse their different characteristics and present the results obtained using a common set of tests.
