Modeling and performance analysis of the VEGA grid system

In this paper, we propose four general queueing models based on input and server distributions, to analyze a special grid system, VEGA grid system version 1.1 (VEGA1.1). The mean queue lengths and mean waiting times of these models are deduced. The two classic applications, the computing-oriented application (blast computing) and online transaction processing application (air booking service) are employed to analyze and evaluate the grid system and the models. Meanwhile, we validate VEGA's four prominent characteristics, versatile services, enabling intelligence, global uniformity and autonomous control. Finally, we analyze the experiment results, predict the behavior of VEGA1.1 in equilibrium and point out the bottlenecks of the system
