Abstract:

Operating system (OS) models are widely used to alleviate the overwhelmed complexity of running system-level simulation of software applications on specific OS implementation. Nevertheless, current OS modeling approaches are unable to maintain both simulation speed and accuracy when dealing with preemptive scheduling. This paper proposes a Data-dependency-Oriented Modeling (DOM) approach. By guaranteeing the order of shared variable accesses, accurate simulation results are obtained. Meanwhile, the simulation effort of our approach is considerably less than that of the conventional Cycle-Accurate (CA) modeling approach, thereby leading to high simulation speed, 42 to 223 million instructions per second (MIPS) or 114 times faster, than CA modeling as supported by our experimental results.
