VASA: A Simulator Infrastructure with Adjustable Fidelity
نویسندگان
چکیده
This article presents Vasa, a configurable high-performance multiprocessor simulation package for the Virtutech Simics full-system simulator. Vasa includes models of multilevel caches, store buffers, interconnects and memory controllers and can model complex out-of-order SMT/CMPprocessors in great detail. However, it can also be run in two less detailed simulation modes being up to 287 times faster on average. We compare the simulation results from a 16-way cache coherent multiprocessor system with four 4-way SMT/CMP processors in the three simulation modes. Our results indicate that for many architectural studies, it is justifiable to run the simulations in a faster less detailed mode as long as it is not the behavior of the processor itself or the first level caches that is being studied.

Model-Based Testing for Objective Fidelity Evaluation of Engineering and Research Flight Simulators
Simulator fidelity has been defined as the conformance of a flight simulator to the characteristics of the real aircraft. Objective fidelity evaluation is an engineering approach that attacks the fidelity problem with comparison of simulator and the actual system behavior over some quantitative measures. Testing can be pronounced as the fundamental mean for this comparison. From the utilization...
متن کاملDevelopment of a Driving Simulator for Human- Vehicle Interaction Studies
Driving simulators are a valuable resource for human-vehicle interaction studies. Unfortunately, commercially available driving simulators are expensive and use software that sometimes offers limited flexibility or customizability. Exploiting the maximum potential of simulation requires that all aspects of the simulation software and the virtual driving environment be adjustable. However, in cr...
متن کاملFeasibility and fidelity of practising surgical fixation on a virtual ulna bone.
BACKGROUND Surgical simulators provide a safe environment to learn and practise psychomotor skills. A goal for these simulators is to achieve high levels of fidelity. The purpose of this study was to develop a reliable surgical simulator fidelity questionnaire and to assess whether a newly developed virtual haptic simulator for fixation of an ulna has comparable levels of fidelity as Sawbones. ...
متن کاملField simulation for RFID-based in door location sensing algorithm
In recent years, positioning systems for indoor areas using the Radio Frequency Identification (RFID) infrastructure have been suggested. Such systems make use of location fingerprinting algorithm for determining the location of object carrying RF tag. However, due to the environmental influence, theoretical model for these algorithms often fails to function in real world application, which nec...
متن کاملComparison of high- and low equipment fidelity during paediatric simulation team training: a case control study
BACKGROUND High-fidelity patient simulators in team training are becoming popular, though research showing benefits of the training process compared to low-fidelity models is rare. We explored in situ training for paediatric teams in an emergency department using a low-fidelity model (plastic doll) and a high-fidelity paediatric simulator, keeping other contextual factors constant. The goal was...
