GPUs have recently been explored as a new general-purpose computing platform, which are suitable for the acceleration of compute-intensive EDA applications. In this paper we describe a GPU-based one- to n-detection fault simulator for both stuck-at and transition faults, which demonstrates a 20X speedup over a commercial CPU-based fault simulator. We further show new fault-simulation-based test selection applications enabled by this accelerated fault simulation. Our results demonstrate that the tests selected from the applications achieve higher fault coverages for 1-to-n detections with steeper fault coverage curves, as well as a better delay test quality, in comparison with tests deterministically generated by commercial ATPG tools.
Relevance feedback based on SVM classifier shows a good performance recently but the finite feedback counts limited by user's patience and the small sample size problem are not solved well, Co-SVM does a good job ...

Web workloads are known to vary dynamically with time which poses a challenge to resource allocation among the applications. In this paper, we argue that the existing dynamic resource allocation based on resource utilization has some drawbacks in virtualized servers. Dynamic resource allocation directly based on real-time user experience is more reasonable and also has practical significance. To address the problem, we propose a system architecture that combines real time measurements and analysis of user experience for resource allocation. We evaluate our proposal using Webbench. The experiment results show that these techniques can judiciously allocate system resources.
