The Internet-based virtual computing environment (iVCE) provides on-demand aggregation and autonomic collaboration mechanisms to facilitate the utilization of autonomous and dynamic Internet resources. Load balancing and fault tolerance are important issues when scheduling those transient resources. In this paper, we propose a mobility mechanism for the migration of various roles of agents in the...
Soft errors are a growing concern for computer reliability. To mitigate the effects of soft errors, a variety of software-based fault tolerance methodologies have been proposed for their low costs. Data duplication techniques have the advantage of flexible and general implementation with strong capacity for error detection. However, the trade-off between reliability, performance and memory overhead...
Soft errors are emerging as a new challenge in computer applications. Current studies about soft errors mainly focus on the circuit and architecture level. Few works discuss the impact of soft errors on programs. This paper presents a novel approach named PRASE, which can analyze the reliability of a program with the effect of soft errors. Based on the simple probability theory and the corresponding...
