The complexity and the dynamics of the Grid environment and of the emering workflow-based applications on the Grid require novel performance monitoring and analysis services in order to capture monitoring data at multiple levels of abstraction, to analyze the data and to correlate metrics among entities. In this paper, we present the design of distributed monitoring and performance analysis ser...

Performance monitoring tools play a critical role in the overall productivity of business organizations by providing the necessary means of measuring the performance of the system or server attributes of the organization. They measure system or server throughput and processor usage through programmed software or technological platforms. Their monitoring is extremely efficient such that Network ...

Monitoring is critical for providing robust, high performance Grid environment. Without monitoring mechanisms, it will be impossible to determine the status or health of environment. And so it will be difficult to use it effectively & efficiently. Monitoring data can be used for performance analysis, performance diagnosis, performance tuning, fault detection and scheduling. Due to the complexit...

Thirty low and 30 high anxious participants performed a speeded Go/noGo task during which they had to rely on evaluative feedback to infer whether their actions were timely (correct) or not. We focused on FRN, an ERP component that is sensitive to the valence of feedback. Depending on the context, neutral faces served either as positive or negative feedback. Whereas the FRN of low anxious indiv...

To examine the processes that support prospective remembering, previous research has often examined whether the presence of a prospective memory task slows overall responding on an ongoing task. Although slowed task performance suggests that monitoring is present, this method does not clearly establish whether monitoring is functionally related to prospective memory performance. According to th...
