Correlation Based Combined Analysis Of FTA And GWA For Reliability And Performance Study Of Grid Environment
نویسندگان
چکیده
In this age of data and knowledge, Cloud, Grid and P2P systems are becoming common and advanced. Due to heterogeneous and distributed nature, Grid becomes more vulnerable to faults. Trace files are great way of storing and collecting fault and workload information from the system. FTA (Fault Trace Archive) and GWA (Grid Workload Archive) are two such trace files. Previously FTA and GWA have been individually analyzed by researchers, but in this research paper for the first time, we have analyzed the combination of FTA and GWA as a single research problem. Trace files have been joined based on the event timestamp values. Both the trace files have been analyzed to establish a correlation based model among node failures, failed jobs, number of nodes and failure duration. We have discovered that these factors are positively correlated with each other but to a different extent. Along with node failure frequency, failure resume time and node dedication factor, we have found that interactive jobs have a higher failure probability as compared to batch jobs.

Method for Conducting a Combined Analysis of Grid Environment’s Fta and Gwa through Session Based Mapping of Trace Variables
Grid computing environment due to its scale and heterogeneous nature is more vulnerable to faults. To store and analyze fault and workload information, FTA Fault Trace Archive and GWA Grid Workload Archive are used. Previously researchers have analyzed FTA and GWA as separate research problems but in this research paper we have proposed a method for conducting a combined analysis of FTA and GWA...

متن کاملCombined Use of Sensitivity Analysis and Hybrid Wavelet-PSO- ANFIS to Improve Dynamic Performance of DFIG-Based Wind Generation
In the past few decades, increasing growth of wind power plants causes different problems for the power quality in the grid. Normal and transient impacts of these units on the power grid clearly indicate the need to improve the quality of the electricity generated by them in the design of such systems. Improving the efficiency of the large-scale wind system is dependent on the control parameter...
متن کاملReliability and Availability Improvement in Economic Data Grid Environment Based On Clustering Approach
Abstract - One of the important problems in grid environments is data replication in grid sites. Reliability and availability of data replication in some cases is considered low. To separate sites with high reliability and high availability of sites with low availability and low reliability, clustering can be used. In this study, the data grid dynamically evaluate and predict the condition of t...
متن کاملQualitative and quantitative approaches to analyse reliability of a mechatronic system: a case
The main research intent of this paper is to introduce the use of fault tree analysis (FTA) and failure mode and effects analysis (FMEA) in conjunction to analyse the risk and reliability of a complex mechatronic system in both qualitative and quantitative manner. The major focus is on handling imprecise and vague information with the help of fuzzy synthesis of information. A complex mechatroni...
