Method for Conducting a Combined Analysis of Grid Environment’s FTA And GWA through Session Based Mapping of Trace Variables

摘要

Grid computing environment due to its scale and heterogeneous nature is more vulnerable to faults. Tostore and analyze fault and workload information, FTA Fault Trace Archive and GWA Grid WorkloadArchive are used. Previously researchers have analyzed FTA and GWA as separate research problems butin this research paper we have proposed a method for conducting a combined analysis of FTA and GWAbased on session based mapping of trace file variables. This is the first attempt to conduct a combinedanalysis of these two trace files. Along with the step by step process of combining trace files we have alsoincluded do’s and don’ts while conducting this analysis .Through this combined analysis we haveestablished a correlation based relationship among number of node failures, number of failed jobs, failureduration and number of nodes. We have found that these variables are positively correlated with differentcorrelation coefficients.
