Advance reservation can ensure the future availability of the Grid's heterogeneous resources and help a scheduler to produce better schedules. We propose a new resource mapping technique for jobs of a Grid workflow in an advance reservation environment. Using the Dynamic Critical Path for Grid (DCP-G) scheduling algorithm's job selection method, our(More)
— Text document clustering is an important issue in the field of information retrieval and web mining. Huge amount of text documents are needed to be clustered so that search engines can retrieve these documents efficiently and effectively. In this paper we present a novel approach for clustering text documents based on Maximal Frequent Item-set (MFI). Our(More)
Frequent itemsets (FIs) mining is a prime research area in association rule mining. The customary techniques find FIs or its variants on the basis of either support threshold value or by setting two generic parameters, i.e., N (topmost itemsets) and $$K_\mathrm{{max}}$$ K max (size of the itemsets). However, users are unable to mine the absolute desired(More)
Scheduling workflows in Grids with the goal of minimizing the completion time is a challenging optimisation problem. Communication times between dependent tasks affect the schedule length only if the tasks are scheduled on different resources, and this makes it difficult to predict the critical path of the scheduled workflow. To address this difficulty, we(More)
