Supporting Dynamic Migration in Tightly Coupled Grid Applications

Liang Chen, Qian Zhu, Gagan Agrawal
2006 ACM/IEEE SC 2006 Conference (SC'06)  
We provide an alternative to basic checkpointing, using the notion of Light-weight Summary Structure (LSS), to enable efficient migration.  ...  This allows us to perform low-cost process migration, as long as such memory can be identified by an application developer, and migration is performed only at these points.  ...  For the CluStream application, we used the KDD-CUP'99 Network Intrusion Detection dataset. For Dist-Freq-Counting, we used a dataset generated by the IBM synthetic data generator [4] .  ...

Decentralized Dynamic Query Optimization based on Mobiles Agents for Large Scale Data Integration Systems

Mohammad Hussein
2012 International Journal of Computer Applications  
In this paper, we propose an execution model based on mobile agents for the distributed dynamic query optimization.  ...  The query processing in large scale distributed mediations systems raises new problems and presents real challenges: efficiency of access, communication, confidentiality of access, availability of data  ...  In response to these events, dynamic query optimization queries methods [1, 2, 9, 10, 21, 24, 25, 26, 29] have been developed.  ...

Model-driven software migration into service-oriented architectures

Andreas Fuhr, Tassilo Horn, Volker Riediger, Andreas Winter
2011 Computer Science - Research and Development  
The proposal explores how graph-based querying and transformation techniques enable the integration of legacy assets into a new SOA and how these techniques can be integrated into the overall migration  ...  The presented approach is applied to the identification and migration of services in an open source Java software system.  ...  These symbols can be combined using regular operators: sequence, iteration ( * and +), alternative (|) and so on. Listing 2 shows a query for finding member classes.  ...
