Active replication on top of a structured peer-to-peer overlay is an attractive solution for transparently providing high availability to distributed applications. However, self-healing is necessary to ensure the availability of the replicated application despite node arrivals, failures or departures in the overlay. Self-healing means to automatically reconfigure the replica groups when changes in...
The information service is an important component of any Grid middleware as it helps users to find resources suitable for the execution of their applications. Traditional approaches based on data bases that have been designed for Grids of moderate size do not fit the requirements of wide-area large scale Grids composed of dozens of thousands highly dynamic nodes. In this paper, we propose a fully...
Fault tolerance is one of the key issues for large scale applications executed on high performance computing systems. In a cluster federation, clusters are gathered to provide huge computing power. To work efficiently on such systems, networks characteristics have to be taken into account: the latency between two nodes of different clusters is much higher than the latency between two nodes of the...
