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...
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...
Monitoring distributed applications executed on a computational Grid is challenging since they are executed on several heterogeneous nodes belonging to different administrative domains. An application monitoring service should provide users and administrators with useful and dependable data on the applications executed on the Grid. We present in this paper a grid application monitoring service designed...
