Main Abstract:
The work reported in this paper is motivated towards validating an alternative approach for fault tolerance over traditional methods like checkpointing that constrain efficacious fault tolerance. Can agent intelligence be used to achieve fault tolerant parallel computing systems? If so, "What agent capabilities are required for fault tolerance?", "What parallel computational tasks can benefit from such agent capabilities?" and "How can agent capabilities be implemented for fault tolerance?" need to be addressed. Cognitive capabilities essential for achieving fault tolerance through agents are considered. Parallel reduction algorithms are identified as a class of algorithms that can benefit from cognitive agent capabilities. The Message Passing Interface is utilized for implementing an intelligent agent based approach. Preliminary results obtained from the experiments validate the feasibility of an agent based approach for achieving fault tolerance in parallel computing systems.

[1]: As the size and popularity of computer clusters go on growing, fault tolerance is becoming a crucial factor to ensure high performance and reliability for applications. To provide this facility, a checkpoint mechanism is used to recover a failed parallel application rolling it back to an execution moment prior to occurrence of the failure. In this work we present a mechanism for managing checkpoint operations during the failures automatically. This mechanism records periodically the application's context, identifies failed nodes and restarts MPI processes on the remaining nodes, allowing the continuity of the application and taking advantage of the computing accomplished previously. We describe a lot of changes inside source of the LAM MPI. Experiments with an application for recognizing DNA similarity showed that despite the overhead caused by periodic checkpoints, the benefits can reach about 50 on a small cluster.
In [1] , the concept of automatic checkpointing is introduced in LAM MPI middleware. The strategy records the context of an application periodically, identifies failed nodes and restarts MPI processes only on failed nodes, hence allowing continuity of the executing application by taking advantage of the computing done previously.
