Fault Tolerance in Distributed Paradigms
Distributed systems are responsible for providing the main execution platform for High Performance Computing (HPC). As distributed systems can be homogeneous (cluster) as well as heterogeneous (grid and cloud etc), they are prone to different kinds of problems. The issues in distributed systems can be Security, Quality of Service, Resource Selection and Fault Tolerance etc. Fault tolerance is responsible for handling the reliability and availability of distributed systems. It is not feasible to ignore job failures in distributed environments where long and persistent commitments of resources are required.
