A View on Fault Tolerant Techniques Applied for Mediogrid
نویسندگان
چکیده
In this paper we analyze the characteristics of fault tolerance for grid systems, which serves as a basis to identify the features and techniques of the Globus framework and the way these can be applied for the MedioGrid project. Based on the general MedioGrid architecture and the fault tolerant analysis, we suggest an extension of dynamic replication strategies to address data life cycle using dynamic policies. Finally, we highlight some directions in order to enhance the fault tolerance at the MedioGrid application level, both simple and parallel.

متن کاملEnabling Testability of Fault-Tolerant Circuits by Means of -Checkable Voters
The reliability of a fault-tolerant circuit may be drastically impaired by the presence of maskable faults that never affect its functionality. Design for testability (DFT) techniques have to be applied to make maskable faults detectable. During the testing phase, traditional DFT schemes inhibit fault masking and/or activate additional observation/control paths through the circuit. Such schemes...
