Software Fault -tolerance is an effective and reliable design technique and Recovery Block Scheme is an important Software Fault-tolerant measure. Here is the brief introduction of the implementation of Software Fault-tolerant technique and the design pattern by employing software redundancy and then proposes the implementation of Recovery Block Scheme. Firstly, based on the program block’s fault captured by exception-progressing mechanism, it applies the Command Pattern and Active Objective Pattern to manage and schedule arithmetic unit to achieve rollback, clears the data generated by fault operation block and restores to the state before the operation. The design pattern provides a widely available recovery block schemes design pattern, simplifies the implementation of arithmetic unit and gives the core algorithm through Java.

Abstract A new interconnection network topology called Hierarchical Hexagon HH(n) is proposed for massively parallel systems. The new network uses a hexagon as the primary building block and grows hierarchically. Our proposed network is shown to be superior to the star based and the hypercube networks, with respect to node degree, diameter, network cost, and fault tolerance. We thoroughly analyze different topological parameters of the proposed topology including fault tolerance routing and embedding Hamiltonian cycle.
