Study on error-detecting approach for fault tolerance recomputing oriented parallel digital terrain analysis

摘要：

　　In recent years,the research of parallel digital terrain analysis has become a hot spot.Using the parallel computing technology to solve data intensive problems,and it has become a development trend in digital terrain analysis.On the other hand,with the development of hardware technology and new applications,how to ensure the reliability of the computing results is a one of the key problems.We can improve the systems ability to provide the right service by adopting fault tolerance technology properly.The paper proposes a parallel error-detecting approach which is based on a mixed mode of shared memory and distributed memory.By adopting the parallel comparison,it can improve the efficiency of fault tolerance recomputing.According to the error-detecting analysis of slope algorithm,it proves the effectiveness of error-detecting approach based on fault-tolerant recomputing and achieves minor overhead.
