摘要

我们报告了新算法的设计和仿真,这些算法将确保应用软件在处理单元(PU)可能出现故障的MIMD系统上正确运行。随着故障率的增加,这些算法对随机任务图的效果进行了评估。还研究了一个特定应用程序的示例(快速傅立叶变换),我们为此构建了任务图,然后模拟其在不同处理器故障率值下的执行。

Failure detection algorithms for a reliable execution of parallel programs
We report on the design and simulation of novel algorithms which will ensure that application software runs correctly on a MIMD system in which processing units (PU) can fail. The effect of these algorithms is evaluated for random task graphs using simulation as failure rates increase. An example of a specific application is also examined (the Fast Fourier Transform) for which we construct the task graph and then simulate its execution under various values of the failure rates of processors.
