中文摘要：

当前并发程序容错机制处理方式单一、效率较低。为此,提出一种适用于多种并发程序错误处理的容错机制。通过在编译及运行过程中对程序进行异常处理,并在异常发生时根据设置的检查点对程序进行回滚和防错误处理,以实现并发程序容错。实验结果表明,该容错机制可有效检测并发程序中的错误,在不增加程序总体运行时间的情况下达到比较理想的容错效果。

英文摘要：

Currently most concurrent program fault-tolerant mechanisms can not handle multi-bugs in programs and are also of low effectiveness. This paper presents a concurrent program fault-tolerant framework based on exception handling, which can be used to handle different concurrent program bugs by supporting from compile-time and runtime work and rollbacking program status to certain checkpoints in order to achieve the objective of fault-tolerance of concurrency bugs. Experimental results show that this framework can help to detect concurrency bugs effectively and recover program states from exceptions to normal states.
