| 摘 要： | 研究了一种基于PVM的交错一致检查点算法，该算法对系统资源的战胜率小，冻结时间短，尤其当计算节点具有多个处理器时，进行检查点操作不会由于对存储器的争用而导致用户进程的冻结，提高了检查点算法的效率，同时，该算法的IPC机制是基于PVM的消息传递机制，因而所有操作对用户程序是透明的。

| Abstract: | This paper presents a staggered consistent checkpointing based on PVM. This algorithm has low occupation probability to system resource and short freezing time. When some computing nodes in system have more than one processor, this algorithm will improve the efficiency of checkpointing. And the checkpoint operations shall not conduce competition for storage that will result in freezing the user processes. The IPC mechanism of this algorithm is based on message passing mechanism of PVM so that all operations are transparent to users. |
