| 摘 要： | 提出了一种新的MPI消息日志机制及实现原理．它基于发送方的混合日志协议，采用收消息和发消息的全监管机制，使每个进程的消息收、发过程与检查点操作时机相对独立．当一支进程失效时，只回滚该进程本身，减小了因为单支进程失效给整个执行过程带来的进度影响，也使得并行程序具有类似于独立运行程序的自由度．出错过程的相对独立也为同时容多支进程出错提供了，前提．

| Abstract: | The infrastructure of MPI message logging was introduced by adopting a logging system relatively independent from each other. The sender based message logging with pessimistic protocol was improved to tolerate more than one failure. The burdensome task of maintaining the consistent system state that each progress should be rollback all independently when a failure occurred was abstained. This can reduce the totally running time of the global task and make the progress have the disengagement approach to independent programs. |
