| 摘要: |
| 通过传递消息进行通信的并行程序, 由于受进程调度和消息等待时间变化的影响, 其执行结果可能是不确定的。这导致调试时相继执行不能再现先前的故障, 为此, 在并行调试环境中引入了追踪和重演机制。本文详细讨论了一种比较先进的追踪和重演算法及其工程实现。 |

| Abstract: |
| Executing result of parallel programs which communicate by passing messages, can be nondeterministic due to variations in process scheduling and message latencies. Such nondeterminacy can cause serious problems while debugging: subsequent executions of the program may not reproduce the original bug. Therefore, a tracing and replaying mechanism is introduced into parallel debugging environments. This paper discussed an advanced algorithm for tracing and replaying, and its implementation. |
