| 摘要: |
| 在分布式计算系统中，进程迁移是一种在进程生命周期内将它从一台处理机传送到另一台处理机上，并使进程从其“断点”继续运行下去的方法．本文详细地讨论了在Ｗｕｌｏｒ—７５／３２系统和国外几个典型的分布式计算系统中实现进程迁移的方法，以及为实现进程迁移，对系统的其它机制——文件系统、通信机制和内核中有关部分所作的扩充． |

| Abstract: |
| In a distributed computing system,process migration is a method by which executing processes may be transferred between nodes during their lifetime and resumed from the switch off point in the destination node. This paper addresses at length the implementation ways of process migration in the Wulor 75/32 and other typical distributed computing systems, as well as extensions to other system facilities:file systems, communication mechanisms and OS kernel for implementing process migration. |
| Key words: Distributed system process migration finding idle machines interprocess communication mechanism performance optimization |
