| 摘要: |
| ChaRM是一种并行程序后向故障恢复与进程迁移系统.它不仅实现了对工作站机群系统瞬时故障的恢复,而且通过检查点设置时的Mirror存储技术和进程迁移技术,实现了对机群系统结点永久故障的恢复,并支持系统软硬件的在线维护、处理机资源的排他/限时使用和动态负载平衡等功能.文章主要介绍ChaRM系统的检查点设置与回卷恢复、进程迁移等实现技术,并给出了部分性能评测结果. |

| Abstract: |
| ChaRM is a checkpoint-based backward fault recovery and process migration system. It is designed to recovery the fault of NOWs (networks of workstations) by checkpointing and rollback recovery. It offers functions of on-line software and hardware maintenance, process migration and load balance, etc. ChaRM is able to run on NOWs that change over time due to failure, load or availability. As long as there is at least one node alive in the cluster, the computation will complete in an efficient manner. The checkpointing, rollback recovery and process migration techniques, and some performance evaluation results are discussed in this paper. |
| Key words: Checkpointing, rollback recovery, process migration, NOWs (networks of workstations). |
